Predict: Brainstorm:How are you going to tackle this challenge? What are some ideas you have?

In your STEM group, choose three objects to test on the Slip-n-Slide. Which object do you think will perform the best and why?

Slip-n-SlideSTEM CHALLENGE

Students must construct a Slip-n-Slide that effectively accelerates an object through its course. The Slip-n-Slide can have turns, hills, and decorative features in its design. The object must be going fast enough to complete the slide but not too fast where it could cause injury to the rider. Three different objects must be tested – students can decide which objects they think will accelerate at the right speed. Students have a 75 minutes to complete this challenge.
