How can we tell whether an item is charged electrostatically? This super simple piece of apparatus is easy to make and use and will definitely intrigue your students. This is yet another example of induction (when a charged item attracts a neutral one). The concept is addressed and touched upon, though for a more thorough explanation, you'll want to check out one or two of the other activities in this series.,
Written instructions are designed to go straight into students hands so you can literally print and go— writing prompts help focus student writing and lab sheets are available for students who need more structure and support.
• Charged items attract neutral ones.
• Invisible charges can produce real forces.
• Electrostatic fields are non-contact forces.
paper, pencil, binder clip + some type of charged object like a charging rod, balloon, or Van de Graaff
This lab takes about 30 mins.
• Scaffolded writing prompts & lab reporting
