Newton Car
If a car gets heavier, it goes farther? By running an activity several times, teams experience Newton's Second Law of Motion. The teams vary the amount of weight they catapult off a wooden block car and record the distance the car...
Curated OER
UFOs
Students, in groups, construct a catapult. Then they conduct a series of experiments by catapulting a marshmallow, using different lengths of spoons, across the room. They predict, measure, and record the measured distance on a worksheet.
Curated OER
Simple Machines, Odd Machines
Students recognize and identify common objects that can be used as a lever. In this simple machines instructional activity, students experiment with materials to design and construct a machine that uses a lever. Students also design and...

Science: Motion Commotion
Students examine Newton's three laws of motion to discover what causes it and how it changes. They conduct motion experiments by building catapults and constructing balloon rockets. Finally, they conduct peer studies correlating...
Curated OER
Fling It
Students investigate the best design using technology. In this science activity, students construct a freestanding object with specific materials to be able to shoot a ping pong ball and a marshmallow. They have to adjust and discuss...
Curated OER
Angling for Distance
Explore the concept of projectile distance through determining the angle that will provide the maximum distance of a launched projectile. Students launch baseballs on a football field and video tape the path of the ball.
Curated OER
Exploring Levers
Students examine the parts of a lever system and their functions. In this simple machines lesson students study the different classes of levers and what they are used for.
