Weighing In

How do we interact with Earth? Scholars learn about the sun, Earth, moon, forces, gravity, and heat sources by reading a text and performing hands-on demonstrations. They also differentiate between living and non-living things using...

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,...

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,...

Explore gravity, force, and mass as some of the natural forces in the universe. Each slide provides information and examples that describe each concept. Learners are encouraged to throw a basket ball and a bean bag into the air to...

Sir Isaac Newton was the first person to recognize the concept of gravity. Here is a video that introduces learners to "think of gravity like the invisible super glue that holds our massive world together."

How can an astronaut escape Earth's gravitational pull in order to get to the moon? This is the focus question in a video that discusses the differences in the strengths of Earth's gravitational force and the moon's gravitational force.

May the force be with you! Learn how to present the content of PS2A, Forces and Motion, using the strategies in the video. With fun scenarios that include Angry Birds and toilet paper, demonstrating the relationship between force, mass,...

What a wonderful way to explore motion and forces! Learners design a catapult, after watching a video and discussing types of catapults. This is a comprehensive and complete lesson with links to supplementary resources.

Learners view a video and complete experiments with force and motion.  In this force and motion activity, students examine small pieces and how they affect the motion of a toy car.  Learners also experiment with sand paper,...

In this science fair project, investigate the effect of speed on the distance and height of the skateboard trick the "ollie". The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and...
