• Olympic athletes are not allowed to eat dinner, so they only eat breakfast.

• The food always has lots of sugar that is used as energy.

You are building a model of the Twist-o-matic ride. You run experiments to test Rubber Band “A”, Rubber Band “B”, and Rubber Band “C”. You watch how fast the ride spins around after you twist each rubber band five times. You record your observations in this table:Why do you observe this pattern?

• Rubber band C is thicker so it stores more energy and moves faster.

• Rubber band A is thinner so it stores more energy and moves faster.

• Rubber band B is right in the middle so it works the best.
