Learners observe a model of a cell and its chromosomal DNA made from a plastic egg and dental floss. Use this model to illustrate how much DNA is held in one cell.

Using pipe cleaners, straws, and beads, learners explore the building blocks of life by creating their own model of DNA.

This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.

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

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 fun group activity involving music and movement, learners are introduced to the idea that many insects walk by using their legs to create "alternating triangles." Learners sing the "Ants Go Ma

In this activity, learners explore how genetic switches function and the role of genetic switches in the process of evolution.

In this activity, learners create volcanoes like those they have examined on Earth and Mars through images taken by spacecraft.

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

In this indoor and outdoor activity, learners discover that insects grow and develop as do all living things, going through a process known as complete metamorphosis.

This neuroscience activity introduces learners to how messages are sent and received by neurons. Learners use modeling clay and pipe cleaners to build model neurons.

In this activity, learners create their own archaeological profiles.

In this activity, learners imitate the way vocal cords work by building a model from a plastic cup, rubber band, and a straw.

In this activity, learners explore dinosaurs and fossils by creating a diorama.

In this multi-step experiment (page 4 of pdf), learners study tide pools, and then drop a "wave" (a 4-pound bag of beans or birdseed) on a shell to mimic the force of crashing surf on tide pool animal

In this activity (page 4 of the pdf), learners build a model of a tide pool, using chicken wire, paper mache, and other craft materials.

In this activity about human anatomy (page 16 of PDF), learners construct a model arm and discover how muscles and bones work together to achieve efficient movement.

In this activity, learners identify the DNA base bars guanine, cytosine, thymine and adenine. Learners create a DNA model using colored paper clips to resemble these base pairs.

In this activity, learners cut, fold, and paste paper representing biomolecules to create a three-dimensional cell membrane with embedded proteins.

In this activity, learners explore dinosaur skeletons and anatomy. Learners make observations about a T. rex skeleton diagram and then measure the skeleton length and width.
