Activity Preparation
Locate an area outside of the school, preferably where an asphalt or concrete walkway is adjacent to a plot of grass. Note: If the ground is saturated due to recent rains or watering, the demonstration will not work correctly. Plan this demonstration for a day when water will soak into the ground.
Fill watering cans with equal amounts of water to take outside.
Review the included PowerPoint prior to using it as part of the lesson. It will provide students with information from #4 of the Discussion section.
