Discover the wind's direction using bubbles, a map and a keen eye. Learners blow bubbles and note their general direction on a map, taking readings from different points around a building.

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

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

In this collecting/comparing activity, learners work with samples of sand from different places like a lakefront, river, or ocean beach.

In this activity, learners will go outside and create a constellation.

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

In this activity, learners explore the physics of impact craters from their own backyard using mud. Learners are encouraged to match features of real impact craters to their models.

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.

This warm weather activity introduces learners to the impact trees have on blocking the sun's heat and reducing temperature on the Earth's surface.

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

Learners complete a series of hands-on and investigative activities to explore cumulus clouds.

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

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 outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.

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.

In this outdoor activity, learners will gather natural materials outside that they think a dinosaur would want to lay its eggs in.

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 use a simple 3D model to discover why the Moon has phases.

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