Cricket Wicket Knockdown Challenge for Grades 3-5
- Design and build a ball launching machine based on specific criteria
- Iteratively test and modify the machine to improve its performance
Teach your students about the engineering design process with this fun lesson plan. They will design and build a ball-launching machine to knock down a target. Optionally, they can enter their designs in the 2020 Fluor Engineering Challenge for a chance to win a cash prize for your school! Teachers, note that middle school and high school versions of this lesson plan are also available, as is a Spanish language version of the basic challenge.
NGSS AlignmentThis lesson helps students prepare for these Next Generation Science Standards Performance Expectations:
If you want to enter your device in the 2020 Fluor Engineering Challenge, you can only use the materials listed below. Each item has a maximum allowable quantity and a point cost (each) that will be deducted from your score. Note that you can cut the materials, but costs are not prorated; e.g., if you cut a piece of paper in half and only use half of it, it still costs 10 points.
