In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.

This marine biology activity (on pages 11-17) introduces learners to kelp (seaweed) forests that grow in the ocean and are home to many species of sea animals.

In this activity, learners explore dinosaur skeletons, anatomy, and locomotion. Learners compare and contrast dinosaur skeletons and drawings.

In this activity about dinosaurs, learners first participate in a group discussion about where and when dinosaurs lived, how big they were, and who studies them and how.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

This activity (on page 2 of the PDF under SciGirls Activity: Forecasting) is a full inquiry investigation into meteorology and forecasting.

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

In this outdoor activity, learners become beachcombers as they walk on a sandy beach in search of evidence of life.

In this activity about dinosaurs and survival, learners use scrap materials to create a miniature dinosaur habitat that includes a food source, water source, and shelter.

Just like birds, some dinosaurs had air-filled (pneumatic) bones, which made the dinosaurs' skeletons lighter.

In this activity, learners explore why animals, specifically dinosaurs, live in families.

In this investigation learners explore the differences between, and interdependence of, living and nonliving elements in a water ecosystem.

In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl

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 activity (on pages 29-35), learners examine water pollution and filtration.

In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.

In this activity related to dinosaurs, learners explore why animals live in families. Learners discuss and identify animals living in families or groups from images and photos.

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

In this activity about problem-solving, learners build a house for the Three Little Pigs using twenty straws and two index cards.
