Test Post: Who Is Hiding on a Penny?

As Presidents' Day approaches, social studies activities abound. But you may ask yourself, "What kind of science activities can I teach my students that are related to Presidents' Day?" Here is one idea: Invite your students to use lemon juice-soaked cotton swabs to clean a penny. To add a little fun, tell them that they are detectives using a secret potion that helps to reveal clues. Give each child a magnifying glass (remember, they're detectives, right?). Encourage them to look for details on both sides of the penny. Guide children in recording their findings using drawings and/or words.
