The pore spaces within, and the ability to conduct water of, earth materials are key factors in determining how groundwater moves below the surface of the ground. Students hypothesize about water flow in models which seem identical, but allow water to flow at different rates through their pore spaces. Professor Trout Professor Trout is an interactive computer program that quizzes children on their knowledge of fish. Rate of Flow Students will conduct an experiment in order to understand water velocity by timing the rate at which a series of objects travels down a flowing body of water. This will be related to renewable and non-renewable sources of energy.
Students use oral descriptions to make predictions, pose questions and relay their findings.
Rolling Through the Shed Students pretend to be drops of rain which, through precipitation, enter into the watershed. They move through a model watershed to see how water, in the air and on land, interacts with pollutants, soil and human development. Students use oral descriptions to pose questions, predict results and relay their observations. Students use oral descriptions to pose questions, predict results and relay their observations. Runoff or Recharge Using a model, students investigate the importance of vegetation in helping to fight against water erosion and the importance of microorganisms in recycling organic materials to maintain healthy soil.
