What did we do to help?

We went outside we were allowed around our whole school and we picked up as much rubbish as we could in 29 minutes. We managed to pick up more then a whole bucket.

What are your thoughts?

I think we should do this more often just to know were trying to do something about it and were not just listening to what the feed says. Do something about it.

What do you want people to know?

We need to save the world by picking up our rubbish and not littering because its kill the earth and mostly our sea life because there eating the rubbish which is our food source.

Social Studys - Protecting our planet

 In the Antarctic ice is melting which means our sea level will rise which will cause major floods. The Polar bears habitats are going melt Scientists point out that sea levels have risen and fallen substantially over Earth's 4.6billion-year history. 

But the recent rate of global sea level rise has departed from the average rate of the past two to three thousand years and is rising more rapidly about one tenth of an inch a year. 

A continuation or acceleration of that trend has the potential to cause striking changes in the world's coastlines. Where the earthquakes hit

What did the video encourage us to think about?

How can we save the sea life, by throwing rubbish away properly and not littering so it gets to the ocean and the sea life eats it which then kills them.

What do you think about this?

I think it's sad that sea life is dying because of us not recycling properly. Most sea life produce for us as in whales fertilize the water keeping the sea life alive and it's basically 85% of our oxygen

What is something that you could do to reduce pollution?

Recycle properly

Test for the Presence of Oxygen

 Aim: To carry out a test for the presence of oxygen gas (O2)

Equipment: A pea-sized amount of manganese dioxide (MnO2), boiling tube, bottle of hydrogen peroxide (H2O2), safety glasses, wooden splint, bunsen burner (if not using a lighter instead), test tube rack.

Method: 

1. Light your bunsen burner (if not using a lighter instead).

2. Add the manganese dioxide to the boiling tube and place it in your test tube rack.

3. Add 2 mL of hydrogen peroxide.

4. Light a splint and let it burn for a while.

5. Blow the splint out and insert the glowing embers into the mouth of the boiling tube

Results: When I blew the wooden splint out and put it into the head of the boiling tube it had set the wooden splint back on fire.

Discussion: When I blew the wooden splint out and put it into the head of the boiling tube it had set the wooden splint back on fire. (The same as the results)

Conclusion: It did work however next time I wouldn’t put the splint in the boiling tube as slow as I did, next time I’ll put it in straight away instead of waiting a few seconds then putting it in the tube.

Blog - Metals & Acids

 Aim: To show that hydrogen gas is produced when a metal reacts with acid.

Equipment: A test tube, a boiling tube, Bunsen burner (A liters better), wooden splint, a bottle of acid, a piece of metal and safety glasses.

Method:

1. Light your bunsen burner (If you're using one).

2. Add a sample of metal to your test tube. Add 2 mL of acid.

3. Carefully invert the boiling tube above the test tube containing the metal and acid.

4. Hold the test tubes together for a few minutes, allowing time for the inverted boiling tube to fill with gas.

5. When you think the tube is full, your lab partner should light a wooden splint.

6. Carefully, but quickly, tilt the boiling tube full of gas upwards and insert the burning splint into the mouth if the test tube

Observations: It's called the pop test because once you insert the splint in the test tube it’ll make a slight high pitched sound / Beep.

Results: “Once you insert the splint in the test tube it’ll make a slight high pitched sound / Beep.”... Its made a pop

Discussion: We were testing for hydrogen gas

Conclusion: It worked really well because it made the pop it was supposed to make. Something I would have done differently was to get the wooden splint in the test tube faster so it would make a loud and bigger pop.
