In this activity, learners make "totally tubular" forms of carbon. Learners use chicken wire to build macro models of carbon nanotubes.

In this activity, learners discover how frogs' bodies change while growing from a tadpole to a frog. Learners create a simple craft that gives a visual display of the metamorphosis process.

This activity demonstrates the specificity of viral vectors for target cells in gene therapy delivery methods using two approaches: 1) STYROFOAM® models demonstrate viral ligand binding to receptor pr

In this activity (on pages 36-39), learners make a model of a watershed out of paper, then run water down the mountain to simulate how rainfall and pollution affect watersheds.

This activity was designed for blind learners, but all types of learners can use it to organize an interactive model for learning the classification system (taxonomy) of living things.

Learners trace, cut out and fly a boomerang, outdoors or in a large indoor space.

In this activity, learners create three-dimensional shapes by making some origami models of simple boxes and containers.

In this environmental education demonstration (page 6 of the PDF), learners will see a tangible representation of the scarcity of soil resources on earth.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

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

Did you know that a Slinky makes a handy model of earthquake waves?

This activity was designed for blind learners, but all types of learners can explore the three states of matter by examining tactile models that illustrate the characteristics of particles in each sta

Learners cut and fold a paper helicopter from the template in this PDF. They practice twirling the helicopter and observe what happens as they modify their tries.

In this activity, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.

In this activity, learners use pop-beads to understand the characteristics and properties of polymer chains.

In this activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.

In this activity, learners eat a snack and make a model of the plumbing system of a volcano.

In this activity, learners make their own edible DNA double helix out of candy and find out about the shape of DNA.

In this activity, learners explore different types of fossils by making their out of dough and objects from around the house.

In this activity, learners play a game that models what happens as stem cells differentiate into different cell types.
