In this activity, learners create virus models, including nucleic acid and proteins, using simple materials. This resource includes information about virus structure and gene therapy.

This activity (on page 3 of the PDF under GPS: Cactus Activity) is a full inquiry investigation into how some desert birds keep their cool.

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 take on the role of various parts of the cell in order to model the process of protein synthesis.

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

In this ecology activity, learners make a model water-based ecosystem called a terraqua column. The column (in a large soda bottle) includes pond water, duckweed, sand or gravel, and small snails.

Learners will construct a model of a heart valve using a film canister, a piece of masking tape, and a piece of paper.

In this two-part activity about the connection between the lupine plant and butterflies, learners first read "Miss Rumphius," a storybook about lupine by Barbara Cooney.

Learners will explore the chemistry of mucous and its importance to our health by following a process to make their own replica "snot." The activity includes a time and age recommendation, a materials

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.

In this activity, learners make a 3-D model of DNA using paper and toothpicks. While constructing this model, learners will explore the composition and structure of DNA.

In this activity, learners construct a model of DNA to better understand the structure of DNA and protein synthesis.

In this 6-7 day investigation, learners begin with an introduction to seamounts that are present in the Gulf of Alaska.

In this activity, learners create an origami model of DNA, demonstrating its double helix structure.

In this inquiry-based activity, learners investigate the basic forces of flight as they construct their own paper glider that represents a rainforest creature from Borneo (large, tropical island in So

In this activity, learners create a three-dimensional sculpture while examining the characteristics of fish.

In this activity, learners solidify their conceptualization of cells by building a model of a cell in a ziplock bag.

In this activity (located on page 5 of PDF), learners work in groups to create dig sites for display.

In this activity, learners build one or more edible coral polyps and place them together to form a colony.

In this activity (on page 6 of the PDF), learners plot the path of the sun's apparent movement across the sky on two days, with the second day occurring two or three months after the first.
