In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.

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

In this activity, learners explore the function and engineering of dams and how dams have many uses and solve many problems in the world.

In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

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.

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.

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

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

Using simple, inexpensive items, learners build and test submarine models.

Learners take a field trip along a local body of water and conduct a visual survey to discover information about local land use and water quality.

In this archaeology meets art activity, learners make a mosaic and consider the ways in which art communicates.

This fun and simple hands-on astronomy activity lets learners experiment with a bucket, stretchy fabric, marbles, and weights to discover some basics about gravity.

In this activity, learners explore the magnetic field of a bar magnet as an introduction to understanding Earth's magnetic field. First, learners explore and play with magnets and compasses.

Water on Earth is in lakes, the ocean, rivers, underground, and frozen glaciers.

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.
