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.
Shark Sense of Smell
Source Institutions
This is an activity about our sense of smell and how it compares to sharks' super noses. Learners will create varying solutions of water and perfume.
The Scoop on Habitat
Source Institutions
Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.
Glove Gardens
Source Institutions
In this activity, learners create a garden in a disposable glove. They learn about the conditions necessary to make the seeds sprout and actively participate in caring for their plants.

In this health activity (located on page 4 of the PDF), learners will discover the importance of hand washing by observing mold growing on potatoes.
Bready Bubble Balloon
Source Institutions
Learners discover the bubble power of living cells in this multi-hour experiment with baker's yeast. Learners make a living yeast/water solution in a bottle, and add table sugar to feed the yeast.
How Plants Grow
Source Institutions
