You may wish to create challenges for accuracy, height and distance with older children. Children may document the design ideas tried throughout the process and the results through a journal.Ĭhallenge older children to discover more real-life launchers and why they are important. The process asks children to identify the problem or challenge, brainstorm possible design ideas, select a design and build it, test the design, improve the design and finally communicate their process. This activity is a great way to introduce older children to the engineering design process. If you launched something heavier than a cotton ball, would the extra weight make a difference in how far the object travelled? GOOD TO KNOW 9- 12-year-olds: What other items could you use to launch your cotton ball? What was different about the catapult designs that launched the cotton balls farther? How many times do you think scientists or engineers test their designs? Have you ever used something to launch something else or yourself?įor instance, a ball thrower, sling shot or a diving board?ĭo you think the first time always works for scientists or engineers? What are some other examples of ways that things can be launched? Observe and discuss the launching photos and/or videos. Were you able to launch your cotton ball? What did you use to launch your cotton ball? Did you make changes to the first design that launched your cotton ball? Distribute the rubber bands, plastic spoons, masking tape, craft sticks and cotton balls.


A few examples: rocket launch, catapult, baseball pitch, football toss, diving board. Have a variety of launching photos to share during the wrap-up at the end. Remember: The purpose is NOT to teach a specific topic but to help children experience the excitement of science exploration! GETTING READY
