3 Kids doing the Experiment to see How Rain Affects Soil.
Each group gets a 1/2 hour to cooperatively work through the procedures. They make predictions and do an analysis of the results once completed. During the experiment, they made observations and recorded the facts. It is a very good process. And, believe it or not-- the total time is 3 and 1/2 hours to get all of them to be able to experience this!
