"Science in Focus: Force and Motion"

Explore science concepts in force and motion and come away with a deeper understanding that will help you engage your students in their own explorations. With science and education experts as your guides, learn more about gravity, friction, air resistance, magnetism, and tension through activities, discussions, and demonstrations. Extensive footage shot in real classrooms shows students learning and building on ideas as they explore the relationships among motion, force, size, mass, and speed. As you watch the students develop understanding through activities that connect science concepts to real-world phenomena, you will be asked to think about your own ideas on force and motion and compare them to what you observe.

Workshop 6: Force Against Force
From learner.org, produced by Harvard Smithsonian Center for Astrophysics
Magnets stick to other magnets and to metal objects made of iron or steel. How much force is required to break the attraction between two magnets? In this workshop, fourth-grade students explore ways to balance the force of magnetism against the forc... [more]

Workshop 7: The Lure of Magnetism
From learner.org, produced by Harvard Smithsonian Center for Astrophysics
What is the difference between a permanent magnet and an electromagnet? In this workshop, fourth-grade students build an electromagnet by winding a wire around a rivet and attaching the ends to battery terminals. The students first predict how many w... [more]

Workshop 2: Drag Races
From learner.org, produced by Harvard Smithsonian Center for Astrophysics
Forces can help put objects into motion and can also bring moving objects to a stop. In this workshop, fifth-grade students explore the physics of motion using plastic cars with strings and washers attached to provide a pulling force. The students te... [more]

Workshop 1: Making an Impact
From learner.org, produced by Harvard Smithsonian Center for Astrophysics
What would happen if an asteroid were to hit the surface of the earth? How large a crater would the impact create? In this workshop, the ideas of force and motion are introduced, as seventh-grade students drop balls to simulate asteroid impacts. By v... [more]

Workshop 3: When Rubber Meets the Road
From learner.org, produced by Harvard Smithsonian Center for Astrophysics
A rubber band twisted around the axle of a plastic car provides the force that moves the car forward. In this workshop, fifth-grade students continue their exploration of force and motion by recording and comparing the distance a vehicle travels unde... [more]

Workshop 8: Bend and Stretch
From learner.org, produced by Harvard Smithsonian Center for Astrophysics
We all expect a spring to stretch or compress when a force is applied, but forces can even deform solid objects like the floor or the top of a table. In this workshop, students in a high school classroom explore ideas about tension and normal force. ... [more]

Workshop 4: On a Roll
From learner.org, produced by Harvard Smithsonian Center for Astrophysics
The force of gravity makes a ball roll when it is placed on an incline. In this workshop, first-grade students roll balls of different sizes, masses, and materials down ramps of varying heights, comparing their speeds. The students then experiment by... [more]
