EcoTarium New Exhibit: Measurement Rules

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 The EcoTarium Museum of Science and Nature. On Saturday, February 3rd, the EcoTarium celebrated the launch of this highly anticipated traveling exhibition, which will be on display from now through mid-May 2024.

About Measurement Rules

It might be common to measure using standard tools such as measuring tapes and vessels – but the Measurement Rules exhibit explores some creative, nonstandard ones such as balancing scales, odometers, calipers, 3-D imaging and counting “Mississippis.”

“We are excited to offer this new interactive traveling exhibit on the concept of measurement which is fundamental to every field of science,” said Noreen Johnson Smith, President and CEO of the EcoTarium. “This exhibit makes it fun to explore a variety of measurement techniques in a silly and engaging way. For the record, I weigh 33 chickens.”

Measurement Rules was created by Children’s Museum of Pittsburgh. “We’ve designed this exhibit to enable kids to work together and become more confident in the language of measurement,” explains Anne Fullenkamp, Children’s Museum of Pittsburgh’s Director of Design.

This exhibit enables visitors to explore concepts of length, time, volume and weight in a variety of ways:


Height Wall – How tall are you in apples or pennies?
Treadmill Odometer – Get walking and add to the total yards we’ll calculate visitors 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.”


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.


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.


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.
