Are plastic getting into our food?

There is a growing evidence that plastics are getting into our food. With billion of plastics floating on the ocean, there is a high chance that it is poisoning the marine life. Not only that, but there is also an indication of plastic polluting the soil.

With nearly 14 billion pounds of plastic getting dumped in the ocean. This is most likely to pollute and damage the marine life. Unfortunately, billions of plastics are floating in the ocean and break into small pieces-microplastic- and feeding the marine animals. With the microplastics working their way to the marine animals, that means that plastic is now part of our food chain.

According to soil scientists, they have found that not only our ocean is polluted by plastic but also our soil. They said that the third of all plastic waste contained in the sewage. Significantly, sewage is used to fertilised farm, this means that the microplastic is ending up into our soil.

We use the soil to plant our food, so if the soil is polluted. Our crops could also be affected. Furthermore, animals sneak into farms to eat the crops. So if the crops are affected. The animals that ate the crops will also get affected. While us humans hunt these animals for food. Not knowing that those animals are carrying microplastic that can give many diseases.  

Nowadays, everything has plastic in it. Our food, our water, and even the animals are carrying plastic to their body. It could take time to eliminate plastic, but If we start now, we can take one step to the future where there is no more plastics that could harm us. Stop recycling! start reducing!

Passion Project

What is your passion project?

We are now doing a football tournament for year 7 and 8 because the other groups are also doing basketball. 

What have you learnt/done so far?

We've emailed Mr Hillard if we can use the two Gym and sports equipment.

How does this help you achieve your passion project?

This would help us to achieve our passion project if Mr Hillard allows us to use the gym and the sports equipment.

What is your next step?

Our next step is to plan how are we going to run it

What evidence do you have that this is something you need to do?

We have to learn the rules of the game because only 1 of us know the rules. 

Please provide a screenshot or photographic evidence of your work so far.

Passion Project

What am I learning?
we are learning to work in groups and trying to achieve the things we planned on doing. We know that by finishing the work together. I am working with Vince, Gian, Jhade, Roswell, and Ray. We are planning to run an event where we will train the two school primary kids and after that, we will verse them.

What is S.W.O.T?

S.W.O.T is the group's strengths, weaknesses, opportunities, and threats. Here is our S.W.O.T

S.W.O.T Analysis

Topic: Sport

Strengths Fast Learners One of us  has experience in coaching We stay on task We are capable of finishing the work that is given.	Weaknesses We can’t speak English fluently. We are not confident enough to show or present in front of the class. Some of us does not know how to coach and ref a game
Opportunities We will have better communication skills. The community will be more active Hornby High School will be well known to their love of sports. Our school will be well known for improving or taking action for our community.	Threats The other schools might not let us teach them Some kids might not want to play basketball and something instead. Kids might not commit or work with us when we are teaching them.

Action: We are going to coach primary students to play basketball and then put on a tournament for them to compete again each other.

By doing S.W.O.T, we now know what our weaknesses and strengths and this will help us in the future.

Hurricane Katrina

A very powerful storm that forms over the North and South equator of America is called ‘Hurricane’. Hurricane is a fierce storm that forms over warm oceans. Significantly, the ocean’s temperature must be up to 26.5° or more is required for a hurricane to form. With the winds that can reach up to 270 km/hr are able to create a storm surge and storm tides that can destroy buildings and houses. Not only that, heavy rainfall can lead to an extreme flooding, which can take a lot of lives.

Matariki

Matariki, a group of 7 stars, can be seen in the north-east sky. People call it by many names like ‘Mother with 6 daughters’, ‘The 7 sisters’, and  ‘Gods eye’. Interestingly, it only appears in the last few days of May and can last for 3 days. These cluster of stars is important in the olden days because it signals the people that the winter is coming and they need to start to gather and preserve the crops. Nowadays, Matariki is still important because it gathers the whanau and remembers their ancestors who had passed away.

Earthquake proof house

What makes a home earthquake proof?

The structure has to withstand, or move undamaged, the earthquake's force should pass through the frame of the house to its foundation and leave the house intact.
The walls of the house should be anchored securely to foundation slabs. Otherwise, the house will slide along the foundation slab. The anchor bolts should fasten the sill plate.

My team's design

Was it successful?
Our design was successful because we make sure that every corner is equal.

What do architects do to make super tall building safe?
The architects make sure the foundation are strong and deep under the ground.

