Design Challenge: Making a Catapult

Preschool Science Activities: Design Challenge: Making a Catapult

What You Need:

  • One paper cup
  • A rubber band
  • One plastic spoon
  • An action figure or similarly-sized toy
  • Pen and paper for note-taking

What You Do:

  1. First, explain the prompt of this challenge to your child. Tell them that the purpose of this activity is for them to come up with a creative way to use a cup, a rubber band, and a spoon to create a catapult for their action figure or toy.
  2. Mention that there isn’t only one way to go about this challenge: It’s open-ended, and your child should know that they can come up with several different ideas.
  3. Once your child has a clear understanding of the prompt, it’s time for them to BrainstormDifferent ways they can use their materials. Feel free to show your child the materials you’re providing, but don’t let them start building quite yet.
  4. Ask your child to write or draw all their ideas on a piece of paper so that they can refer back to them. Alternatively, you can ask your child to explain their ideas to you while you write and draw them on a piece of paper.
  5. After your child has brainstormed for a few minutes or can no longer come up with any ideas, ask them to choose the idea they think will work best. This is an important step of the design thinking process because it teaches your child to prioritize the functionality of their design over their personal preferences. Also, this will help prevent your child from getting emotionally attached to a single design.
  6. Now that your child has decided which design they think will work best, allow them to start Building! In order to develop resilience, it’s important that your child learns to work through challenges independently. However, depending on the capabilities (and age) of your child, you may need to assist them as they put their prototype (design) together.
    1. Generally, we recommend that you intervene only if you have a safety concern or if you feel that your child absolutely can’t make any progress without your assistance.
  7. After your child has finished building their prototype, it’s time to TestIt out! Allow them to try launching their action figure and observe the process.
    1. If the catapult successfully launches the toy, congratulate your child on their success.
    2. If the prototype doesn’t work, make sure your child doesn’t feel discouraged. It’s important to encourage your child to identify why their design didn’t work, and help them go back to the beginning of the design thinking process to create a better one. Before your child starts over, you may want to ask them the following questions so that they can think about what they should change in their next design: “What worked with your design? What didn’t work with your design? Which part of your design do you think you should change next time?”
  8. Continue repeating this process until your child has created a catapult they are proud of!
  9. In order to have your child reflect on the design thinking process, ask them some of the following questions:
    1. What was the best part about your final design?
    2. What could you have improved in your final design?
    3. What was the most challenging part of this activity?
    4. What did you learn?
