General Guide to Adaptations

Description

A catapult is a simple machine that is used to make things fly through the air.

Present a basic catapult and say something like “This is a catapult. I want to make this pom-pom fly through the air. Can you use these items to help me make the catapult move the pom-pom further?” 

Take note of how far items go and challenge children to evaluate and adjust the catapult.

Environment

Lead the activity outside so items can fly farther.

Materials

  • Ensure the catapult and load are large enough for children to easily grasp and manipulate.
  • Include visuals that represent different materials and steps involved in making/using the catapults.
  • Consider using materials that are highly contrasting in color to support visual discrimination.
  • Use materials that make a sound when they “land” to increase child engagement.

Instruction

  • Provide choices for children when making improvements.
  • Break down the activity into smaller step.
