|Name of Activity||Intro To Static Eelectricity with Balloons|
|Keywords||static, electricity, balloon|
|Grade Level||4, 5|
|Time||1 Hour Total|
|Brief Description||Students will 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:||Students at the end of the lesson should understand how electrons are transferred to objects due to friction, and how the addition of electrons affects repulsion and attraction to other objects.|
|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, electrons, protons, attraction, and repulsion. It is key to explain that only electrons are transferred, and when they are transferred through friction it makes the balloon more negative, thus making other objects attracted to it. This effect only lasts for a short amount of time since only a few electrons are transferred to the balloon. Drawing diagrams of more negative and more positive ends of objects helps to explain this.
It might also be helpful to give real life example such as: static shock due to rubbing socks against a carpet.
|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.|
