In this experiment, students measure the area of a dime using methods similar to those used by scientists to measure the size of atoms. When working with atoms, scientists sometimes have to invent new ways of doing simple things. For instance, scientists can't use a ruler to measure the size of an atom's nucleus. This activity shows how ratios can be used to calculate the area covered by an object.

The instructions provided here are of devices that have been built for Jefferson Lab's Science Education program. The difficulty of construction varies from project to project. Anyone attempting to construct these devices needs to know and understand how to safely operate the tools required to construct them. If you do not know how to properly operate power tools or a soldering iron, you should not attempt to build any of these devices.

Students use a Although atoms contain both negatively and positively charged particles, they do so in equal amounts and carry no net charge. This balance can be temporarily disrupted by rubbing one material against another. One device, known as a Van de Graaff generator, uses a fast moving rubber belt to charge a metallic dome to nearly 200,000 Volts. This activity uses a Van de Graaff generator to study the behavior of electrical charges.

Developed for use with Jefferson Lab's Go Far Cars experiment, this simple ramp can easily be set to four different height settings. The ramp settings are uniformly spaced, so the amount of gravitational potential energy given to an object at the top of the ramp increases by a constant amount as the ramp is placed at higher settings. The instructions provided here are of devices that have been built for Jefferson Lab's Science Education program. The difficulty of construction varies from project to project. Anyone attempting to construct these devices needs to know and understand how to safely operate the tools required to construct them. If you do not know how to properly operate power tools or a soldering iron, you should not attempt to build any of these devices.
