The force of attraction or repulsion between charged particles is called electric force. The
strength of the electric force depends on several factors. It depends on how many electrons or protons there are. It also depends on the distance between the charged particles. How do you think the force will change if you increase or decrease the distance? ([ck12.org - Electric Charge and Electric Force](https://www.ck12.org/book/CK-12-Physical-Science-Concepts-For-Middle-School/section/5.61/)). One of the applied projects will be to create a way to test different batteries to see if they are still any good using a micro:bit.
Give students real world experience with coding, collecting data, analyzing data, and reporting results using [MakeCode’s](https://makecode.com) block programming and a [micro:bit](http://microbit.org) with its sensors.
Students need to have a basic knowledge of how to code using block style programming (micro:bit using the Windows 10 MakeCode app) and download a program to a @boardname@.
