Global warming presentation

  1. 1. We define Global Warming as when the Earth’s temperature rises and heats up, which in turn causes changes in climate, and it makes the Earth warmer and affects the level of our water . 4th Grade at Chesterbrook Academy West Chester, PA School 15

  3. 3. It was difficult coming up with the definition as a group. Discussions were difficult because we didn’t always agree with each other since we had different definitions. It was hard to blend them all into one draft. Looking up information on line was tough because there was so much information online, and some websites didn’t work. 4th Grade at Chesterbrook Academy West Chester, PA School 15 3

  5. 5. The change of climate in PA can lead to hotter days in the summer or even at other times. Global Warming heats up the Earth and causes natural disasters, like melting ice caps, avalanches, floods, and tsunamis. Global warming actually makes water levels rise. It melts the polar ice caps, turning them into water. This affects animals, such as polar bears. Ice caps are breaking apart in Antarctica and animals have to adapt to the changes in the environment. It takes some animals a while to learn how to adapt to new climate changes. Other animals never adapt and die off. 4th Grade at Chesterbrook Academy West Chester, PA School 15 5

  8. 8. Coal is our number 1 way of making electricity in PA. Number 2 is Nuclear Power, and number 3 is natural gas and oil. These are all non renewable resources. Global warming is caused by burning coal, driving cars, or using other fossil fuels. The Earth has poles, the poles have ice, the ice melts into the sea, and the sea level rises. We also need to conserve water. When towns use lots of water, there won’t be a lot left. When coal runs into streams, there is a chemical reaction. This turns the water orange and it becomes polluted. Rivers can collapse if miners dig beneath them looking for coal or shale. Someday coal will become completely used up if we keep using it at this rate. Also, global warming is progressively getting worse. 8
  9. 9. In our state, Pennsylvania, we have the DEP. DEP stands for Department of Environmental Protection. The DEP works to protect our environment: the land, air, and water. The DEP encourages people to save electricity and use more renewable resources, like wind and solar power , and they also help people learn how to help our environment. Global warming is a natural process. We may not be able to completely stop it, but we can slow it down. The DEP’s goal, is to make everyone aware of the goal for slowing down Global Warming. The goal is to reduce the planet’s temperature by 2 degrees by 2020. 9
  10. 10. Pennsylvania is very well known for coal and steel production. We are using more coal than ever. The DEP wants to make sure we are conserving energy and using alternative resources. Some laws have been passed in PA to help with Global Warming. One of these laws states that alternative energy sources must make 80% of our electricity, like solar energy, wind energy, and hydroelectricity (water). 10

  12. 12. We, the fourth grade students of Chesterbrook Academy #15, worked as a group to come up with ideas to slow down global warming. Our Ideal Environmental Policy includes alternative energy sources, energy efficiency, and conservation ideas. We want to keep our environment clean and conserve energy. Alternative Energy- Our state requires that 18% of our energy comes from alternative energy sources, such as wind, water, and thermal. Solar panels should be placed on top of tall buildings and street lamps and traffic lights. Factories should try to filter their polluted air before it comes out of the smoke stacks. We would like to design a car that uses wind power as it moves to create energy to power itself, and solar power to create energy to use it at night. We think everyone in our state should pay 1 penny per check every year to support the production of our wind and solar powered car. 4th Grade at Chesterbrook Academy West Chester, PA School 15 12
  13. 13. Energy Efficiency- We want to improve the laws about energy usage. We can use energy efficient lights in our homes to save energy. We can also buy electric powered cars too. We can give free stuff with each purchase of an electric car, such as a free solar panel installation on your property, free coupons for restaurants and shops, or pay less money in taxes. Conservation- We can use reusable plastic shopping bags or by cloth ones because this would help our environment by making less waste. You can also turn off unused electronics, or unplug them too! Also, take shorter showers to conserve water. We can use the following ideas to conserve old items: turn an old milk jug into a bird feeder/terrarium; turn old egg cartons into planting pots or to hold paints; use aluminum cans as pencil holders; save water by using it wisely (ice cubes to feed plants); Reuse plastic water bottles. We believe we should do these things to save energy and to slow down global warming. 4th Grade at Chesterbrook Academy West Chester, PA School 15 13
  14. 14. We wrote a letter to our West Chester Mayor asking if she was a part of the Mayoral Climate Protection Agreement. Here is Mayor Comitta’s response: Thank you for your interest in climate change and what the Borough of West Chester is doing to reduce our carbon footprint. Signing up for the US Mayor Climate Protection Agreement is on my list of things to do, and your class’s request has moved it to the top of the list – thank you for reminding me! I have attached the Borough of West Chester’s agreement of purchasing wind-generated Renewable Energy Certificates to offset a portion of our electricity usage. Also, the Borough of West Chester has a BLUER (Borough Leaders United for Emission Reduction) committee which I have attached their Climate Action Plan for you to look over. 4th Grade at Chesterbrook Academy West Chester, PA School 15 14
  15. 15. Yes, according to the Mayor’s letter, West Chester is trying to use Wind Power to generate power for the city. There are even 16 special windmills at our nearby Aquarium. These windmills are special because they help to generate wind power even if the wind speed is as little as 5 miles per hour. However, in Downingtown, the mayor has not signed the US Mayor Climate Protection Agreement. He says: “I would be happy to though. You can look for my name the next time they update there list. Thank you for bringing this to my attention.” 4th Grade at Chesterbrook Academy West Chester, PA School 15 15
  16. 16. Yes? Why? No? Why not? ------------------ Zoe: Yes, I am happy that our mayor is getting interested in signing the petition. Paige: I am happy because our local policy will help slow down global warming by using wind power. Taylor: Yes, I am happy because our West Chester mayor is getting interested in signing the Mayor’s Petition and is putting it at the top of her to-do list. 4th Grade at Chesterbrook Academy West Chester, PA School 15 16
