Each group needs:

• 1 envelope containing 12 “tools,” which are items such as a sponge, rubber band, plastic sandwich bag, wooden skewer, screw, adjustable wrench, half of a paper plate, 6 inches of masking tape, pipe cleaner, shoelace, pencil and clothespin; this is an example list; feel free to substitute with whatever available “tools” you have as long as each group is given the exact same supplies.
• Pre-Assessment, one per student
• Post-Assessment, one per student
• Competition Rules, one per team (alternatively, depending on student age and reading level, you may want to review the rules verbally, as a class)
• Judging Rubric, one per team (alternatively, depending on student age and reading level, you may want to review the rules verbally, as a class)

To share with the entire class:

• table tennis ball (aka ping-pong ball)
• stopwatch
• obstacle course; set up an obstacle course that all teams use, such as one using the suggested materials below (see Figure 1), which you may want to modify, depending on available supplies and classroom space:
• 2 three-foot-long (1-meter-long) tables
• 2 wooden blocks or bricks; at least 2 x 4-inches (5 x 10-cm) in size, to create an incline on one of the tables
• ramp, such as a ~5-foot-long (1.5-meter-long) piece of cardboard or wood
• ~3-foot-long (1-meter-long) tube with a minimum 2-inch (5-cm) diameter, large enough to fit the table tennis ball
• (optional) award, treat or special privilege for the winning team(s)
