Cookie Erosion- this is an alternative to our "fake rain" experiment. It might actually teach weathering and erosion better. On Tuesday we could do the 1 minute tests, and Wednesday do the 5 minute tests. This would have more information for the math graphs lessons too!
"After reading a few books on wind, we did a fun experiment. We used a fan to see what objects would move in the "wind" and what objects wouldn't. First, students made a prediction and then we tested our predictions. Students loved being scientists and followed along very well! Here is the table that I used for this. I did this activity with the whole class gathered around the fan. The kids used clip boards to write."
