In this outdoor activity, learners discover how the environment around a building affects the growth of plants.

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 make a model of a power plant that uses steam. Learners use simple materials like foil, a tin can, and a pot of water to model a geothermal power plant.

In this activity (on pages 20-23 of PDF), learners build a model of a power plant using simple materials.

In this activity, learners will dissect a pumpkin or winter squash to learn the parts of the plant. This activity gets your learner hands on with every part of the plant and will be messy.

In this activity, learners will explore vegetative propagation while preparing food scraps to grow into plants.

This modeling activity allows learners to discover for themselves what Mendel uncovered in his famous pea experiments.

In this activity, learners will examine a variety of seeds, describe them, and determine how they are dispersed.

In this activity, young learners will make their own flower seed nursery in an egg carton.

This lesson introduces learners to the world of nematodes (roundworms).

In this laboratory exercise, learners will discover how many different plant hosts they can find that are infected by the same genus of a powdery mildew fungus, or how many different genera of powdery

Learners create a model of a wetland to observe how it absorbs and filters water from the environment.

By participating in a seed scavenger hunt, learners examine many adaptations of seeds, including how many seeds a plant makes, how those seeds travel to new locations, and what protects them from pred

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

In this activity, learners use food scraps from the kitchen to grow new vegetables.

Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.

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

In this activity, learners survey living organisms near where they live or go to school, and create a local field guide.
