Each group needs:

• Note: for mint-mobile construction supplies, the exact amounts required depend on the team's vehicle design; rough estimates are provided
• plastic drinking straws (estimated 4-6; make sure the straw diameter is smaller than the mint candy's hole diameter)
• Popsicle sticks (estimated 2-4)
• lifesaver-shaped candies, such as Lifesaver® mints (estimated 3-6)
• index cards (estimated 1-2; or thin cardboard or poster board scraps)
• tape, any type; duct or masking preferred
• scissors
• paper and pencil
• Design Worksheet, one per student

For the entire class to share:

• ramp, for testing, made from sturdy poster board, rigid cardboard or thin wood
• Gather two pieces of poster board, rigid cardboard, or thin wood of different lengths, for testing the independent variable of ramp length
• meter stick, for measuring the distance traveled
• pennies, for added mass during testing (estimated 10-30 pennies; depending on robustness of mint-mobiles, individually tape pennies on vehicles, or tape a little baggie of pennies to the design
• tape, for securing the ramp, meter stick and pennies
• (optional) hot glue gun and glue sticks
