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 capture and observe planaria, which are worms that eat tiny pond critters.

In this hands-on nature activity, learners observe the emergence of leaves and flowers. Branches from trees and bushes are collected in the early spring, brought indoors, and placed in water.

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!

This is an activity where learners will discover what types and how many insects live in their own backyard.

In this activity, young learners, (2 years and up) explore bird behavior and adaptations by providing a homemade bird feeder and observing birds.

In this activity, young learners, (2 years and up) explore animal behavior and adaptations by providing a "track trap" and observing the signs animals leave behind.

In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.

In this outdoor activity, learners investigate ant behavior by testing ant feeding reactions to different types of food.

In this outdoor art/environmental activity, learners create designs that will attract attention to animals and plants in particular habitats, and then test whether their designs attracted the "right"

In this outdoor activity, learners discover the wonders of the habitat surrounding them.

In this activity, learners will make seed orbs to grow new trees and plants. Learners will explore ecology and life cycles as well as stewardship through this activity.

Learn about friction and kinetic energy with this cool spinning toy.

In this outdoor winter activity, learners search for and create hibernation sites that will protect gelatin "animals" from freezing.

This three-part activity shows learners how to build three meteorology tools: a wind vane, a rain gauge, and a barometer.

In this activity, learners build a kite out of paper, change it, and try to make it fly even better. With their new knowledge of kite making, students can then go on to create their own kite designs.

In this activity, learners model atmospheric convection currents using food coloring, water, and clear cups. Activity includes step-by-step instructions, STEM connections, and more.

In this outdoor activity linking human health to the environment, learners use their pulse rates as a measure of the effort expended in walking on different slopes.

During this interactive "survival" game, students learn about the importance of camouflage and how it helps animals to blend into their surroundings, as either predator or prey.

In this activity, young learners (2 years and up) explore flower and plant biology and pollination by planting seed in a homemade seed starter.
