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 outdoor activity, learners design devices that will catch prey or gather plants.

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 explore how engineers work to solve the challenges of a society, such as efficient planting and harvesting.

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.

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

In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.

In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

In this outdoor activity, learners go "can fishing" and discover the kinds of aquatic organisms that live in and on submerged cans.

In this activity (on pages 18-29) learners explore the impact of the March 24, 1989 oil spill in Alaska caused by the Exxon Valdez tanker.
