Pulleys and Force

I would weigh less on the moon? Send me there, then! On the top of the first page, a cartoon image demonstrates the difference between Earth and the moon. It then goes on to describe weight and mass and provides five practice problems...

Get the ball rolling with this upper-elementary science unit on forces and motion. Offering over three weeks of physical science lessons, this resource is a great way to engage the class in learning about simple machines, friction,...

Attracted class members to an activity-packed journey through the science behind the invisible forces at work all around us. From jump rope generators to junkyard wars, there's never a dull moment when eighth grade physics scholars...

Get things moving with this elementary science unit on simple machines. Through a series of nine lessons including teacher demonstrations, hands-on activities, and science experiments, young scientists learn about forces, motion,...

Take a deep breath and have your class construct working models of a lung! Using 500ml plastic bottles as the chest cavity, and balloons for the lung and the diaphragm, learners work in groups to make a model. The models help them to...

In this solar system instructional activity, students complete 13 multiple-choice questions to demonstrate their knowledge of the solar system.

What is mu? Emerging scientists explore the coefficient of sliding friction, or mu, and apply its concepts as they complete activities in the interesting lesson. They measure the sliding friction between soles of their own athletic shoes...

Students explore the solar system.  In this solar system science lesson, students choose 3 out of 12 centers to visit, each of which contains an activity related to the planets. The station activities are designed to address...

Demonstrate lift to the class that is studying aerodynamics. In the stream of air produced by a blow dryer, little physicists place a wad of tissue paper and a spherical figure to compare. Or, if you have a vacuum cleaner and beach ball,...

A video and a short multiple-choice quiz on the topic of gravity and inertia, and how they work together to keep objects from floating off into space.
