fun
You don't need snow
to have fun sledding!
For this challenge, teams must design a sled.
-
The objectives (criteria) are to make the sled as fast as possible, and for the sled to safely carry its rider (a beanbag animal) to the base of the hill.
-
The constraints are that students must only use the materials provided, must complete a prototype in 20 minutes, and must NOT tape the rider to the sled.
The materials for the sled include:
-
cardboard from a cereal box,
-
a 6-8" wide piece of waxed paper,
-
a 6-8" wide piece of aluminum foil,
-
4 wide craft sticks,
-
6 small craft sticks, and
-
approximately 18" of masking tape.
​
Any large inclined plane may serve as a hill. I fashioned our "hill" by taping two parallel yard sticks to the back of a sheet of cardboard. The top edge of the hill was propped against a chart stand and its bottom edge sat on the carpet.
