In this physical science engineering activity, students will have fun designing, drawing, and building K’nex vehicles to meet specific challenges. They will discover the different forces at play as ...

Students will apply their knowledge of physical science concepts to create a lunar lander game using Scratch. They will use Vernier force and acceleration sensors to understand forces and integrate ...

Tugging a small toy with your dog can be a lot of fun—but it’s also a great way to experiment with forces acting on an object. Forces are what scientists call the pushing and pulling on objects. In ...

Why do things fall? It’s about force and motion. Find out more in this Science Trek short. A force is basically a push or a pull. Forces like gravity, inertia, and momentum affect everything. On this ...

Magnetism is a natural force, one that works at a distance. Magnets get their force from magnetic fields created by the atoms within the metal. Magnets are useful for things like turbines we use to ...

All of the objects in our solar system are acted upon by forces. Forces are pushes or pulls. Every force has both a strength and a direction. Applying a force on something–like pushing a toy car–can ...
