Aerodynamics: What Causes Lift? How does an airplane stay aloft when upside down? This media-rich essay from the NOVA Web site offers an explanation based on Newton's third law of motion.	6-12	HTML Interactive
Circular Motion In this interactive activity featuring videos adapted from the Rutgers PAER Group, observe examples of circular motion. Can you find a common reason why the objects and people presented move in a circle?	6-12	Flash Interactive
Energy Transfer in a Trebuchet On NOVA, a team of carpenters, timber framers, engineers, and historians recreate a medieval throwing machine called a trebuchet. This adapted video segment explores how understanding energy transfer informs their design.	6-12	QuickTime Video
Free-Falling and "Weightlessness" Discover the difference between free-falling and weightlessness in this interactive activity from the NOVA Web site.	6-12	Shockwave Interactive
Galileo: His Experiments This interactive activity from the NOVA Web site samples Galileo's experiments with falling objects, projectiles, inclined planes, and pendulums.	6-12	Flash Interactive
Galileo on the Moon Watch Apollo 15 astronaut David Scott perform Galileo's falling objects experiment on the Moon in this video segment from NASA.	3-12	QuickTime Video
Galileo's Inclined Plane How did Galileo figure out the mathematics of falling bodies? This video segment adapted from NOVA examines Galileo's work on motion.	6-12	QuickTime Video
Galileo's Thought Experiment How can Earth move through space without our feeling its motion? This video segment adapted from NOVA answers this question by dramatizing one of Galileo's thought experiments.	6-12	QuickTime Video
Galileo: Timeline of His Life This illustrated timeline from the NOVA Web site turns back the clock to the late 1500's to relive the dramatic life of one of the world's most renowned scientists.	6-12	HTML Document
Getting Airborne and Wing Design What makes an airplane fly? Discover the connection between Newton's third law of motion and flight in this interactive activity from the NOVA Web site.	6-12	Flash Interactive
Glass Breaking with Sound In this video adapted from the Encyclopedia of Physics Demonstrations, learn how a glass beaker vibrates at a specific frequency and how resonance can force it to shatter.	6-12	QuickTime Video
Hoover Dam and Hydroelectric Power How does a dam generate electricity and what are the environmental impacts of operating these mammoth structures? Find out in this video segment adapted from Building Big.	3-12	QuickTime Video
Masses and Springs In this interactive simulation adapted from the University of Colorado's Physics Education Technology project, hang various masses from different springs and see the kinetic, potential, and thermal energy of each spring system. You can even slow time or move your demonstration to another planet.	6-12	Flash Interactive
Momentum In this interactive activity adapted from Wake Forest University, observe the effect of mass on velocity and momentum in elastic and inelastic collisions.	8-12	Flash Interactive
Newton's Third Law of Motion: Astronauts in Outer Space In this video segment adapted from NOVA, NASA learns hard lessons from the first American attempt to do work while "walking" in space. The video also explores Newton's third law of motion.	3-12	QuickTime Video
Projectile Motion In this interactive simulation adapted from University of Colorado’s Physics Education Technology project, learn about projectile motion by firing various objects from a virtual cannon into the air. Experiment with the settings and try to hit a target.	6-12	Flash Interactive
