Catching the sun movie

Materials:

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

Steps

• Get all the materials.
• Lay things out.
• Put water in the little cups.
• Put the big cup on a smaller cup that has water in the cup.
• 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	17	18	22	22

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.

Wind speed - Making an anemometer.

MATERIALS 

1. PENCIL.
2. TAPE.
3. PIN.
4. 4 STRAWS (2 CARDBOARD AND 2 PLASTIC)
5. 4 WHITE CUPS. 

STEPS

1.   Get 4 white cups.
2. Put 2 holes in each cup.
3.  Put the straw that you made in the holes that are in the cup.
4.   Put a cardboard straw and a plastic straw together (by putting the cardboard straw in a side of a plastic straw)

Once you have made an anemometer we are going to record the wind speed.

Group size: 5

You will need:

Anemometer (above) 

Roles:

• Timekeeper
• Counter
• Recorder
• Anemometer Manager
• Wind generator

1. Mount the anemometer in a place that has full access to the wind from all directions.
2. When the timekeeper says "Go", the counter in each group will count how many times the marked cup passes them in one minute and write it down.
3. If possible, repeat the above step four (4) times and record the average number of spins on the chart.

FINDINGS

• Record how many times it spins using the table below.

You will need to create the wind yourself by blowing. Get 4 different wind speeds by blowing.

You will need to time them and count the number of spins.

• Can you make a statement connecting the number of spins of your anemometer and the speed of the wind? 

CONCLUSION:

Hurumanu - Science - Recycling

Aim: To learn practical ways of recycling so that we can make our world a better place.

The Zero Waste Climate Solution movie

How can we prevent climate change by recycling these products?

Plastics:
Cycling or walking: You won't have to use your car and buy fuel for your car.
Paper: You don't have to cut more and more trees down.
Steel: You will be going to need to use coal if we burn all of the steel we have at the moment.

Video questions:

What is Zero Waste?
One of the quickest and the cheapest ways a community can immediately reduce climate impact. What can we do on the planet?

1.   Recycle.
2.  Reuse.
3.  Reduce.
4. Redesign.

What do we need to recycle?

1. Plastic - Bottle's, Straw's 
2. Paper.
3. Cardboard - Box's

What does recycling do?

cuts down more plastic that is on the land. and if we don't recycle things it kills our animals in the sea.

How much of our rubbish is food scraps?

What does soil due to carbon dioxide in the atmosphere?

What do we need to do?

1. Make People stop littering in the cities. 
2. Have Zero tolerance for littering.

What is a carbon footprint?

How can you make your Carbon Footprint smaller?

ENERGY SAVING TIPS FILM

Name 4 of the tips.

1.   Turn off the lights in a room if there isn't anyone in there.
2.  Turn off switch's if the device/machine isn't being used by someone

AT WHAT RATES DO DIFFERENT ITEMS DECOMPOSE?

MY INVESTIGATION.

Choose 5 items from the list and investigate them. 

Aluminum can.

Plastic 6 pack ring.

Plastic bottle.

Glass bottle.

Milk carton.
You need to answer three questions.

Name: Abby

1. How long do they take to decompose?

Aluminum can: 200 - 500 years.

Plastic bottle: 450 years

Glass bottle: 1 million years

Milk carton: 5 years

1. What resource/fossil fuel are they made from?

Aluminum can: 8% of Earth's crust.

Plastic 6 pack ring:

Plastic bottle:

Glass bottle:

Milk carton:

1. How is this resource recycled?
2. How does this object contribute to climate change?

I have three goals to try and achieve.

1. 
   

Science

Solo taxonomy.

1. Prestructural.
-no organisation.
-unconnected ideas.

2. Unistructural.
-one idea.
-shows how connected thoughts.

3. Multi Structural.
-2 or 3 ideas.
-slightly connectedness.


4. Relational.
-make links to other concepts.

5. Abstract.
-Bringing your ideas into other concepts.
