Water Tower Challenge
Source Institutions
In this activity, learners explore how engineers work to solve the challenges of a society, such as delivering safe drinking water.

Sticky Engineering Challenge
Source Institutions
In this activity, learners explore how engineers work in a team to solve problems.

Wind Tunnel Testing
Source Institutions
In this activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.

Air Pressure and Dent Pullers
Source Institutions
In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

Chemistry Makes Scents
Source Institutions
In "Chemistry Makes Scents," participants use their noses to distinguish between chemicals with very similar structures.

Pages of a Forbidden Tome
Source Institutions
In this activity, learners use chemistry to produce weathered "antiqued" paper with burned edges. Learners first soak white paper in coffee and then apply a charring solution of ammonium chloride.

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

Making Sense of Sensors
Source Institutions
In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

Pendulum Snake
Source Institutions
In this physics activity, learners assemble and/or investigate a pendulum "snake." Several large steel hex-nuts are suspended on strings of successively increasing length to form a series of pendulums

Antibody Builder
Source Institutions
Learners use Duplo bricks to build antibodies with shapes that match model viruses.

Exploring the Universe: Static Electricity
Source Institutions
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: Use Self-Assembly to Make a Dessert Topping
Source Institutions
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
Source Institutions
"Molecules in Motion" explores how materials behave and change in a vacuum.

Build Your Own Solar Oven
Source Institutions
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.

Our Sense of Sight: Eye Anatomy and Function
Source Institutions
In this activity, learners investigate the sense of sight and develop and conduct their own experiments.

Exploring Black Holes and Gravity
Source Institutions
This fun and simple hands-on astronomy activity lets learners imagine what would happen if our Sun were replaced with a black hole.

Waterproof that Roof!
Source Institutions
In this activity, learners explore how engineers have improved roofing designs and materials in order to protect the contents of buildings.

Statue Display Tower
Source Institutions
In this activity, learners design, build, test and redesign a display tower that will meet a specific set of criteria and constraints.

Mapping a Study Site
Source Institutions
In this outdoor activity, learners use a mapping technique to become oriented to the major features of an outdoor site.

Life Size: What's in a microbe?
Source Institutions
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.
