Pre Lab
This week's lab will explore electrostatic charges, charge interactions, conductors, and insulators. We will explore these ideas qualitatively, making observations of various phenomena in lab.
Electric charge is the fundamental property of an object that determines how that object will interact with other objects containing charge. We describe charge as being positive or negative as we will discuss in lab. A conductor is a substance in which charges can move freely, while in an insulator charges tend to be more tightly bound.
In the lab this week we will explore these ideas by observing several phenomena highlighting the interactions between charges. We will also build an electroscope and make predictions using an interactive computer simulation. Prior to lab please complete the following:
