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


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. 

Hydro

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 +

Cup 1
White paper
Cup 2
White paper+ plastic.
Cup 3

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.

rubbish bin

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


How can we prevent climate change though recycling these products?
Plastics:   there lese is in the world.
Cycling or walking:  that there is no gas .
Paper: we have some more clean air.
Steel:  there is not that much gas.

Video questions:

What is Zero Waste?
 One of the quickest and cheapest ways a community can immediately reduce climate import.
What can we do on the planet?
  • Reuling 
  • Rensign 
  • Reuse 
  • Repair 
What do we need to recycle?
  • Bags
  • Clothes
  • Can 
  • bottles 
  • Paper 

What does recycling do?
  • Help the earth 
  • Make the earth cleaner 

How much of our rubbish is food scraps?
  • alot 

What does soil do to carbon dioxide in the atmosphere?
  • It kills the plant.
  • We don’t have much food.
  • We need food and we need more plant.

What is a carbon footprint?

How can you make your Carbon Footprint smaller?

ENERGY SAVING TIPS FILM

Name 4 of the tips.

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

AT WHAT RATES DO DIFFERENT ITEMS DECOMPOSE?

MY INVESTIGATION.

Image result for rates of decomposition
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.

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

Goals

  • Don’t leave the lights on .
  • Make sure I don’t use much gas .
  • Bike and walk some more.

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
