In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

In this activity, learners help identify native and non-native plant species, learn about invasive species, and determine how native plants provide a healthier habitat.

In this activity, learners create a garden in a disposable glove. They learn about the conditions necessary to make the seeds sprout and actively participate in caring for their plants.

In this outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve water.

In this activity, learners conduct an experiment to investigate the effect of elevated levels on CO2 on plant growth.

As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.

In this outdoor activity, learners make models of homes that might protect small animals from the elements, then search living plants for real structures made by small animals.

In this outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.

This outdoor activity (on page 2 of the PDF under SciGirls Activity: Sand Dunes) is a full inquiry investigation into how the amount of moisture in a sand dune relates to the number of plants growing

In this activity (Page 22 of PDF), learners investigate the evolution of wheat by washing different types of dough with water and comparing the results.

In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.

In this activity (Page 25 of PDF), learners investigate the evolution of wheat by creating dough from different flours, observing the samples of dough as they rise, and then baking the dough.

In this outdoor activity, learners find, count and compare as many different kinds of animals as they can find in two different areas: a managed lawn and a weedy area.

In this outdoor activity that can be combined with a hike, learners try to match a "mystery community" by shaking animals out of different trees and shrubs.

In this outdoor, ocean-side activity, learners investigate the distribution of organisms in the upper region of the intertidal zone.

In this indepth hands-on activity, learners build a structure that allows them to observe the growth of roots and the correlation between root growth and stem extension.

In this outdoor activity/field trip, learners locate and study plants and animals in several freshwater pond habitats.

In this activity, learners build one or more edible coral polyps and place them together to form a colony.

In this activity, learners create a freshwater ecosystem in a large plastic bottle. Learners cut and prepare bottles, then fill with water, aquatic plants, snails and fish.

In this outdoor activity, learners investigate the relationship between the slope of a trail and soil erosion.
