Objective

By the end of this lesson, you will be able to understand the basic principles of roller coasters and how they work.

Materials and Prep

• Paper and pencil
• Internet access (optional)

No prior knowledge is required for this lesson. Just come with an open mind and enthusiasm to learn!

Activities

• Create a Roller Coaster Design: Draw your own roller coaster design on paper. Think about the different elements you want to include, such as loops, drops, and twists.
• Research Famous Roller Coasters: Use the internet (with adult supervision) to learn about famous roller coasters around the world. Find out interesting facts about their designs and record them in your notebook.
• Build a Miniature Roller Coaster: Using materials like cardboard, straws, and marbles, create a small-scale model of a roller coaster. Experiment with different track designs to see how they affect the movement of the marble.

Talking Points

• Gravity: "Gravity is a force that pulls objects towards each other. It is what makes things fall down. Roller coasters use gravity to create excitement and thrills!"
• Inertia: "Inertia is the tendency of an object to resist changes in its motion. When a roller coaster goes up a hill, it slows down because it is fighting against inertia. When it goes down a hill, it speeds up because inertia is helping it along!"
• Centripetal Force: "Centripetal force is the force that keeps an object moving in a curved path. When a roller coaster goes around a loop, centripetal force keeps it on the track and prevents it from falling off!"
• Energy: "Roller coasters need energy to move. They start with potential energy at the top of a hill, which turns into kinetic energy as they speed down. The energy is constantly changing as the coaster moves!"
• Friction: "Friction is the force that opposes motion. Roller coasters have wheels and tracks designed to minimize friction so they can move smoothly. Too much friction can slow down the coaster!"
