In this “Move It” challenge, students will work in teams to build a rubber band powered crawler transporter that can carry a payload at least one meter. This engineering design challenge comes from NASA’s Build, Launch, Recover Education Guide and is one of our most exigent challenges to date. We want your students to be successful, which is why we share tips to help you guide your students should their rubber band powered crawlers not work as expected.

RECOMMENDED MATERIALS
A Cardboard box (e.g., shoebox or cereal box)
Rubber bands, #33 (3 1/2 x 1/8 in.)
Wooden dowels or skewers
Adhesive
Small round objects for wheels (e.g., bottle caps) in sets of 4
A Ruler
A Metric tape measure or meterstick
Safety eyewear
Various payloads of up to 1 kg (e.g., book, plastic bottle)
Scissors
Tape (optional)
Straws (optional)

SAFETY INFORMATION
Practice safe cutting and handling techniques when building crawlers.
Eliminate sharp or pointed surfaces that could present a hazard.
Wear eye protection when handling and releasing the crawlers during the distance test.
Clear the test zone of students and items that may be in the path of moving crawlers.