ENE Reflection

What went well today?
We have finally posted the diagram. We are now doing the natural and cultural effects of Typhoon Haiyan.

What can you improve the next lesson?
 we have to research harder so we can finish the topic by monday

Rock Cycle

ENE Reflection

What went well today?
I'm close on finishing the diagram and Andrew is starting to write the story about it.

What didn't go well today?
I could've finished the diagram if I had enough time.

How will you improve that next lesson?
I will try to work fast

ENE Reflection

What went well today?
We started to make the diagram on 'How Typhoons formed?'

What didn't go well today?
We thought that we can use 'My simple show' so we have to draw our diagram

Tomorrow we're going to finish the diagram

Extreme Natural Event Reflection

what went well today?

Is there anything you need help with? who can help you?

What didn't go well today?
We got confused on what we were doing because we didn't kind of understand the question.
The things we did last Monday was wrong so we delete it then we picked a new topic and that waste our time a little bit.

How will you improve on that next lesson?
Make sure to understand the instruction.

Volcanoes

 How do Volcanoes form? 
When the tectonic plates are being pushed together or pulled apart, volcanoes are created. Volcanoes formed when the magma from the Earth's mantle rises to the earth's surface. As the volcano continues to erupt, it will get bigger and bigger.
When a volcano erupts, it releases a toxic ash that can spread miles away. It also causes earthquakes, floods, mudslides, and rock falls. The lava can travel really far and it destroys, burns buries everything in its path.

Olympus Mons
Olympus Mons is a volcano on Mars and it is also the largest volcano in the solar system. The Olympus Mons is 3 times taller than the Mt Everest. It is located in the Tharsis region of Mars along with the three other large volcanoes. It was formed from a hotspot that flowed for thousands or millions of years.

Facts about Olympus Mons

• It is the largest Volcano in the whole solar system
• Olympus Mons is 3 times taller than Mt Everest
• The size of the Olympus Mons is almost the size of Arizona
• The entire chain of Hawaiian island would fit inside the Olympus Mons

Cool facts about Volcanoes

• Volcanic lighting occurs within the cloud of ash during an eruption, and it is created by the friction of the ash rushing to the surface. 
• When a volcano is erupting, it can trigger tsunamis, flash floods, earthquakes, mudslides, and rockfalls.
• There are more than 500 active volcanoes around the world. More than half of these volcanoes are part of the "Ring of Fire".
• The sound of an erupting volcano can be quiet and hissing explosive and booming. The loud cracks travel hundreds of miles away and can cause hearing loss and broken glass.
• 'Dormant' is called to the volcanoes that didn't erupt for years but still active.

Particle Theory of Matter - Convection

Aim -  To observe convection in a liquid
Equipment: 200 mL beaker, water, tweezers, a crystal potassium permanganate, a drinking straw, Bunsen burner, heat mat, tripod and gauze mat.

Method: 

1. Set up a Bunsen burner on a heatproof mat. Put the gauze mat on the tripod but leave it just to one side of the Bunsen burner.
2. Fill a 200 mL beaker with 150 mL of cold water.
3. Place the beaker on top of the tripod and gauze and allow it to settle for a few minutes.
4. Carefully insert a drinking straw down one side of the beaker, ensure the straw is touching the bottom of the beaker. Be careful as you do not want to disturb the water too much.
5. Using tweezers, drop a crystal of potassium permanganate down on the bottom of the beaker.
6. Very gently, so to not disturb the water, remove the straw.
7. Light the Bunsen and slide it under the tripod so that you are only heating the outside of the beaker where the crystal is. Observe. 

 Observation:
The crystal dissolved and made a thick purple cloud and dissolved more rapidly on the side of the beaker. The purple moved up the beaker side and then formed a big circle and made its way up around the beaker.

Explanation:  This is because of the convection current

NZ Growing - DTE Reflection

Intro 

G'day mates! I am writing a reflection about our project called 'NZ Growing' in DTE. This project took us about 5 weeks to finish, and we have had learned a lot of things through this project. We've been told to get into a group of 3 or 4 and as always. Vince, and Thamhie, and I are in the same group, again! this time, I was the group leader. Next, we've been told to choose a topic to do in 5 weeks time. We chose the topic called 'maintaining Water Supply'. 

