Get close up and personal with a drop of water to discover how the polarity of its molecules affect its behavior. Elementary hydrologists split and combine water droplets, and also compare them to drops of oil. Much neater than placing a piece of wax paper over the graph paper is inserting a piece of graph paper into a resealable plastic bag and zipping it shut. This two-in-one adjustment would be easier to handle, especially for primary learners.
