Describing motion along a line
| Rating: | |
| Type: | Course Related Materials |
Abstract: Motion is vital to life, and to science. This unit will help you to understand why classical motion is probably the most fundamental part of physics. You will examine motion along a line and the ways in which such motion can be represented, through the use of graphs, equations and differential calculus.
Driving Through Geologic Time - An analogy
| Rating: | |
| Type: | Course Related Materials |
Abstract: This activity uses an analogy to illustrate the scale of geologic time and our limited view of the Earth's history. It relates the history of the Earth to a drive across the country. The drive is 4560 km (rough distance between Washington D.C. and Seattle), with 1 km equaling one million years of Earth's ... More »
