Immerse yourself in a world of large and small, shadows and shapes, motion and sound in the Math Moves exhibition. Ready. Set. Grab a friend, get moving and watch as you and your friend’s rates of motion are tracked on a screen. Do you hear that? Listen, watch and feel what happens when you change the pitch and frequency of sounds. 

Ever use your body as a unit of measurement? Here’s your chance – simply hop in a huge chair then sit in the tiny one to compare your size. Ever wonder how your shadow changes sizes? Here you can grow, shrink, match and measure while discovering connections between shapes, shadows and sizes.

	Balance and Imbalance challenges visitors to hang weights on three types of balances to discover proportions of distance and weights.
	Comparing Frequencies creates rhythmic percussive sounds using one or more small wheels driven by a large wheel. Visitors can experiment with several wheels to compare frequencies of the clicks.
	Shadow Fractions allows visitors to experiment with the placement of objects to make shadow stories or scenes. By moving these objects - growing or reducing the size of its shadow - visitors are directly experiencing concepts of ratio and proportion.
	Comparing Forms invites visitors to sit in three chairs that are identical in every aspect except proportional scale. A truly physical experience, visitors can use their body and other measuring tools to investigate how the chairs differ in size, and begin to understand the geometric concept of similarity and proportional relationships between different-sized objects.
	Scaling Shapes lets visitors enlarge simple objects by doubling all three dimensions. By introducing concepts of volume and three-dimensionality, this challenging exhibit is a good companion piece to the Comparing Forms exhibit and extends the study of scaling, similarity, and proportionality.
	Sensing Ratios is designed to explore ratios by hearing sounds as well as by drawing. Visitors move knobs and compare the tones generated as they draw lines on the screen.
	Partner Motion provides visitors with an opportunity to see how their rate of motion affects a graph on a screen. Walking back and forth, slowly and quickly, experimenters create graphs of their motions along with the motion of their partner.
	Half, Whole, Double invites visitors to use their whole body to change and compare the size of their shadow on a huge grid — a life-size version of the Shadow Fractions table. Located on the 2nd floor.
	Movie Ratios inspires visitors to make their own stop-motion animation movie and experiment with changing its speed and length. Visitors can also submit their videos online and view them from home later. Located on the 2nd floor.
