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

In this activity, learners perform an experiment that replicates the dilemma faced by birds in acquiring food from a confined area.

In this outdoor activity and game, learners explore how animals adapt for survival through coloration, markings and camouflage.

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

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

This activity guide includes instructions on how to build a "Shake Table" by mounting an eccentric mass (off center) on the shaft of a small dc motor.

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.

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 (page 1 of the PDF under SciGirls Activity: Dinosaurs), learners will model how paleontologists estimate the age of fossil discoveries by extracting “fossil” playing cards from newspa

In this activity, learners receive a labeled plastic film canister containing a material representing a pollutant (i.e. pencil shavings = a beaver's wood chips).

In this game, learners walk through an imaginary Carbon Cycle and explore the ways in which carbon is stored in reservoirs and the processes that transport the carbon atom from one location to another

In this activity, learners are invited to imagine the park of their dreams!

In this outdoor activity, learners simulate an oil spill using popcorn (both oil and popcorn float on water), and estimate the spill's impact on the environment.

In this activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho

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

In this lesson, learners will understand the concepts behind endangered and extinct animals and develop their own conservation plan to save three endangered species.

In this math lesson, learners apply the concepts of ratio and proportion to the capture-recapture statistical procedure.

This activity (on page 2 of the PDF under SciGirls Activity: Earthquakes) is a full inquiry investigation into aerial imagery.

In this activity, learners investigate the food, water, and space needs of common livestock animals.

Learners will explore the scientific mystery behind a disappearing group of trees by examining data and attempting to explain the decline.
