Curated OER
Centripetal Force
In order to investigate cetntripetal force and angular momentum, youngsters compare the motion of erasers hung from a string. It is not clear what type of Amish toy is needed in the warm up activity, so you may not be able to use it. The...

Playing With Science
Young scientists investigate the scientific concepts and principles that help make common toys such as hula hoops, yo-yos, slinkies, and silly putty work. As a class, they read "Backyard Rocket Science, Served Wet" to get a look behind...
Curated OER
Spin, Spin, Spin That Body!: Figure Skating, Physics, Science, Winter Sports, Olympics
Students learn the scientific principles of centripetal force through research and experimentation.
Curated OER
Laws of Motion
Students explore centrifugal and centripetal force. In this motion instructional activity, students expand on their knowledge of motion to study velocity, acceleration, and friction. Students examine multiple objects to demonstrate the...
Curated OER
Action-Reaction! Rocket
Young scholars construct a rocket from a balloon propelled along a guide string. They use this model to learn about Newton's three laws of motion, examining the effect of different forces on the motion of the rocket. They measure the...

MEASURING THE GRAVITATIONAL CONSTANT, G
Pupils study gravitational force an. In this gravitational force lesson students observe a demonstration.
Curated OER
Solar System
Eighth graders identify the basic concepts of celestial bodies. They discover the difference between perihelion and aphelion and demonstrate how the universe is expanding. They also discover how gravity and centrifugal force are...
Curated OER
A New "Spin" on Nuclear Energy
Pupils explain how the spin cycle of a washing machine operates. They explore other applications of the centrifuge by reading and discussing the article "Slender and Elegant, It Fuels the Bomb."
Curated OER
Circular Motion: Target Practice
Students demonstrate direction of velocity of an object in circular motion. They discuss the mathematical formula, and demonstrate the formula using a string, rubber stopper and a target.
