How can we help kids visualize the charges that cause static forces? This is the question I wrestled with for a while before developing this model. I love that only the negative electrons can move – I also love that students can easily see when charges are balanced and when they’re not. This activity builds on the previous two activities Charged Up 1: Tracking Static Forces
(free) and Charged Up 2: Tracking Static Forces
. This is the most challenging of the three as it involves induction.
Answer Keys and Teacher Notes
are there to address most questions and issues that might arise in this study—you shouldn’t have to do outside research unless you want to.
This is the second of three related resources.
★ Charged Up 1: Tracking Static Forces
★ Charged Up 2: Tracking Static Forces
• Typically only electrons leave their atoms.
• Electrons are negatively charged; protons are positively charged
• Electrons and protons create the charges behind electrostatic forces.
• Items can be charged at a distance.

Extensive teacher notes address the many questions that come up. You shouldn’t have to do outside research on this topic unless you want to.
