Weighing In

Third graders predict and experiment to discover the amount of force exerted by a stretched elastic band. They construct a spreadsheet and make a bar graph showing the results of their experiment.

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,...

Students experiment with force and motion. In this force and motion lesson plan, students test gravity using a variety of objects. Students rotate through a series of stations which use force, motion, friction, and inclines. Students...

Young scholars apply their knowledge of friction, drag, mass and gravity as they design, build, and test mini-bobsleds.

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...

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,...

How can you keep a ball from falling out of a jar if the jar is upside down? Watch the ZOOM cast use centripetal force to meet this challenge. [2:54]

How does the absence of gravity affect the human body? The skeletal system, circulatory system, and the sense of balance are all impacted. With a very casual tone, an astronaut explains the changes to these body systems and also an...

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

Students watch experiments to define gravity and what gravity's function. In this gravity lesson, students watch video segments about experiments conducted with two objects to see what gravity does with different masses.
