In this activity, learners examine the different materials gardeners add to their soil, and discuss how these materials are important for plant growth.

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 weather activity (page 10 of the PDF), learners will demonstrate the changes in atmospheric pressure by constructing their own barometer.

In this activity, learners explore properties of water and watch evaporation happen by "painting" with water in the sun.

In this activity, learners observe the moon each night for a month and draw their observations in a Moon Watch Log.

In this environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.

In this activity, learners investigate and compare the rate of drying in different conditions.

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

In this activity, learners construct a simple air pressure launcher for paper rockets.

This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.

In this activity, learners create a CloudSpotter wheel and record the different types of clouds they observe twice daily over several days.

In this activity, learners use their hands as tools for indirect measurement.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

In this quick activity (page 1 of PDF under SciGirls Activity: Lift Off), learners will use the ever-popular soda geyser experiment to test the reactivity of the various sugar candies or mints.

In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a basis for thei

In this activity, learners observe tide pool animals in a touch tank to consider how they survive.

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

In this activity, learners will take a step back and learn the history of the land they live on, and the people who used to live on it.