Reflection

Just like I said 'Maintaining Water Supply' is what we are doing. We chose this topic because we were getting heaps of ideas for it, we also think that we can smash this topic really good. Every topic has a challenge you had to do. For our topic, the challenge was to 'create a new way for farmers to quickly identify that there is a problem and locate where it is'.  

In our first lesson doing this topic, Mr Carter sent us a video to watch that relates to the topic we chose so we can get an idea of what to make. After that, Mr Carter told us to choose an enabler. We have to choose two enablers to use in what we're going to make. We have to really think about on what we are going to choose because once you've picked it, you can't change it. The two enablers that we chose was 'Nanotechnology' and 'Network and Sensors'.

We picked 'Network and Sensors' because we have to use a sensor for our design to detect a leak. The other thing is, the 'Network' we can use the network to email the farmer when there is a leak detected. 
We picked 'Nanotechnology' because it can repair broken stuff and it can make it more durable and stronger. 

Once we've picked our two enablers. We had a discussion on what we are going to make. We had so many ideas that we came up, but we only have to choose one. After we had a discussion, we agreed on one design, which is my design. My design is going to be a tube looking with a sensor, network, and a nanotechnology. This tube was going to be installed around the water pipes. 

Here is how our design will work. When the sensor detects a leak, it will send a message to the farmer/s that there is a leak on one of the pipes. When the farmer received the message, farmer/s will send the nanotech to fix the broken pipes. 

When we had an idea we went to 'Tinkercad' to create our design. It took us about 3-4 weeks to create and finish the design. Here is what our prototype looks like.

This is the prototype that we built in Tinkercad. I know it has heaps of things going on with it, so let me describe it to you. The big orange tube is the water leak detector and the little yellow circle beside it is the sensor. The tube has 2 wires attached to it. These two wires are separated because once it meets each other it will activate the alarm. Electricity moves in water, so when water touches the two wires. The water will connect the two wires and be turning the alarm on.


DLO
In the last two weeks, we've been told to make a presentation about our topic. We will be presenting it to the whole class. Thamhie and Vince both did the presentation on 'Prezi' while I make the notes. Mr Carter said that he doesn't want to see a paragraph on the presentation that we're making.

Here is the link to the presentation that we made about our topic. Click Me =D

Questions

What do you think about our prototype? will it help the farmers save water?

English writing

All zoos should be shut down and release all the animals to their natural habitat.

I think zoos should be shut down and should not. That's because some animals in the zoo are powerless and can’t survive by themselves in the wild. Maybe because they are hurt, sick, or just can’t survive without a help. However, capturing animals to put in zoos should be shut down. Because those animals don’t need a help to survive and they are fine living on their own. This is one of the reasons why capturing animals are bad. The animals that have been captured for no reason suicides because they don’t like living in cages and get disturbed by the people visiting. In my opinion, zoos should not be shut down because it’s a really cool place to go because you can see animals you’ve seen in books. It also makes the children happy when they see their favourite animals like Lions, Eagles, Monkeys, and so many more!

English Writing

Animals aren’t toys!

Hunting animals for sports should be banned this is because animals have feelings too, they aren’t made so we can use them for entertainment, and it’s also an animal abuse.

Hunting animals is cruel and hunting animals to use in sports is even worse because animals have feelings like humans, they have families like humans, and they love humans like we love animals. Animals are just like humans, but they are just in a different form. Hunting them is like us being arrested and put in jail. I mean like, who wants to be in jail? NO ONE! Yeah exactly, no one wants to be imprisoned and get treated terribly. So, for animals, getting hunted is like they are being arrested and put in jail and gets treated horribly. When they get told what to do, and they didn't do it, they will be punished for it. For example, you saw a dog walks like a person, it means, it's owner abuse and hurt the dog to make it walk like a person, and us humans we didn't know what the dog has been true through to entertain us.  So I wonder if people who abuse animals was put to the animals' position and get abuse like what he did. Will he stop abusing animals?

Creative Writing - SOST

My life in London is remarkably awful, horrible, and hard. I can't earn enough money to feed myself, and I always get sick because of the terrible pollution and the lack of clean water. I have to skip eating because I have to save enough money so I can get out of London and move to New Zealand. 

