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 dinosaur fossils and a dig site. Learners work in groups to analyze a dig site map and match bones to a skeletal drawing of Kelsey (a Triceratops).

In this outdoor biology and math activity, learners estimate the size of a population of organisms too numerous to count.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this math lesson, learners model exponential decay and exponential growth using M&M's, paper folding, and African rhino population data.

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

In this activity, young learners use different-sized paper 'caterpillars' and various household items to predict and measure their height.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

In this activity, learners explore the size and scale of dinosaurs. Learners listen to "The Littlest Dinosaurs" by Bernard Most. Then, learners estimate the size of a Triceratops and T.

In this activity about daily rhythms (on page 17 of the PDF), learners will explore circadian patterns in humans, animals and plants.

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

In this activity about bones (page 12 of PDF), learners investigate and compare the weight-bearing capacity of solid and hollow cylinders.

In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.

In this activity, learners can play two card games related to endangered species, specifically North American amphibians.

In this activity, learners will build a bee hotel for pollinators. Learners will explore building and ecology through this activity.

In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.

This activity (on page 2 of the PDF under SciGirls Activity: Doghouse Design) is a full inquiry investigation into absorption and reflection of radiant energy.

In this math lesson, learners explore probability.

In this activity, learners investigate the sense of sight and develop and conduct their own experiments.

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