In this collection of demonstrations, learners explore Newton's Laws of Motion.

In this astronomy activity (page 3 of the PDF), learners will examine the effects of gravity on a person’s pulse and explore how gravity can differ from planet to planet.

Groups of learners are provided with a generic car base and an egg. Their mission: design a device/enclosure to protect the egg on or in the car as it rolls down a ramp with increasing slopes.

In this activity, learners work in groups to determine the mass and volume of four samples: glass marbles, steel washers or nuts, pieces of pine wood, and pieces of PVC pipe.

In this demonstration, learners observe as a bottle is placed on a table with wooden hoop balanced on top and a pencil balanced on top of the hoop.

In this math lesson, learners analyze the density of liquids in order to explore linear functions.

Learners set up three different bowls, each with a different mass of oatmeal. Learners monitor the temperature of the oatmeal and find that larger masses take longer to cool.

In this physics activity, learners recreate Galileo's famous experiment, in which he dropped a heavy weight and a light weight from the top of the Leaning Tower of Pisa to show that both weights fall

In this activity, learners make a scale model of an atom to see how big or how small an atom is compared to its nucleus. Learners will realize that most of matter is just empty space!

In this lab activity, learners act as fellow scientists and colleagues of Isaac Newton. He has asked them to independently test his ideas on the nature of motion, in particular his 2nd Law.

In this online activity, learners build their own system of heavenly bodies and watch the gravitational ballet.

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

Learners construct a rocket from a balloon propelled along a guide string.

Learners build simple catapults and use them to launch cotton balls.

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this activity, learners are challenged to calculate their own weight on various planets using a scale and calculator. Older learners may be challenged to do so without using calculators.

In this physics activity, learners will explore buoyancy.

In this online activity, learners use a realistic mass and spring laboratory. They hang masses from springs and adjust the spring stiffness and damping.
