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

In this activity, learners cut out a fish and then "paint" it using universal indicator and acids and bases.

In this activity, learners will explore reptile biology by taking temperature readings in various places and comparing them.

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

The goal of this activity is to design, build and test a house or toy for an animal.

In this group activity, learners act out key stages of the "ocean carbon cycle" (also known as the "carbonate buffer system") through motions, rearranging blocks and team tasks.

In this activity, young learners, (2 years and up) explore bird behavior and adaptations by providing a homemade bird feeder and observing birds.

In this activity, young learners, (2 years and up) explore animal behavior and adaptations by providing a "track trap" and observing the signs animals leave behind.

In this activity, young learners (2 years and up) explore flower and plant biology and pollination by planting seed in a homemade seed starter.

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.

In this wintertime outdoor activity, learners role play wolves tracking their prey by following scented trails.
