Learners use a variety of beans to represent a variety of species, and scatter these beans over a large piece of paper representing the environment.

In this hands-on activity, learners make New Year's Eve party hats out of wrapping paper. Learners use symmetry and measurement to cut out shapes they need to assemble the hats.

In this math activity related to volume, learners use problem solving skills to calculate and build a model house for Minus the dog.

In this activity, learners use a straight line to learn about circles. Learners measure and record the diameter and circumference of different sized cylindrical objects on a chart.

In this online activity, learners adjust mountain snowfall and temperature to see how glaciers grow and shrink. They will use scientific tools to measure thickness, velocity and glacial budget.

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.

In this math lesson, learners estimate distances between landmarks and use a map and scales to determine the actual distances.

In this activity, learners discover the importance of maps and scale as they work together to create a map of the classroom.

Learners will explore the concept of angular distance, and investigate why the moon appears to be the same size as the sun during a solar eclipse, despite the sun being much larger.

In this math activity, learners estimate how many pennies are in a jar by predicting and counting handfuls of pennies.

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 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.

Learners build a simple one-cell battery and use an ammeter to measure the flow of current.

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.

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