In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.

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

In this outdoor activity, learners discover that plants aren't just shoots (stem, branches, leaves, and flowers) growing above ground, but contain plenty of roots growing underground—more than half th

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

In this outdoor activity/field trip, learners explore the concept of population density.

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

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.

In this outdoor, windy day activity, learners "fly" and race leaves along a line to discover which types of leaves catch the most wind. Which leaves are the best fliers? Why?

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

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

In this creative outdoor activity, learners invent populations of make-believe organisms and then investigate real populations living in the activity site.

In this biology/ecology activity, learners construct a terrarium out of a tennis ball container. This terrarium is unique because it never has to be watered.

In this outdoor activity and bingo-like game, learners explore why and how seeds spread far from the plants that produce them.

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

In this outdoor activity, learners become beachcombers as they walk on a sandy beach in search of evidence of life.

In this activity (on pages 10-17), learners discover how scientists study biodiversity and the health of the environment based on inspection of small areas—a process known as sampling.

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

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.
