__Science Extension __ By: Sugar Mama [Holly Harrington] My notes on global warming: *not all the sun's light rays hit Earth *the greenhouse effect is a natural process *the greenhouse gases absorb the light from the sun's rays *the greenhouse gases are increasing due to us burning the fossil fuels *I am enjoying the subject alot so far *I have never explored the subject of global warming and I thought it would be hard, but is really easy to catch on to

This is my Step 2 PowerPoint:

3 Reasons reflection: I looked on the first website Mr.Maurer posted on step 3. I easily found more than 3 reasons that global warming is caused. I believe my reasons were good and showed that to me 89% of global warming is created by humans.

Is Global Warming Real Reflection: [this stuff was the stuff that really stuck out to me] *Earth's averege temp. has risen 1 degree more in past century *2 times that in Arctic *what does fluctuated mean?[this ? is bothering me because i can't understand the sentence] *temp. has been creeping upward *trees store info. of past climate *trees grow rings for every year they live *scientists collect info. from sediment layers going back millions of years ago *I don't get what to do on the interactive map *the map is confusing me *in the second National Geographic article I found it interesting how polar bears are getting skinnier *poor polar bears it is not their fault that their homes are melting *I think it is humans fault that global warming is happening because we are the ones burning fossil fuels and powering cars with energy sources that let off gases that are causing air pollution and global warming. WE ARE THE ONES HURTING POLAR BEARS!!!!!!!!!!!!

3 Steps to Reduce Global Warming and step 5: *Burn Trash *Nuclear Energy *Pulling water from air[I am using this one] *the stopglobalwarming.com website was interesting

Step 6: I am doing my project on pulling water from the air to power cars. This will stop all the air pollution from cars and global warming. We could do this if we all worked together to create machines to do these things. Then the world would be ridden of all global warming. My project is done and I am ready to present my project for all to see. For my project I made a powerpoint. I found some very interesting facts about things cars do. I am happy that I chose this subject for my project.
