Decomposition

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

Hypothesis: Bananas, white stylophone, paper, and bread. I think the bread will decompose the fastest.

Materials:

• Test tubes X4

• Test tube holder.
• White stylophone.
• Paper.
• Bread.
• Bananas.
• Water.

Steps:

1. Set up a test tube holder.
2. Put 4 test tubes in the holder.
3. Put Bread in one tube.
4. Put paper in one tube.
5. Put white stylophone in one tube.
6. Put Bananas in one tube,

Findings:

3 weeks	Colour	Change	Observations
Banana	Yellow	Black/brown	Got fluffy on it. steam is brown. juice out. Stinks.
Paper	Brown	Brown	It looks exactly the same 3 weeks ago.
Stylophone cup	White	White	It looks exactly the same 3 weeks ago
Bread	White/Brown	Black/White	Changed form. black piece in it. A lot of water at the bottom.

Conclusion:

Maths DLO

This week for maths we have been working on divided abys so we had to make a DLO for another person our teacher chose for us. I got a Paea as my partner so I made him a math DLO that he had to answer. So this is my math DLO hope you like it and if you want to solve it then you can, you can ask me for the answer in the comments.

   

Solar Energy

Aim: To learn about how solar energy is used.

Hypothesis. I think that black will attract the most heat.

Materials:

1. 3 cups black, white and clear
2. Thermal.
3. Paper, Tinfoil, and black paper.

Steps:

1. Get the materials.
2. Put tinfoil around the clear cup.
3. Put the tinfoil cup on tinfoil.
4. Put black stuff around the black cup.
5. Put the black cup on black paper.
6. Put the white cup on white paper.
7. Put a light in front of all the cups.
8. Check the temperature every 15 minutes.

Findings:

That I was right, black attracts the most heat.

Time	Cup 1 White	Cup 2 Black	Cup 3 Tinfoil
0	16	16	16
15	20	21	20
30	20	21	21
45	21	25	21

Science (Climate chaos)

Today in science we were learning about the water cycle so we were given 10 shapes that had words in it that are about the water cycle. We had to put them together but it had to connect with the one it's connected to are you will have to change it around. The 10 words on the shapes were Evaporation, Condensation, Transpiration, Water cycle, Water vapor, Precipitation, Acid rain, Carbon Dioxide, Climate change, and Hurricanes. We had to connect all those on a piece of yellow paper and when we were finished we had to write on the paper why they connect. So we had arrows going to that shape why it connects to that other shape next to it here is a picture of the paper me and my group made.

How they work together  
Evaporation, Condensation, Transpiration, Water cycle, Water vapor, Precipitation, Acid rain, Carbon Dioxide, Climate change, and Hurricanes. work with the water cycle.

Evaporation, Condensation, Transpiration, Water cycle and, Water vapor work together because they all go with the water like there a part of the water cycle.

Precipitation and Acid rain connect because of Precipitation is rainfall and acid rain is rain that why they are together.

Carbon Dioxide, Climate change, and Hurricanes work together because they are all a part of the climate change.
