In this fun gardening activity, learners discover their soil type. There are three basic soil types: sand, silt, and clay.

Rocks are made of minerals, and minerals often have crystal shapes. In this fun activity about geometry in nature, learners create their own crystal shapes out of paper.

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.

In this easy chemistry activity, learners submerge pennies in different liquids (water, lemon juice, vinegar, liquid hand soap, salt water, and baking soda mixed with water) to observe which best clea

This is a simple activity fully driven by imagination. Using materials from the home, toys, or items from nature, learners create their own world to play with.

This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.

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.

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

In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

In this weather activity which requires adult supervision, learners will get a chance to make a cloud right here on Earth!

In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this activity, learners working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.

Learners follow a three-step process to start their own rock collection.

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 experiment, learners work in teams to investigate how the color of a surface influences its ability to reflect light and therefore heat.

This simple, yet surprising physics demonstration challenges preconceptions about forces, and demonstrates the strength of atmospheric pressure.

Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

In this activity, learners participate in a scavenger hunt, searching for and recognizing minerals and products that contain minerals.

In this activity, learners investigate how wind can create surface currents and how waves move. Learners also discover how wind can affect oil spills.
