2D Motion

The stage is set for you to guide future physicists through three forceful activities about motion. In the first, learners experiment with rolling carts to discover how objects interact. In the second, they inspect images of an object in...

In this sixth of seven activities revolving around the concept of density, physical science fans figure out if anything can be done to change the density of an object. Demonstrate by placing a can of regular and a can of diet soda into a...

Do you need some new ideas for teaching Newton's Laws of Motion? This series of activities will spring your curriculum to life! Choose from five activities to demonstrate or have your science stars perform. As a result, they will have...

There's more to fluids than meet the eye—they include gases, liquids, and polymers, too! Scholars complete three hands-on activities exploring different properties of fluids. They explore viscosity by measuring the resistance, or...

Ride the wave to an understanding of refraction! The first in a series of two inquiry-based lessons challenges learners to create transverse waves with two different types of springs. As their wave hits an object, they observe the change...

Though an alternative method is suggested, the best way to carry out this investigation is with the use of a computer-interfaced motion detector. Physics fanatics hang a mass on the end of a spring and analyze its motion verbally,...

How is tug of war related to pushing a refrigerator? Here's a simulation connects these two activities with Newton's First Law of Motion. Four different simulations allow scholars to explore net force with tug of war, motion with pushing...

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.

Pupils apply their knowledge of the shape and slope of graphs to interpret the motion of an object.  Three levels of difficulty provide plenty of practice with support thanks to the "Help Me!" button offered with each question.

Hit a bullseye with an engaging presentation about the components of projectile motion. Viewers see how horizontal and vertical motion combine to create the parabolic path of projectile motion.
