Hurumanu / Science Decomposing and Recycling

Aim: To learn about the rate that different materials decompose. 

Hypothesis: I think Banana or Bread will rot the faster because banana will get warm and it will get all rotted and Bread can get all soggy.

Materials:

1.  Bread + water.
2.  Paper.
3.  Banana.
4.  Styrophone.   
5.  4 testTubes.  
6. Test tube rack

Steps:

1.   Collect the Materials abd take them to your table.
2.  Sort out the Materials.
3.  Add all the 4 equipment into the 4 tubes.
4.  Get a sticky note off the teacher and write your groups name.

Findings:

TODAY	Colour	Change	Observations
Banana	Brown	None	Nothing changes, it still look the same.
Paper	White	None	Nothing changes, it still look the same.
Styrophone cup	White	None	Nothing changes, it still look the same.
Bread	Brown	None	Nothing changes, it still look the same.

Paper	Brown	Nothing change	Nothing changes, it still look the same.
Styrophone cup	White	Nothing change	Nothing changes, it still look the same.
Bread	Light Brown	It turned mushy	It melted and turned mushy and waterly.

Safely/Equipment- Science

For this blog post, I'm going to talk about safely when you are in a science lab. Here are 10 step that you should not do in a science lab and 7 equipment you use in a science lab.I hope you follower those step when you are in a science lab. Thank you

1. No running in the sciences lab

2. Put your bags under your desk 

3. follow the things that the teacher ask you to do.

4. If you spill something you should tell your teacher immediately.

5. You should wash your hand everything acitvity you do.

6. Never taste or drink the chemcials. 

7. You should know what you are doing before the teacher since you away.

8. Follow the  instructions given to you by the teache.

9. You must never eat or drink in the sciences lab.

The equipment in the sciences lab.

2040 Documentary- Science

Today in period 3, we watched a Documentary about Solar and Climate Change. We watched the Documentary with Ts, Mt and Ds. The Documentary was very long because it took the whole period up but it was worth it because there was all of information about Climate Change and Solar. What surprised me in the Documentary was the Damon Gameau because he knew mostly everything about Solar and Climate Change and he was the mostly only one talking in the Documentary.

What Damon Gameau did was travel all around the world and talked to other people and ask what they want future and how they prevent global warming. Bangledesh was very smart, what they did was they used this boz. What it did was it collect the solar engry and then it would save it. Then if the owners wanted to they could share it to others that needed the power. Damon Gameau went to lots of countires.

At night when they needed power, they would use the box and use the power because what the box did was it saved the power and then when they needed if they could use it.
