In this optics activity, learners make a lens and explore how the eye manipulates the light that enters it.

In this environmental activity (page 16 of the PDF), learners will calculate the amount of energy they save by recycling paper, plastic, glass, and aluminum materials over the span of a week.

In this activity, learners collect worms and then observe how they move.

In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).

In this activity, learners examine their tongue and taste buds.

In this activity, learners create a "mini sky" in a glass of water in a dark room.

In this activity (on page 2) about fingerprint analysis, learners use graphite from a pencil and scotch tape to capture their fingerprints.

Visitors add drops of copper sulfate solution onto a steel nail. They observe the nail change color from silver to brown as the copper plates onto the nail.

In this activity, learners explore their eye pupils and how they change.

In this activity, learners discover that our hands are not reliable thermometers.

In this activity, learners draw natural objects to explore the details, differences, and similarities of natural objects.

In this activity related to light and perception, learners use a pinhole in an index card as a magnifying glass to help their eye focus on a nearby object.

In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.

This activity gets learners looking at 6-sided shapes in nature, including the cells of a beehive, as well as other shapes.

In this playful activity, learners explore the structure of the cell—the basic unit of every living organism—by creating a model of cell structures using soap bubbles, and by examining a slice of onio

In this activity, learners explore the concept of how engineering has made possible the development of--and ongoing improvements to--adaptive devices that serve to help individuals with a wide range o

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

This activity teaches combustion as the interaction of a fuel source and oxygen.

In this on site "field trip" activity (located on pages 6-9 of PDF), learners get hands-on experience identifying building materials by playing "Building Bingo".

In this math activity, learners use a variety of sensory modalities to gain experiences with identifying, describing and creating repeating patterns.
