There are three separate lessons within this resource that can be used together, or that can each stand alone. In the first, five simple activities allow junior scientists to examine the amazing properties of water. In the second, they compare the strength of potato chips with ridges and without to demonstrate why seashells might have ridges. The third activity gets learners thinking about what objects might be unsafe to pick up when beach combing. Geared toward younger scientists, these lessons could be used in an ocean unit or prior to a field trip to the shore.
