In this math activity, learners create their own units of measurement by making noodle rulers. Learners practice estimating and measuring objects using the noodle rulers .

In this activity, learners compare the ancient Egyptian system of measurement, which was based on body lengths, to the customary and metric systems used today.

In this activity learners will measure and manipulate flubber using different tools. Learners will explore volume and make observations about texture and shapes.

This activity (located on page 2 of PDF) introduces learners to the real size of animals using nonstandard measurement.

In this Cyberchase activity, learners use math to explore how parts of the body are proportional.

In this math activity, learners jump and measure how far they can jump on different surfaces using different jumping techniques.

In this activity, learners investigate whether more people are squares or rectangles. People with similarly sized heights and arm spans are classified as squares.

In this activity, learners explore and experiment how we can use our bodies everyday to get from one place to another.

In this coin math activity, learners sort and stack 100 (one hundred) pennies into piles of 5 pennies each, 10 pennies each, and 20 pennies each.

Create a “Find Someone” list, with about 10 items, each containing a shape, number, or measurement. Can you find someone in the group with hair about 4 inches long? Someone wearing parallel lines?

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

In this activity, learners will decide together on a question about how far, long or high the group could reach together.

In this activity, learners create a map of a hidden surface using a "sounding stick" -- a technique similar to how underwater maps were once made.

In this activity, learners will build thier own balance scale. Learners will explore weight and comparison through this activity.

In this activity, learners will estimate the sizes of balls to learn how to estimate the size of hail. Learners will compare their estimates to the estimates of their peers and the real measurements.

In this activity, learners mimic remote sensing. Learners use a stick to measure the distance to a "planet surface" they cannot see, and create their own map of the landscape.

Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.

In this physics activity (page 12 of the PDF), learners explore potential and kinetic energy by rolling different sized marbles down an inclined plane.

In this health activity, learners create a device so that they not only feel their heartbeat, but also see it, using a straw and some clay.

In this physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.
