Materials World Modules

An Inquiry & Design-Based Science, Technology, Engineering, and Mathematics (STEM) Education Program

Mini Sports Materials Module

Activities
■ Measuring the Rebound of Sports Balls
■ Comparing Rolling Friction

Design Project
■ Designing a Mini-Golf Game

Through the following key select activities, students explore the materials design and function of a wide variety of balls used in athletics, as well as test and analyze their interactions with many surfaces they come in contact during play. Then students design a suitable material for use in a newly invented game.

MWM will give students an opportunity to understand the world around them in a way they have never experienced before. The modules promote an awareness of the roles science and technology play in society and guide students to take increased control of their work.

Activity 2: Measuring the Rebound of Sports Balls
Students use a drop test to compare a variety of sports balls for their ability to rebound. They draw conclusions relating rebound to the materials in each ball and to drop height.

Activity 4: Comparing Rolling Friction on Different Surfaces
Students test how different surfaces impede a ball's ability to roll. They also analyze class data to compare how far different balls rolled across the same surface.

Design Project 1: Designing a Mini-Golf Game
Drawing on what they learned about rebound, energy absorption, and rolling friction, students design a ball to be used in a new kind of mini-golf game. They will design, test, evaluate, and redesign a set of prototypes that must meet a number of specific criteria, including landing in the target area 75% of the time.

Math Teaser

The Bouncing Ball

As the Ball Bounces…

You are an observer to the following experiment (see diagram to the right). A small steel ball is dropped onto a rubber membrane covering a can. The ball bounces for one half-second, followed by a second bounce for one-quarter of a second, and a third bounce for one eighth of a second. A series of bounces will follow, each one half the duration in time of the previous bounce.

 

Question:

You are now asked to make a prediction.

  1. Will the ball continue to bounce indefinitely?
  2. Or is it possible that everything that bounces…must converge?
