1. Research Project An exploratory study Modeling environmental effects in the classroom

2. Environmental Themes: Climate Change/Climate Differences  Global Warming  CO 2 increase  Insolation  Water  Acid Rain  Ozone  Geologic differences

3. Global Warming How do we measure it?

4. History of Change in the U.S. It’s not the same everywhere

5. Carbon Dioxide Questions of fairness

6. Long-term Temperature Change The Earth was much warmer in the past.

7. Volcanoes, El Niño & Global Warming El Niño index Non-anthropogenic sources

8. Precipitation Change With climate change precipitation patterns change

9. Acid Rain The problems occur far away from the source

10. Ozone Pollutants are causing changes in trace molecules

11. Local Geology Do we put the lands to their best use?

12. Generating Experimental Ideas The Four Question Strategy Cothron, Giese, & Rezba. Students and Research. Kendall/Hunt 1989 1. What materials are readily available for conducting experiments on (plants)? Soils, Water, Radish Plants & Seeds, Light, Carbon Dioxide, Containers, … 2. How do (plants) act? Plants grow.

13. The Four Question Strategy 3. How can you change the set of (plant) materials to affect the action? Earth—type —compaction Air—composition —temperature 4. How can you measure or describe the response of (plants) to the change? Measure the height, Number that germinate, Count the number of leaves, Health of plant Water—method of application —amount —acidity Fire—amount of light —intensity of light 5. How does your experiment model the environment?
