Learners test two jars containing soil, one covered and one open, for changes in temperature. After placing the jars in the Sun, learners discover that the covered jar cools down more slowly.

Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.

Learners observe a model of a cell and its chromosomal DNA made from a plastic egg and dental floss. Use this model to illustrate how much DNA is held in one cell.

Learners display their findings after a study of surface area and volume. They build a mobile to show a commercially available box and a constructed cubical box of the same volume.

Learners test two jars, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.

Learners set up books with rubber bands stretched between the books. When two identical books are stretched apart and released, they move back toward each other an equal distance.

Learners add drops of four liquids (water, alcohol, salt water, and detergent solution) to different surfaces and observe the liquids' behavior.

In this activity, learners develop an understanding of cylinders and volume as they compare two sizes of popcorn buckets.

In this nutrition activity, learners explore food labels and consider the nutritional value of foods. Learners also explore units of measurement commonly used on food labels.

To learn how friction affects motion, learners build a measurement tool from a rubber band and other simple materials.

In this math activity, learners use non-standard measurement (paces) to find the distance from one point to another. Learners practice estimating and measuring distances .

This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.

Straws and pipe cleaners are terrific materials for building models of pyramids and cubes.

In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.

In this activity, learners use their feet to estimate distances. Learners calculate the distance of one step in centimeters by measuring 10 steps at a time to reduce measurement error.

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

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

In this activity, learners will predict the size of a giant scale model of a comb or other rectangular object, then make one. If you tripled the size of a dollar bill, could you sit on it?

In this activity, learners investigate just how small a billionth of a meter is by attempting to cut a paper ruler down to a nanometer-sized sliver.
