• Cups small. (x4)
• Water.
• Tinfoil.
• 1 sheet of black paper.
• 2 sheet oh white paper.
• Thermometer.
• 1 large cup.

Steps

• Get all the materials.

• Then put the cups on two 2 different white pieces of paper (1has a big plastic cup on the small cup.) Put 1 on a piece of a black piece of paper. And the last one on a piece of tinfoil.
• Use the sun or a heat lamp on the cups with the water in them.
• When you have done that use the thermometer and get the temperature of the
• Water.

Which surface conducts/attracts the most heat?

Time + temperature	Cup 1 White paper	Cup 2 White paper+ plastic.	Cup 3 Black paper	Cup 4 Tinfoil
0	15	13	12	13
40 minutes	17	16	24	22
55 minutes	18	17	23	22
70  minutes

Conclusion

When you leave them for 40 min the water of the white paper was at 15 and it went up to 17 then 15 min later it went to 18. The white paper and cup on top was at 13 and went up to 16 then 15 min later it was 17. The black paper was at 12 and went up to 24 then it is at 23. The tinfoil was 13 and went up to 22 then it was at 22.

2.   Not use gas 
3.   Not use oil 
4. Put rubbish in the rubbish bin

AT WHAT RATES DO DIFFERENT ITEMS DECOMPOSE?

MY INVESTIGATION.

Choose 5 items from the list and investigate them. 

• Paper 
• Leaves 
• Glass bottles 
• Plastic bottle 
• Plastic bags 

Paper 

It takes 2 to 4 week to break down. It give as air 

Step 1: The recipe. We use sand, limestone, soda ash and recycled glass(cullet) in our glass recipe. 

Step 2: Melting. 

Step 3: Molten Glass Separation. 

Step 4: Forming & Moulding. 

Step 5: Annealing. 

Step 6: Inspection.

Step 7: Packing & Shipping. 

Step 8: Recycling.

Leaves 

1 to 3 months to break down. It make compost.

Step 1 trees

Step 2 water 

Step 3 sunlight 

Glass bottles 

It takes 500 to 1000 years to break down . They make roads.

Step 1: The recipe. We use sand, limestone, soda ash and recycled glass(cullet) in our glass recipe. 

Step 2: Melting.

Step 3: Molten Glass Separation. 

Step 4: Forming & Moulding. 

Step 5: Annealing. 

Step 6: Inspection. 

Step 7: Packing & Shipping.

Step 8: Recycling.

Plastic bottles 

It takes 400 to 500 year to break down .People make roads and clothes.

How to make plastic bags vid.

Plastic bags 

It takes 10 to 20 years to break down. The bags pollute the earth.

• Bike and walk some more.

sci 2019 term 2 and 3

Findings:

	The H2O Cycle: Bag 1	CO2 Water Cycle: Bag 2 Acid	Desit Water Cycle Bag 3
Does it cycle?	Yes is dose	Yes it does	Yes it does
Amount of Water	2	2	2
Acidity	1	2	1

Other comments:

1. The water cycled in Bag 1
2. The water formed small drops in Bag 1.
3. The water was not acidic in bag 1.

1. The water cycled in Bag 2.
2. The water formed small drops in Bag 2.
3. The water was acidic in bag 2.

1. The water cycled in Bag 3.
2. The water formed small drops in Bag 3.
3. The water was not acidic in bag 3.

Conclusion:

As you said they worked and bags 1 and 3 didn’t have acidic. They were cycling and they made the water rise. They made some bubble.

cycle

AIM: TO LOOK AT THE WATER CYCLE AND HOW CLIMATE CHANGE IS AFFECTING IT.

Scientific words

• Evaporation. When water is heated by radiant energy it turns into water vapor.
• Transpiration. Evaporation from plants.
• Condensation. When water vapor cools, molecules join together and form clouds.
• Precipitation. When clouds get heavy the water falls as rain, sleet, hail, or snow.
• Acidification The action or process of making or becoming acidic.

THE WATER CYCLE EXPERIMENT

Bag 1: Normal Water cycle

Bag 2: Water cycle with CO2 added: like Oceans in climate change

Bag 3: Water cycle with ice added: like Antarctica in climate change

Material:

1.  Zip lock plastic bag 

2.  Vivid 
3.  Cup of water
4.   2 blue drops of food coloring 

Two Images:

Findings:

I expect to find the water dripping on side of the bag. 

Conclusion:

The water cycle starts with the sun.  It goes to the rain then the trees then it goes to the clouds. Then it will start raining then it will start rotating again.

Material:

1. Soda water 
2. Litmispaper

3.  Zip lock plastic bag 

4.  Vivid 
5.  Cup of water
6.   2 blue drops of food coloring 

 

Steps:

1.  Get the bag
2.  Get a vivid
3. Get litmus paper
4.  Draw on the bag 
5.  Get the soda water 
6. Put soda water in the bag
7. Put food coloring in bag 
8. Put the litmispaper in the bag 
9. Zip the bag up 
10. Put bag on the window
    

Poetry

My class has been with Mr Scott for 6 to 8 weeks. We have been working on poems for 4 to 5 weeks at most. I have done these two poems hope you like them. the first is a haiku poem and the second is a free verse poem. 

I chose a haiku poem because I really like how it was from a different place and I liked how it was laid out.

 

The Monarch

5 There was a monarch

      .  . .    . .

7 She is happy and joyful

     . .     . . .        . .

5 Her wings were rainbow

    .    .  . .   .

I choose a free verse poem because I liked how you can make it up and there no rules and I like how it is laid out to.

There is a beautiful pug

she likes to play in the mud

she eats pears and

she like to brush her hair

she is so cool

she watches people play in the pool

she is really nice but she eats rice

she is so cuddly

she is a bit muddy with her things

she is funny she like to eat bunnies.

I like poetry because I like how I can explain my feelings about the thing or the object instead of telling it to people I can write it in a poem.

what are we doing to the earth
