1. Galileo and the Leaning Tower of Pisa
The chapter Highlight talks about Galileo and the "experiments" that he may or may not have conducted. Follow the recommended links at http://www.pbs.org/wgbh/nova/pisa/galileo.html to do simulations of three experiments. After completing experiments 1 and 2, what do you find out about gravity? And what is the solution to experiment 3?

After You Answer the Questions
You'll notice that Experiments 1
http://www.pbs.org/wgbh/nova/pisa/exp1wave.html and 2 http://www.pbs.org/wgbh/nova/pisa/exp2wave.html are pretty easy. However, Experiment 3 http://www.pbs.org/wgbh/nova/pisa/exp3p1.html does require some calculation.

2. Vectors and Projectiles: Can You Help the Zookeeper with His Monkey?
Follow the recommended links (below) to expand on your knowledge of vectors and projectiles by considering the zookeeper's dilemma. At the end of the online exercise, you'll notice four links for information on physical descriptions of motion. Click on the first (acceleration due to gravity), third (projectiles), and fourth (characteristics of a projectile's trajectory) and briefly summarize what was stated (in no more than a sentence or two). How does this relate to what you learned about projectile motion in the text?
