Year 5-8

LO:Build the Tallest Freestanding Structure

• The winning team is the one that has the tallest structure measured from base to the top of the marshmallow.
• That means the structure cannot be suspended from a higher structure, like a chair, ceiling or chandelier.
• Freestanding is defined as the structure cannot be affixed to the table in any way.

What you get..

The classes are arranged into groups of four, each group is given the following items:

• Spaghetti: 20 pieces

• Marshmallow: one

• String: 1 metre

• Masking Tape: 1m

A first, second and third prize is awarded for the tallest structure.

Further rules…

1. The Entire Marshmallow Must be on Top: The entire marshmallow needs to be on the top of the structure. Cutting, poking, or eating part of the marshmallow disqualifies the team.

2. Use as Much or as Little of the Kit: The team can use as many or as few of the 20 spaghetti sticks, as much or as little of the string or tape. The team cannot use the paper bag as part of their structure.

Further rules…

3. Break up the Spaghetti, String or Tape: Teams are free to break the spaghetti, cut up the tape and string to create new structures.