I always hated London because it's overpopulated, dirty and there's a lot of diseases. The diseases spread extremely fast because the streets are very dirty and damped. There is also no hospital nearby, so if you are ill, you will surely die. The kids work in the factory at a young age to help their parents. They work for long hours without a wage. I have to live in a house with several families living because I couldn't afford the rent of the house if I'm the only one's going to live in it. Living in a house with many people is very disgusting because you have to use the same water everyone uses to take a bath because it's hard to find enough clean water for everyone.

My journey on the ship was worse than my experience in London. My life on the ship was horrible because I was in the poor section of the ship and it was hot and crowded. I can see people dying directly in front of me, and just by staring at them, I can see that they have been through in a lot of pain.    

When I arrived in New Zealand, I was very cheerful that I've made it that far. I can smell the fresh air, and I can see clean running water everywhere. I can earn a lot of money to feed myself, and I can still have enough money to buy the things I want. There is a lot of opportunities and exciting jobs you can get in New Zealand. And the best thing I can get is, I can rent my own house, and I don't have to live with several families. I also don't need to bathe in used water because there's enough clean water for the people to take a bath. 

Since I have moved to New Zealand, my life has never been better like my life right, now and it's still getting better and better. I already have forgotten my past, and I don't want to think about it anymore. I hope that every people in London have the same life as me because they also deserve to have a better life and experience I am experiencing now. 

How to use a Lathe

Today we've been introduced in Lathe. A lathe is a tool that rotates the material about an axis rotation to do multiple procedures such as cutting, sanding, drilling and turning with tools that are applied to the workpiece to create an object with symmetry about that axis.

How to set up a lathe:

1. Slide the live centre in the headstock and the centre in the tailstock.
2. Put a guide bar in between the two centres.
3. Put the dial indicator on the stand, and then put the stand on the carriage.
4. Apply pressure towards the bar with the dial indicator
5. Once the pressure is applied, move the carriage along the bar. (The gauge should not move, and if it didn't move, it means it's balanced.
6. Slide the chuck on the head and turn the screw clockwise on the head until it's tight.
7. Turn the chuck by your hand to check that everything is snug.
8. put the tool bit on the tool post.
9. Align the tool with the dead centre, and then put the material in the chuck.
10. And that's it, you're done!

Safety around using a Lathe:

• Wear safety glasses
• Don't wear any jewellery because it might get caught on the lathe
• Make sure that everything is snug
• Make sure the floor is free and nothing can trip you
• Never put your hand near the lathe when it's turned on

Here is a video on 'how to set up a tool on the lathe'.

HHS amazing art work went missing!!

HHS amazing artwork went missing!

Description of the artwork:

Lindley was the person presented on the artwork.
The artwork was printed on A4 paper and the print is a little bit smaller than A4.
The face almost covered the whole print and the face is leaning in the left.
The expression on the face is serious.
The portrait has been composed as an open cropped head.
The eyelid has a cross-hatching pattern and the side of the face has different thickness of lines the eyebrow is a little bit thick. There's also line patterns on the chick.
The hair has a lighter tone because there's a lot of lines presented on the part.

The tone of the print is darker on the bottom and lighter on the top because there's a lot of cuts around the top part and few on the bottom. There's a lot of patterns going on the top part.

Wind Racers Experiment

Aim: Is to build a design that will travel the furthest.

Equipment:
- trolley
-cardboard
- tale
- paper
- string
- scissors

Method:
My plan is to start making all the elements I need to create this project. I will start a part of the cardboard that will be rolled up like a tube taped.  It will then taped to the trolley and just to secure it a bit more a string will be running from the top and around the trolley. Then a semi-circle will be formed of the cardboard to tape the top of the paper mast to it. Two holes will be penetrated into the middle of the hole. If possible make another stabilizer with the cardboard for the bottom.

Results:

Our wind racer went a distance of 11 meters in a time of 25 seconds. Using the formula of speed=distance/time I can calculate the speed of my wind racer

v = d/t

   =11 / 25

   = 0.44

"Mobile phones control people’s lives"

Most people rely on their mobile phones these days because they can do a lot of things that can make your life easier, but they can also be a dangerous thing. Mobile phones are really popular these modern days because they are easy to use and really affordable. Nevertheless, mobile phones can be a truly dangerous thing because when you focus too much on your phone, you’re not realising that it's slowly harming your body, and sometimes it can also kill people. For example, you are using your phone while charging and you didn’t realise that it’s overheating, and then it suddenly explode right into your face. All that things can happen at an unexpected time and unexpected places, so, be really careful with your phones. Mobile phones can be really helpful, but if you get obsessed with it; it can change your life, forever!

