Learners use Duplo bricks to build antibodies with shapes that match model viruses.

In this activity, learners test the pH of safe liquids available at home by creating a pH indicator from mashed blueberries.

In this activity, learners look at and touch marine animal skulls to compare them and think about what they eat.

Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.

In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

In this activity, learners are challenged to calculate their own weight on various planets using a scale and calculator. Older learners may be challenged to do so without using calculators.

In this activity, learners separate the components of Gatorade using a home-made affinity column.

This activity encourages visitors to build an electroscope—a simplified version of one of the tools scientists use to study the invisible forces on Earth and in space.

Molecular gastronomy is the scientific study of food preparation. Learners use self-assembly techniques to create edible capsules of chocolate syrup (food grade ingredients are required).

"Molecules in Motion" explores how materials behave and change in a vacuum.

Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black.

In this activity, learners use coverslips to collect organisms from a pond, estuary or marine environment and then examine what they have caught with a microscope.

In this activity, learners bake cookies by following different recipes to better understand genetic mutations. Everyone in the group bakes the same type of cookie: chocolate chip.

Build a phonograph record player using a cactus needle, a record, LEGOs gear box, and a piece of paper! This activity uses a Pico Cricket to turn the motor.

In this activity, learners explore how rescue devices are designed to aid professionals during emergency situations.

In this activity, learners explore how a hydraulic pump works. Learners work in teams to design and build a unique water fountain that employs a hydraulic pump.

In this activity, learners explore sports engineering and advanced materials development.

In this activity, learners explore the concept of how engineering solved the problem of human/computer interface.

In this activity, learners are challenged to design and build a miniature tree house in a potted plant. This activity uses engineering concepts to encourage creativity.

In this activity, learners explore the many uses of periscopes and how this simple device was designed and is used in many applications.
