In this activity, students use a Dual Range Force Sensor to measure the weight of pennies. They understand the difference between mass and weight. Students also determine the difference in weight of an object on the moon, Mars, Saturn,...

In this lesson design and build a structure out of spaghetti and mini marshmallows.

It's difficult at times for younger students to realize that air has mass. Matter is something that has volume (takes up space) and has mass (*can be weighed). Air does take up space, even if we can't see it, and air has weight, even if...

Students practice using scales like the one in a doctor's office. Five Gregs will drop on the scale to be weighed. Participants see how fast they can weigh the Gregs.

Students work as physicists to understand centripetal acceleration concepts. They also learn about a good robot design and the accelerometer sensor. They also learn about the relationship between centripetal acceleration and centripetal...

Manipulate the mass of a weight and the length of string in this interactive pendulum simulation. Change the speed, friction, and gravity to make the pendulum swing change as measurements are displayed on the screen. Younger students can...