School is the best place to make mistakes

School is the best place to make mistakes

School is the best place to make mistakes because you are learning and it’s normal to do things incorrectly the first time. A few reasons I have are that you will learn from your mistakes because when you make a mistake there’s got to be a way to solve it, you just need to figure it out what is it or how to make your mistake right. You come to school to learn new things and learning new things is not easy. Of course, you won’t get things right for the first time unless you’re a smart ass and won't get a single one wrong. Its free to ask the teachers for help if you're struggling, they are there to help students when help is needed.

Modal verb practice - Term 3 plan

This term I have to practice more in Badminton because there's gonna be a tournament because it's my first time joining a sports tournament.

To practice more I need to attend every training because we only have 1 training per week.

To attend training I should know what time the training is so I will not miss it.

I could ask my coach what time the training is so I can be sure the right time.

I might also practice at home so I can practice even more.

Hollow Earth

Modern science holds that the Earth is unbroken series of, crust, and liquid magma surrounding a dense, hot core made primarily of iron and nickel. But not everyone is convinced. In the 17th century, some scientist came up with a new theory that the Earth is actually hollow.

Even today, a force of people believed that the Earth is hollow are fighting valiantly to validate their ideas through books, websites, meetings, and some extremely travel plans.

Rodney Cluff said that "the shell of the Earth is about 800 miles thick, from the outside to the inner surface". Half the planet is taken up by the surface weight, and then there's empty space. In the centre of the hollow, there is an interior sun that us divided by day and night sides. Other parts of the theory is that near the North and South pole are substantial openings that lead into the interior.

Tower Defence

Intro:
 For the last few weeks, we've been trying to do as much as we can to finish the game but it's not enough because it's so much harder than what we expected it to be, even though we did some changes throughout the time we have to make it easier as possible, but still, we didn't manage to finish the game.

 Reflection:
 I've learned so many things doing this work. I've learned that you need to start on a little work before you start the big ones because if you prefer to start on a big one, you'll get stuck to it because you don't have any idea what to do.

Making a tower defence game is really hard because no one in my team had an experience of making a game.  We could've chosen to make an app instead of a game so it's easier and it's also in our knowledge range.
My group actually did pretty well but it's not enough for this topic because we had some problems like we can't find a tower defence template in Applab so we didn't have a choice but to do it in Scratch.com. Working in scratch is really hard because it's different to Applab. It took us about 1 week to figure it out how to use it properly, but yeah, 1 week wasted figuring out a website. My team decided to do a different job to make the process a bit quicker. Vince accepted to do the coding because he kinda knows how to use Scratch better than me and Thamhie. Thamhie chose to do a background for the game in scratch and my job is to design towers, which I'm good at because I like editing and recreating things to make it better.

I like my group because we can communicate better and we know each other. However, working with your friends can sometimes slow the working progress because you'll just be going to mock around and spending time having fun together even though you have work to do, but if your team is mature enough you can have fun and do the work at the same time.

This is all the designs and codes we have made. That's all the towers I've made. The poison tower was my first design but it took me a little while to finish it so I change the towers into circles so it's easier. I used Pixlr to create those towers because that's the only editor I know how to use better. I wanted to do more towers but I don't have enough time because I wasted most of my time creating a 1 high graphic tower. The codes were done by Vince, he had a template to copy but some of the code needs to do by himself so he was a bit confused. Vince also designed the levels because he wanted to do it, he only finishes 1 level but he was close on finishing the 2nd level. The background where the start button is was made by Thamhie. She did so many designs but she didn't like most of them.

Questions
Do you think you can finish a game if you have a chance to make one? What game would you make?

Electricity Circuit

Electricity Circuit

Equipment:

1. Wire
2. Bulbs 
3. Battery

Method:

1. Gather needed Equipment
2. Plug the battery in
3. Attach the wires to the battery
4. Attach the wires to the bulb
5. Turn your battery on

Observations:

There was no light the first time we connected the wire, bulbs and battery. After a few attempts, we got the bulb shining. We tried different circuit diagrams to show the voltage of the bulb. Circuit one was brighter because it didn't have to share the voltage with any other bulbs. Between circuit two and three,  two had to share the voltage between two bulbs. We then measured the ammeter of the circuit.

