Objective

By the end of this lesson, the student will have a better understanding of roller coasters, including their history, design principles, and the forces involved in their operation.

Materials and Prep

• Internet access
• Pen and paper

Prior knowledge of basic physics concepts, such as gravity and acceleration, will be helpful.

Activities

1. Research the history of roller coasters

   Encourage the student to use the internet to research the origins of roller coasters. They can explore how roller coasters have evolved over time and any significant milestones in their development. They should take notes on the key information they discover.

2. Design a roller coaster

   Ask the student to design their own roller coaster using paper and pen. They should consider factors such as height, speed, and twists and turns. Encourage them to think about the forces involved and how they can create an exciting and safe experience for riders.

3. Create a roller coaster model

   Using materials available at home, such as cardboard, straws, or popsicle sticks, have the student build a small-scale model of their designed roller coaster. They can experiment with different track layouts and test the functionality of their design.

Talking Points

• "Roller coasters have a long and fascinating history that dates back to the 17th century."
• "The first roller coasters were inspired by Russian ice slides and were made of wood."
• "Roller coasters use gravity, inertia, and centripetal force to create thrilling experiences."
• "The design of a roller coaster involves careful calculations and considerations to ensure rider safety and enjoyment."
• "The highest roller coaster in the world is currently the Kingda Ka in New Jersey, reaching a height of 456 feet."
• "The speed of a roller coaster is determined by the initial drop and the forces of acceleration and friction."
• "The twists and turns of a roller coaster are designed to provide excitement and variations in gravitational forces."
