Kindergarten Lesson Plan

Student PSEA – Outreach to Teach Lesson PlanJumping Rice KrispiesObjectives:The student will be able to:- Define static electricity- Explain what happens to Rice Krispies due to static electricityStandard:3.2.2.B2: Explore and describe how different forms of energy cause changes.Materials: Balloon Plexiglas/wooden blocks Rice Krispies Wool clothProcedure:1. Ask: How many of you know what Rice Krispies are? Has anyone everseen Rice Krispies jump before? Raise your hand if you even think that ispossible. Raise your hand if that is the craziest think you have heard!Well, today I’m going to show you a way to make Rice Krispies jump.2. Split students into groups of 3-4.3. Explain to students that we will be exploring static electricity.Ask: Has anyone heard of static electricity before? Can anyone think of atime when they saw or felt static electricity? (Answers may vary. Commonanswers may be “getting shocked” when they touch someone/something,rubbing a balloon in his/her hair..)4. Students may first experiment with static by rubbing an inflated balloon inhis/her hair.Ask: What happened?

5. Experiment:a. Spread some Rice Krispies on the tabletop, and place woodenblock/plexiglas setup over top of the cereal.b. Charge the Plexiglas with static electricity by rubbing the woolagainst it.c. Watch as the static electricity attracts the Rice Krispies.d. Let each student try to rub the wool on top of the surface of thePlexiglas.e. Allow students to run their hand underneath the Plexiglas to see ifthey can feel the static.6. Explanation:a. Positive charges and negative charges attract each other, or like tobe together.i. You can use “little kid terms”: Do you have any best friendsthat you like to spend time with a lot? Mr. Positive and Mr.Negative are friends and like to do things together – they liketo be around each other!b. The wool is full of Mr. Positive and the Rice Krispies are full of Mr.Negative. When you rub the wool on the Plexiglas, it makes Mr.Negative jump up!c. Summary: These positive and negative charges are everywhere.They like to attract to each other. This is how electricity works.When you get “zapped”, it’s the electric charge jumping from you toanother surface – Mr. Positive and Mr. Negative just want to hangout!Closure: (Can be done in groups or with entire class)Did you have fun? What did you learn about static electricity today?Thank you for letting us come in to visit your class!
