Aim: To look at the causes of climate change and how to prevent it.

Climate Change video; The Facts video

As you watch the video answer these questions:

What is our greatest threat in thousands of years?

How do we see climate change affecting the globe?

1.   Cars and trucks because gas is typing the hot air down on earth
2. Sustain the runs.
3.  The earth turns into mars 
4.   People have bomb fire and fire 

Coal 

Coal is a type of fuel like oil. There are four different types of the four types are Anthracite. Bituminous, Sub Bituminous and Lignite. People and plants are losing lives because the coal and oil. Coal contains sulfur and other elements it is really bad for you because you can stop or your lungs can have bad air in them you could lose your life. Over 90,000 people in the United States have jobs that uses coal people do not like coal because they are worried about what will happen in 100 years time to their grandkids this is where you can find coal but I don't think you should use coal it is really really bad for the earth and the people that live in the world. Here is all the places in the New United States Connecticut, Delaware, Illinois, Maine, Maryland, Massachusetts, Michigan, New Hampshire, New Jersey, New York, Ohio, Oregon, Pennsylvania and Texas. 

Write a paragraph and upload an image about each of these renewable energies.

Solar

Solar mean the earth is warming up from the sun and when it does the gas keep it down on the ground we use it to warm up pools and we use it to warm house solar is really good to uses

Wind

Wind makes power and electricity so we can have electricity.

Waves

Waves can help so we can drink and it helps as have electricity so we can help the earth and help with the gas problem.

Solar Energy

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

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.

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.

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.

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.
