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

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

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 online game, learners must purchase power plants for their city.

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, 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 activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

In this activity, learners learn about the adaptations that flowers have developed which support pollination. Learners also list their personal preferences (i.e.

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

In this activity (on pages 18-28), learners explore how the shape of seeds affects how they are dispersed by wind, birds, ocean currents and other means.

In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause

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

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

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

Water treatment on a large scale enables the supply of clean drinking water to communities.

In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this online simulation, learners can see adaptation and camouflage in action.

In this environmental science activity (page 4 of the PDF), learners use vinegar and chalk to observe the effect of acid rain on various building materials and plant life.
