Intro to Static Electricity
|Name of Activity||Intro to Static Electricity||Author||STOMP||Keywords||static, electicity||Subject||Non-LEGO||Grade Level||4||Time||1 Hour Total||Brief Description||Students use plastic balls and/or balloons to attempt to pick up various objects using static electricity.||Lesson Objectives:||Introduce students to the concepts of electricity and static electricity using a combination of discussion and a hands-on activity.||Materials Needed:||-Plastic balls and/or balloons (Note: Double-check before entering the classroom that these objects WILL actually pick up materials.)|
-Various light items such as scraps of paper, salt, flour, glitter, string, etc.
|Necessary Background||Students should be given background regarding electricity and static electricity. Some vocabulary that may be helpful include: charge, electron, attract, repel, conductor, and insulator. Students should brainstorm various materials that would be considered either conductors or insulators.||Procedure|
- Arrange students in pairs or groups, depending on availability of materials.
- Provide students with paper to keep track of their observations.
- Allow each pair/group to test several types of materials.
- Discuss with class why some materials can be picked up and others cannot. Discuss what is physically causing the materials to be attracted to the plastic balls/balloons.
|Extensions:||If your classroom happens to have a sink, an interesting demonstration could be showing how static electricity will affect a stream of water (it will repel it). You could also mimic this activity with a funnel or some type of vessel with a small hole and a bucket of some kind to catch the water as it falls.||Online Reference(s)||https://docs.google.com/presentation/d/19q_4mnZJp3yC-uBRxm3JQvwNopygVbC7tZB5dwTGCoM/edit?usp=sharing||Umbrella Unit/Curriculum (if applicable)||Electricity & Magnetism|
