In this activity, learners make pykrete by freezing a mixture of water and a material like cotton wool, grass, hair, shredded paper, wood chips, or sawdust.

In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

Millions of organisms can live in and around a body of water.

In this activity, learners will create a soil profile in a bottle. They will learn about the organic and inorganic matter found in soil and observe as it separates into layers in the bottle.

In this activity, learners investigate soil conditions by creating a soil map. Learners record soil characteristics and compare the conditions of soil in different grid sections.

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 hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook

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 work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

This activity gets learners looking at 6-sided shapes in nature, including the cells of a beehive, as well as other shapes.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.

This activity introduces learners to Native Americans as people who depended upon nature in the past and continue to emphasize the importance of nature in the present.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

Build a fruit fly trap out of a 2-liter plastic bottle and some rotten fruit! Fruit flies are easy to catch in warm weather. Once you catch some, you will be able to see their life cycle up-close.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.
