In this activity, learners create a soil and water model of a single-cell life environment and study living microorganisms.

In this activity, learners will put a set of containers in order by capacity. Would the tallest container hold more or less water than the wide, short one?

In this activity, learners examine photo images of Earth taken from space, and attempt to identify and explain some of our planet's geological features.

In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).

In this activity, learners use sand and ice cubes to create a model of permafrost and the effects of the ice melting through the surface.

In this group activity, learners consider environmental conditions—temperature, presence of water, atmosphere, sunlight, and chemical composition—on planets and moons in our solar system to determine

In this playful activity, learners explore the structure of the cell—the basic unit of every living organism—by creating a model of cell structures using soap bubbles, and by examining a slice of onio

An outdoor scavenger hunt helps learners consider the theme of "What Is Life?" Learners explore what living organisms are, including how organisms meet basic needs of food, shelter and water to surviv
