# Strand C: Energy and Momentum

#### Introduction to Heat Transfer

Learn about the different ways that heat is transferred.

#### Space Junk

Litter isn't just a problem on Earth. When litter ends up in space, it can cause collisions and other consequences for satellites, the International Space Station and even for people on Earth!

#### Bouncing Objects

10 images of some spherical objects such as golf balls and tennis balls that are made of different materials and used for specific purposes

#### Hydraulics 101

Hydraulics power many of the large machines you see around you.

#### How much power is generated when climbing a set of stairs?

Put on your running shoes and sharpen your pencil! Investigate the mathematical connection between work and power in this hands-on activity.

#### Generating Electricity: Hydroelectric Power

Learn how moving water can be used to generate electricity. This is called hydroelectric power generation.

In this hands on activity build a wheelbarrow from simple materials to explore just how useful simple machines can be!

#### How can you lift a marble off a table without touching it with your hands?

Is it magic? No - it’s physics! Use circular motion to overcome the force of gravity and amaze your family!

#### Can You Store Electricity for Later?

Sometimes, power plants make too much electricity. Energy storage technologies can help! They store the extra electricity and release it when demand goes up.

#### Do Woodpeckers Get Concussions?

Pecking puts a lot of force on a woodpecker’s brain. But scientists think woodpecker bodies are adapted to help keep them from being injured during pecking-related collisions.

#### Billiards and Collisions

The game of billiards shows the principles of collisions, momentum & impulse, and kinetics at work!
