Each person must complete TWO or THREE of the following, and print the summary at the end. Each table needs to divide up the quizzes so that there will be at least two samples of each per table. Doing these quizzes should take you about 15 minutes.
Carbon #1
Carbon #2
Carbon #3
Carbon #4
Now, we need to find out about the Carbon cycle. Print off one copy of each of the following documents and bring back to your table. Read and share the information with one another, underlining the top facts in the article (underline no more than 5 sentences). As a table, highlight with a yellow marker anything your group decides is an OPINION, and not supported by evidence.
Article 1
Article 2
Article 3
Article 4
Article 5
Article 6
Take a look at your group's carbon footprint data, and personally decide the FIVE most important things that you can do at this point to reduce your carbon footprint. Each person should make a poster that has these FIVE things listed, as well as graphics to support your choices.
Hand in the group readings and the posters at the end of the hour. Paperclip the material for each table.

Vocabulary review on Alternative Energy QUIZ MOVED TO THURSDAY
Active Solar: using solar energy collected through a panel to generate electricity
Wind Energy: Harnessing the power of convective heat transfer to power a device to create electricity or energy
Thermal mass: materials designed to warm up from the sun's radiation, and then to cool into the air when the sun is not present 
Multiple Pane Windows: Windows that protect against heat loss because of an air space between the glass layers.Annual Cost factor: the amount of money saved by using appropriate insulation. Click here
Alternative Energy: Any type of energy that does not take fossil fuels, and minimizes the impact on the environment
Heat Loss: Locations in a home where the energy loss can be found
Radiant Heat transfer: moving heat from one location to another without touching.Monday, September 21, 2009
You Decide
Your parents, impressed with your new-found knowledge in the area of alternative energy, want to know which technology would be best for your home and your budget.
1. Based on your classroom knowledge, define passive solar, active solar, and wind energy. Draw a sketch to accompany each definition.
2. Draw a sketch of your home, noting where the windows are in relationship to N, S, E, or W.
3. List three pieces of evidence for the technology you choose. This is based on work done in class.
4. Find the cost of the technology you choose. This is based on Internet research. At least 3 URLs must be listed, along with the cost at each website.
Finally, check out EcoGeek to find two additional pieces of evidence that support your idea. Make certain you reference the title of the blog post, or the URL where you found the information.
This is due on MONDAY, 9/28, at the beginning of class.
Solar Ovens: passive solar technology
Your goal is to design, with ONE partner, the best solar cooker for here in Iowa. You may modify one of the following designs:
Pizza box cooker
Open Box cooker
CD cooker
Pringles can cooker
Pop bottle cooker
Remember, these designs are only starting points. You can add insulation, reflective foil, or black paint to make things better. You will have 60 minutes in class on Tuesday to design these. Ovens are due at the start of class on Thursday. You will heat a) a thermometer and b) a marshmallow OR b) water to test their effectiveness.
