In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this activity, learners explore the behavior of cold-blooded animals. Learners discover what happens when they change a fly's temperature.

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

In this outdoor activity, learners discover the wonders of the habitat surrounding them.

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

In this outdoor activity, learners investigate ant behavior by testing ant feeding reactions to different types of food.

Learners use a variety of beans to represent a variety of species, and scatter these beans over a large piece of paper representing the environment.

This activity encourages learners to focus on the natural environment of the Eastern Woodlands before the arrival of European settlers.

An outdoor scavenger hunt helps learners consider the theme of "What Is Life?" Learners explore what living organisms are, including how organisms meet basic needs of food, shelter and water to surviv

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

Have you noticed the plastic rings that are used to hold six-packs of soda? Those rings are great for carrying cans, but they're real trouble when they become trash that animals can get tangled in.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this activity, two groups of learners create two separate landform models out of clay (mountains and valleys).

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

In this activity, learners construct a traditional handicraft toy that illustrates a motion commonly associated with violins and earthquakes.

In this activity (Lesson 1), learners work in groups to create tide simulations.

In this laboratory exercise, learners will discover how many different plant hosts they can find that are infected by the same genus of a powdery mildew fungus, or how many different genera of powdery

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 outdoor activity/field trip, learners explore the concept of population density.

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.
