The examples in this collection were contributed by participants at the 2007 Teacher Preparation Workshop at Carleton College in Northfield, MN. The activities are used by the contributors in their earth science courses for pre-service teachers to help these future teachers understand the science they will be asked to teach to their students.

Destruction of the Rainforest and Atmospheric Oxygen part of Activities
Pre-service Midle School teachers devised an experiment to test an assertion that destruction of the Brazilian Rainforest would lead to a serious drop in atmospheric oxygen. The experiment proved to be a failure, but opened other avenues of science learning and had a positive impact on their confidence in teaching inquiry-based science.
