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 design challenge activity, learners build a machine out of cardboard that runs smoothly and dependably. Learners must be precise to make sure their component works properly.

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.

In this activity, learners investigate the formation of craters. Learners will examine how the size, angle and speed of a meteorite's impact affects the properties of craters.

In this activity about ramps, learners explore and measure the rate at which spherical objects roll down a ramp.

In this activity learners observe mold growth on different types of bread by measuring and recording the growth rate.

In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

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 activity, learners explore the concepts of structural engineering and how to measure the critical load, or the maximum weight a structure can bear.

In this activity (26th on the page), learners construct an easy-to-build device and test motor learning.

In this activity, learners build a simple pinhole viewer. They use this apparatus to project images from a variety of light sources, including a candle, the Sun, and the Moon.

In this activity, learners compare ways to measure their heart rates. Learners build their own stethoscopes and learn how exercise affects heart rate.

In this activity, learners build mini-basketball courts using cardboard and measuring spoons. Use this activity to introduce learners to catapults, forces, and levers.

In this activity, learners create a garden in a disposable glove. They learn about the conditions necessary to make the seeds sprout and actively participate in caring for their plants.

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.

In this quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this activity, learners make a scale model of an atom to see how big or how small an atom is compared to its nucleus. Learners will realize that most of matter is just empty space!

In this outdoor activity linking human health to the environment, learners use their pulse rates as a measure of the effort expended in walking on different slopes.

In this activity, learners interpret three trackways and use measurements and a formula to infer the relative speed of dinosaurs.
