In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.

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

Each learner chews a piece of gum until it loses its flavor, and then leaves the gum to dry for several days.

In this activity, learners will explore how metals react with each other. They will see these metals change before their eyes as they coat a paperclip with the copper taken from a penny.

Visitors use heat to shrink samples of polystyrene. They compare samples from containers that were shaped in different ways during manufacturing.

Visitors incrementally increase the amount of iodate in three different test tubes containing the same amount of a starch solution.

Our bodies defend themselves in many different ways to prevent us from getting sick.

In this activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.

In this activity, learners explore how molecules must fit together, like a lock and key, in order to identify each other and initiate a new function as a combined unit.

In this experiment, learners examine the way oil affects bird feathers and test different cleanup methods to find out which works best.

In this activity related to plant biotechnology, learners use restriction enzymes to cut up DNA from a virus called Bacteriophage λ, a process known as restriction digestion.

In this activity, learners will explore vegetative propagation while preparing food scraps to grow into plants.

In this activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.

This laboratory exercise is designed to show learners how DNA can easily be extracted from yeast using simple materials.

In this activity, learners use Teflon (PTFE) tape to write secret messages.

Learners are challenged to create solutions that conduct electricity and make a buzzer buzz (or an LED light up).

In this activity, learners participate in several full-body interactive games to model the process of self-assembly in nature and nanotechnology.

In this activity on page 7 of the PDF, learners experiment with the interesting designs that can be made by painting on plaster.

In this chemistry activity, learners use common chemicals to examine reactions that occur between two aqueous solutions.

In this activity, learners identify the DNA base bars guanine, cytosine, thymine and adenine. Learners create a DNA model using colored paper clips to resemble these base pairs.
