A car propelled by the reaction between lemon juice and baking soda has more in common with rockets and jet aircraft than one might think. In this video segment adapted from ZOOM, two cast members demonstrate the power of rocket-propelled vehicles and how to exploit the force produced by the carbon dioxide gas. Grades 3-8.

Demonstrate the Bernoulli Principle using simple materials on a small or large scale. This resource includes two activities that allow learners to experience the Bernoulli Principle, in which an object is suspended in air by blowing down on it. Use this activity to explain how atomizers work and why windows are sometimes sucked out of their frames as two trains rush past each other.

Students will engage with one another to design, create, and build a mini golf course hole using recycled materials. Once completed, the students will need to explain how their hole works using scientific terminolgy such as force and gravity. This hands-on, fun, creative activity will serve as an assessment tool on what students understand about the concept of force and gravity.

In this video segment, the ZOOM cast is challenged to keep a ping pong ball in a funnel while the funnel is held upside down, seemingly defying gravity.

Explore the forces at work when you try to push a filing cabinet. Create an applied force and see the resulting friction force and total force acting on the cabinet. Charts show the forces, position, velocity, and acceleration vs. time. View a Free Body Diagram of all the forces (including gravitational and normal forces).

This activity was developed for6th grade classrooms studying the Solar System, though can probably be used in a variety of settings. Students will be able to: • Draw motion of planets, Moons and satellites. • Draw diagrams to show how gravity is the force that controls the motion of our solar system. • Identify the variables that affect the strength of the gravity. • Predict how motion would change if gravity was stronger or weaker. The Student Activity includes pre- and post-labs, but these can be excluded.
Standard 6.1.2 Develop and use a model to describe the role of gravity and inertia in orbital motions of objects in our solar system.

This video segment, adapted from NOVA, traces the evolving history of theories about gravity and a force that may oppose it, along with our understanding of the impact of both of these forces on our expanding universe.
