What you’ll do.

A traveling exhibit about length, time, volume and weight: a height wall, a treadmill odometer, calipers and gauges, a giant tape measure, a foot ruler and more. Created by Children's Museum of Pittsburgh.

Open May 16, 2026 to September 13, 2026.

Height wall: measure yourself in apples or pennies
Treadmill odometer adding to a running visitor total
Ball gauges: calipers, height gauges and go/no-go gauges
Giant tape measure and the foot ruler

How many chickens do you weigh? How tall are you in apples or inches or pennies? Can you use your foot as a ruler? The answers to these and other questions can be explored at Measurement Rules, an interactive exhibit at Creative Discovery Museum from May 16 to September 13, 2026.

You can explore concepts of length, time, volume and weight in a variety of ways.

Length

Height Wall. How tall are you in apples or pennies?
Treadmill Odometer. Get walking and add to the total yards visitors have walked on our treadmill in the exhibit.
Ball Gauges. Tinker with instruments such as calipers, height gauges and go/no-go gauges. Explore all of the possible ways to measure an ordinary wooden ball. Toss the balls down the chutes to test your findings.
Giant Tape Measure. Extend a giant tape measure to measure the equally giant fish on our wall mural.
Foot Ruler. Fit your foot into the gauge to make your foot a unit of measurement, then measure yourself in your "feet" and other people's "feet."

Time

Five Mississippi. How good is your internal clock? Count to five Mississippi and see how close you come to five actual seconds.
Ball Stopwatch. Build your own ball ramp and make it faster or slower with modifications.

Volume

See Your Volume. Step before the screen and see yourself built from cubic-inch blocks.
Bead Table. Little ones can explore volume at an open-ended bead play table.

Weight

Chicken Scale. Find out how many chickens you weigh.
Balance Scale. Finesse the right balance between objects and standard weights on a large balance scale.
