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.

In this activity, learners investigate how different materials repel or absorb water. Learners use spray bottles to explore how everyday items like sponges, cardboard, feathers, etc.

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 activity, learners will explore reptile biology by taking temperature readings in various places and comparing them.

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

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

In this activity, learners are challenged to build a bird feeder using recycled materials from home and are encouraged to problem solve during the extensions.

In this activity (located on page 4 of PDF), learners gain insight into the actual size of dinosaurs and practice making estimations and measurements.

In this weather forecasting activity, learners use common materials to construct a rain gauge and measure daily, monthly, and yearly rainfall.

This is an activity about discovering the colors and beauty of nature. Learners will spend time outdoors, matching paint chip samples, colored paper, or colors of clothing to those found in nature.

In this activity, learners investigate the concepts of relative size and distance by creating a basic model of the solar system.

In this activity, learners build a bird feeder or feeders to attract birds for observation.

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 activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

In this activity, learners make a photographic image—without a camera!

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

In this craft activity, learners create a string of cut-out moons and stars.
