Motion

Standard

In science class we used motion sensors to make graphs going straight, increasing, decreasing and zigzag.  Also we had to match graphs with the one’s that were already made. Here is the graph and how I did it.

unnamed-7

For this graph we had to walk backwards and stay and come back and stay and go back and stay.

unnamed-6

For this graph we had to walk forward and stay and walk forward and stay and then go back.unnamed-5

This was a bit different because it was velocity and it did not work and we had not figured out how to do it.

unnamed-4

 

Same for this one as well.

unnamed-2

For this graph we had to stand still.

unnamed-1

For this graph we had to be away from the motion sensors and come waking forward.

unnamed-3

For this graph we had to stay close to the motion sensors and walk backwards.

unnamed

For this graph we had to walk back and forth from the sensors.

 

 

Eye Disction.

Standard

In Science class we learned about the eye and we had to discct a pig eye with a partner and my partner was Kelly.Here are the photos.

The optic nerve helps send the message to the brain.

Sorry there is no photo of the Pupil and the lens because they got squished while we were cutting the eye.

Ipad Elements and Compound

Standard

In our grade 7 we all got Ipads and in science class we were wondering what effect dose it have in the world and what is in the Ipad and if we should keep the program or make it bigger or just end it..

These are the 3 elements I found in the Ipad.

Element

Where is it?

What does it do?

Where does it come from?

Holmium(Ho)

It is in the front-facing camera.

It helps when people do things like facetime, skype E.T.C. It helps not to crack while face chatting.

Holmium mainly comes from the earths crust.

Copper(Cu)

It is in the motherboard memory chip of the Ipad.

It helps the ipad memory to stay and not get lost or disappear.

Copper is mainly mined in Peru, Arizona, MIchigan and Chile.

Aluminum(Al)

It is used in the Ipad case.

It helps so that the Ipad does not break and is able to use it for a long time.

Aluminum is mainly mined in Australia and Brazil.

These are the 3 Compounds I found in the Ipad.

Compound

Where is it?

What does it do?

Where does it come from?

Electrical cells

It is in the battery pack

It helps the batter to stay longer and store more.

Metal(Cu,Sn,Al,Mn,P,Si)

It is inside the phone.

It helps the display data cable to stay together as one and not break apart.

Metal mainly is mined for U.K or Germany.

Bronze(Cu,Al,Mn,P,Si)

It is inside the phone.

It helps the display data cable to stay together as one and not break apart.

I think that the issue while getting the Ipad ingredients are the safety. It might be a good item for us to learn with and play around with but for the miners its a very different situation. In a place called Bangka Island Indonesia they live a very sad life because every week about one person dies from mining. Also they only get 5 dollars(540yen) a hour mining in the hot burning sun risking their life just for their family. The mining company thinks that the safety of the miners are not their responsibility because the company is just buying from them and it was their choice to mine.
Another story is about a father with two sons getting stuck on the underground while mining tins. All of a sudden their is a earthquake and the walls fall on top of him getting him squashed in the middle. After the earthquake the other miners tried to help the man out by digging with their hands. But sadly they were not able to rescue him so his two sons will have to work and study at the same time to save the family.
The sad thing about it is not only do people die but people also don’t get to use the Ipads, Iphone, computers E.T.C. All they do is mine and offer them to the company and sell and get little amount of money. All the things go to America, Europe, Japan, Republic of Korea, China E.T.C.
I think that we should keep the Ipad program the way it is because it might be dangerous for the people mining but we still are helping them get money and be able to sell things. If people don’t buy computers, Ipad,E.T.C the company would not have enough money to buy the ingredients from the miners then the miners would no have enough money to live with. It might be a dangerous job for the miners but still it is helping them by buying the things. Some people might say to end the Ipad program and give the money that we use to buy the ipads to them but we are not sure if the money is going to them or not. Also if it gets to the country we are not sure how and where people use it in the country.
