In this yummy biology activity (page 3 of the PDF), learners participate in a demonstration of natural selection.

In this activity (6th on the page), learners investigate how photoreceptors in the eye (rods and cones) "adapt" to low light conditions.

In this activity, learners observe live fish in tanks to consider how their body structures are related to their behaviors and habitats.

In this online activity, learners find out whether they are smart enough to survive as a plant.

In this activity, learners use measurement concepts to make models of what their body parts might look like if they were a snake or a chameleon.

In this activity (p.7-8 of PDF), learners examine fossil formation.

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 activity, learners play bingo to learn about the diversity of birds. This game includes a warm-up lesson and "Full Flight" version.

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 activity, learners will discover what it takes to be a frog. By dressing up like one, learners can visualize how each part of the frog plays an important role in surviving its habitat.

This is an activity about dinosaurs, fossils, and the work of paleontologists. Learners use hand tools (paint brushes, scoops, and sifters) to unearth fossil specimens in tubs of birdseed.

In this online interactive, learners use fossils to infer temperatures 55 million years ago, at the sites where the fossils were found.

In this art-related activity, learners make a coin rubbing—a process similar to what archeologists may do with ancient artifacts. This activity can be used in connection with a history or art lesson.

This activity is on page 8 of the pdf, part of the Sea Life Discovery Box. This is an activity exploring the characteristics of fish.

In this activity, learners investigate different types of bird beaks using household items which mimic different beak examples.

In this activity, learners will explore how animal in cold areas stay warm.

In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur

In this activity, learners will explore how different bird beaks work and discover what birds can eat based on their beak shape.

In this interactive activity, learners analyze seashells to explore phylogeny and evolution. Learners identify similar and dissimilar seashells to create a phylogenetic tree.