What would happen if a black hole suddenly appeared next to Earth?

What would happen if a black hole suddenly appeared next to Earth? In short, the Earth will be doomed, but what exactly would happen?

First of all, there are 3 properties of a black hole, it can be measured in mass, spin and electric charge. These are the only 3 things the scientists know about black hole since all the information about it is lost; meaning no matter how heavy an object is that gets pulled into the black hole, all that will be left of its mass. 

However, scientists have stated a solution to the black hole information by proposing that some of the "lost" information can be recovered using holographic prints and quantum teleportation. 

Black hole mass is the most important because the mass of the black hole and the gravitational force generates and that's what causes the destruction of nearby objects. 
If you can get too close to a black hole, you will begin to stretch like spaghetti scientist called this effect "spaghettification".

Cave Art

What am I learning? I  am learning to write a story using only symbols and pictures to create a story that represents a moment in past time.

How does the work show my learning? the work we are currently doing in social studies is cave art!  Thousands of years back people used cave art to tell story's and create timelines, so by us attempting to create our own story using cave art it gives us a better understanding because we've actually done our own little cave art drawing.

What am I wondering??? I wonder why people used cave art, who was the first person to even establish this way of storytelling I wonder why they used this way of storytelling.

How can I use this learning? I can use this learning to help me with my cave art drawings and by learning about cave art it has given me a better understanding of how people used

to create these stories using only a stick and some type of ink or whatever they used back then, and the things they must have seen to have this much detail in their drawings.

I wonder what will happen to us after we die

I wonder what will happen to us after we die.

A lot of people have been asking 'Where do we go after we die or what's gonna happen to us after we die?'. No one can tell what will happen to us when we die because of no one can die and then come back to life to tell what will be going to happen to us after we die. Even scientists don't know the answer.

How to make Hokey Pokey

EQUIPMENT:
50g of sugar
1/2 tablespoon of water
1 tablespoon of golden syrup
1/2 tablespoon if bicarbonate of soda

METHOD:

1. Put the ingredients except for the bicarbonate of soda into a saucepan and place on a low heat
2. Stir until the sugar has dissolved. Raise the heat slightly so that it bubbles, and stir occasionally until you cannot feel any sugar at the bottom of the pan. 
3. take off the heat
4. Aff bicarbonate of soda and stir!
5. Watch what happens - it should all froth up with bubbles in the pan 
6. Pour out into your tinfoil sheet
7. Allow to cool  

This is what our Hokey Pokey looks like. The sweetness is perfect and the texture is fine. I think we're the only team who got the perfect result. This is the first time we cook something in science, so I'm really happy because I like Science and cooking.

Public art is a waste of time and money.

Drill gauge & F shape with safety

We have been working on Drill gage and F shape for about 14 weeks now. I am glad that I had a chance to finish it because some people didn't have enough time to finish their work.

This is what I have done for the last 14 weeks. Doing this project is not a big deal for me because I've done Metal tech last year so I kind of know how to do it. However, the F shape is a little difficult to do because you have to file it right or else it will not fit. The drill gage is not that hard because all you have to do is drill it and file the edges. 

Equipment:

60x25 ferrous steel

scriber

Engineers blue

Hax saw

File

Ruler

Vernier caliper

Method:

First, you have to get a two 60x20 ferrous steel and then clean both side of the 2 piece until you think it's clean. Second, add engineers blue on one side of the piece, after the engineers blue is dry, get a scriber and mark the right measurement. After you've done that, go ahead get a hax saw and cut the part that you don't need. Once you've finish cutting get a file and clean the edges and make sure the 2 piece can fit together after you did that clean your work and you're done.

Equipment

Method:

 Get a metal same as the one you use for your F shape. Just like what you did in F shape, you have to clean it and put engineers blue so you can mark your measurements. Go ahead and find the drills you need and drill the holes. After you done drilling, go to the buffing machine to polish your work so you can oil dip it. 

Safety 

Bench Drill - In terms of using a drill you have to wear safety glasses to protect your eyes from bits flying around. You need a partner to help you turn on and off, just in case things go wrong you can turn off the drill.

Buffing machine -  Using the buffing machine, you have to wear a face shield to protect your face just in case your work flies.

Oil Dipping - When oil dipping your work you have to wear an overall suit to protect you from the fire, gloves to protect your hand from heat, and safety glasses to protect your eyes.
