|Name of Activity||Intro To Static Eelectricity with Balloons|
|Keywords||static, electricity, balloon|
|Grade Level||4, 5|
|Time||1 Hour Total|
|Brief Description||Students are introduced to the concepts of positive andnegative charge, attraction, and repulsion. They use balloons to attempt to pick up various objects and then discuss as a group why certain objects stuck to the balloon while others did not.|
|Lesson Objectives:||To introduce students to the basics of static electricity – attraction, prepulsion, negative and positive charges, electrons and protons, and the transfer of electrons. The idea is to get students to use the tangible example of a charged balloon picking up an object in order to visualize what goes on with the transfer of electrons.|
|Materials Needed:||Balloons/plastic balls, flour, salt, string, glitter, pieces of paper, paperclips, trays or containers to hold all the objects, worksheet for students to keep track of their observations.|
|Preparation and Set Up:||Wihle one STOMP fellow prepares the materials for the students, the other fellow can go through a brief introductory lesson (powerpoint attached below).|
|Necessary Background||Students should be given background regarding electricity and static electricity. Some vocabulary that may be helpful include: charge, electron, attract, and repel. It might also be helpful to give real life example, like talking about how when you walk on a carpet with your socks, you sometimes get a shock when you touch a doorknob.|
|Procedure||1. Arrange students into pairs or groups depending on availability of materials. We did pairs but sitting in clusters of desks, which seemed to work well – that way, they could share materials and talk in small groups, but were also encouraged to discuss more in depth with their partner. 2. Provide students with paper to keep track of their observations (attached below). 3. Allow students to test their objects/materials. 4. 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 (negatively charged balloon repels electrons in objects, creating a net positive charge where balloon comes into contact with object).|
|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.
Additionally, if students have the necessary background information, bringing in conductors versus insulators into the discussion might be cool.
