In this activity, learners discover how geologists use stratigraphy, the study of layered rock, to understand the sequence of geological events.

In this activity, learners make "solar cookies," edible models of the Sun's outer layers using sugar cookies and toppings.

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

Your heart pumps blood throughout your body in one direction, around in a loop. In this activity, learners will make a model of one type of heart chamber called a ventricle.

In this activity, learners explore how the hull shape impacts a ship's performance and stability.

In this activity, learners create a "Jam Jar Jet" based on Francois Reynst's discovery of a pulsejet engine, which uses one opening for both air intake and exhaust.

This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

In this activity, dry ice and other items are used to construct a demonstration model of a comet that illustrates the comet nucleus, coma, and tails.

In this lesson, learners develop a robot arm using common materials. Learners explore design, construction, and teamwork, as well as materials selection and use.

In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.

In this activity on page 3 of the PDF, learners visualize the relative size and structural differences between microbes that have the potential to cause disease.

In this activity, learners discover how NASA engineers develop experimental aircraft.

In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

In this outdoor activity, learners use artificial bees and paper models of flowers to find out how bees transfer pollen from one flower to another.

In this activity, learners work in NASA teams to build balloon-powered rockets using identical parts and compete to launch the greatest number of paper clips to "space" (the ceiling).

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

In this activity, learners build a nanorover model using styrofoam meat trays and a balloon.

In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.
