In this math lesson, learners predict, interpret, and sketch graphs of functions related to the shapes of bottles. A measure of water is poured into a container.

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

In this exercise (Activity #2 on page), learners test their distance vision to evaluate their overall eyesight.

This activity introduces the idea that computer scientists measure information by how "surprising" a message is.

In this activity, learners explore how engineers use scales and measures when designing a manufacturing process to ensure that final products are uniform in weight or count.

In this math activity, learners pretend there is a special store that lets you pay for toys by their weight in pennies.

In this math lesson (page 2 of the PDF), learners use bottles of various shapes to explore the abstract concept of rate of change.

In this math lesson, learners measure, predict and determine the frequency of an event as it relates to how close Whirlybirds land to a target.

In this activity (page 2 of PDF under GPS: Glaciers Activity), learners will measure the rate at which water streams out of a leaky cup.

This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.

The demonstration/experiment provides quick proof that air has mass.

In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

Historically, sea floor mapping (bathymetry) was done by soundings.

In this activity, learners will measure their lung capacity by making their own spirometer. Learners will then explore factors that affect the amount of air the lungs can hold.

In this activity, learners explore how spring scales work and how they are used for non-exact weight measurement.

In this "Sid the Science Kid" activity from Episode 107: My Shrinking Shoes, learners observe how plants change as they grow.

In this activity about the brain and sleep (on page 138 of the PDF), learners measure their resting breathing rates. Learners will discover that breathing frequencies vary amongst individuals.

In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

In this activity, learners count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.

In this environmental health activity, learners investigate their own vital lung capacities.
