In this activity, young learners go on a walk with caregivers and use their senses to observe nature with the help of scavenger hunt sheet.

In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

In this activity, learners will explore the ways natural materials can produce sounds. Appropriate for any age, learners can make individual music or create a symphony with others.

In this activity, learners will investigate the part of soil. Explore how clay, silt, and sand make up the dirt in your background. Activity includes step-by-step instructions and extension ideas.

In this activity, learners will investigate and compare the root systems of plants. Explore how weed and edible plant roots differ, and take a closer look inside with the careful use of a knife!

In this activity, learners use found natural materials to create a water haven for bees and other insects.

In this activity, learners capture and observe planaria, which are worms that eat tiny pond critters.

In this activity, learners compare plant and animal life in different habitats including a sidewalk crack and lawn. Learners sort human-made materials and natural materials found in each habitat.
