In this activity about the property of water (page 6 of the PDF), learners use a coin to demonstrate cohesion between water molecules, exploring the molecular forces that allow water molecules to "stick" together. Although this activity was created as a pre-visit for a workshop about weather, it also makes an excellent stand-alone activity!
