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

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

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

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

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

In this activity (pages 7-16), learners model various crystal structures with LEGOs. This activity also contains additional links that explain how to create other crystal structures.

Build a catapult that transforms the potential energy of a twisted rubber band into kinetic energy. Experiment with design variations so that you can hit a target with a projectile.

In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.

In this activity, learners create a model of a neuron by using colored clay or play dough. Learners use diagrams to build the model and then label the parts on a piece of paper.

In this activity, learners thread gumdrops together to make a model of a polymer.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this activity, learners use marshmallows and gum drops to construct seven models of molecules. Learners classify (solid, liquid or gas) and draw diagrams of the molecules.

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

In this activity, learners get hands-on with geometry by making a polyhedron kitty sculpture.

In this activity, learners build a scale model of the solar system using a roll of toilet paper.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.

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

This activity introduces learners to the structure and properties of carbon nanotubes.

In this activity, learners use pegboard and straws to build a three-dimensional model of the periodic table.
