In this activity related to plant biotechnology, learners extract DNA from fruit to investigate how it looks and feels.

Learners investigate how temperature affects the rate of chemical reactions by observing how steel wool reacts with various types of Kool-Aid solutions at different temperatures.

This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells. It includes an optional test for the presence of DNA.

In this activity about osmosis, learners use a naked egg (one with a dissolved eggshell) to learn about selectively permeable membranes.

This is a chemistry lab activity about solutions (page 7 of the PDF). Learners see firsthand how chemicals in a solution can combine to form an entirely different substance.

In this optics activity, learners explore how they can make gelatin stop light, but not stop them from seeing fruit suspended within.

In this activity/demo, learners are introduced to the connection between medieval stained glass artisans and nanotechnology.

In this experiment, learners float colored ice cubes in hot and cold water.

Learners experiment with water gel crystals, or sodium polyacrylate crystals, which absorb hundreds of times their weight in water. When in pure water, the water gel crystals cannot be seen.

In this quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.

In this activity, learners review and discuss weathering, erosion and mass wasting, to gain a stronger understanding of how Hickory Run’s Boulder Field was formed after the Laurentide Continental Glac

In this outdoor activity, learners compare the moisture released from different kinds of leaves and from different parts of the same leaf, by observing the color change of cobalt chloride paper.

In this plant science activity, learners conduct four experiments to observe how plants respond to sunlight and gravity.

In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.

“Exploring the Solar System: Ice Orbs” is a hands-on activity in which visitors investigate a frozen orb, trying to learn about objects hidden inside.
