In this activity, learners explore mammal locomotion by constructing flipbooks.

Walk On Water Bugs
Source Institutions
In this activity (on pages 29-35), learners examine water pollution and filtration.

Make An Impact
Source Institutions
In this hands-on activity, learners simulate the crashing and smashing of a meteor impact using household cooking supplies.

Games of Chance and Brains
Source Institutions
In this activity, learners build and play three math games. In the first game, called "Switcheroo," learners place marbles in holes 1 through 4 and 7 through 10.

Make an Animation
Source Institutions
In this activity, learners make a device called a phenakistoscope, which displays a continuously looping animation consisting of images drawn onto a spinning disc.
Multiple Reflections
Source Institutions
In this activity, learners explore how mirrors reflect light and change the way we see things.
Cycles in the Cards
Source Institutions
In this "game," learners explore and relate the evolution of stars to a Navajo creation story. The story is written on a series of cards, which are laid on a table as the story is told.

Chromosome Models: Karyotyping
Source Institutions
This activity was designed for blind learners, but all types of learners can have a tactile opportunity to construct a karyotype, an organized model of an organism’s chromosomes, conveying the chromos

What's Your Blood Type?
Source Institutions
In this activity, learners perform a simulated blood test procedure.
Crystal Garden
Source Institutions
Visitors observe a tray holding a crystal-covered brick. The crystals were created by evaporation of a solution containing liquid bluing, ammonia, and salt.

Charge and Carry
Source Institutions
In this activity about electricity, learners produce a spark that they can feel, see, and hear. Learners rub a Styrofoam plate with wool to give it an electric charge.

CD Spectrometer
Source Institutions
In this activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.

Inflate-a-mole
Source Institutions
In this activity, learners conduct an experiment to find the volume of one mole of gas. Learners capture sublimated gas from dry ice in a ziploc bag and use water displacement to measure its volume.

Build a Fruit Fly Trap
Source Institutions
In this construction activity, students use a 2-liter bottle to build a fly trap.

Powder Particulars
Source Institutions
In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.

Metal Noise Maker
Source Institutions
In this activity, learners explore how sound travels through solid objects better than through air. Leaners attach a metal clothes hanger to a piece of string and hold it to their ears.

Fly a Hot-Air Balloon
Source Institutions
Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.

Polarized Sunglasses
Source Institutions
In this activity, learners explore how polarizing sunglasses can help diminish road glare.

Does Your Chewing Gum Lose Its Flavor?
Source Institutions
Each learner chews a piece of gum until it loses its flavor, and then leaves the gum to dry for several days.
Shrinkers
Source Institutions
Visitors use heat to shrink samples of polystyrene. They compare samples from containers that were shaped in different ways during manufacturing.
