In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.

Visitors mix water and sodium bicarbonate (baking soda) in a large flask. They then add citric acid to the mixture and stopper the flask. The resulting reaction creates carbon dioxide gas.

April showers bring May flowers, but what do coastal storms bring?

Visitors separate a mixture of pebbles, salt crystals, and wood shavings by adding water and pouring the mixture through a strainer.

Visitors mix urea with water in one flask and mix calcium chloride with water in another flask. They observe that the urea flask gets cold and the calcium chloride flask gets hot.

Visitors prepare six solutions combining vinegar and ammonia that range incrementally from acid (all vinegar) to base (all ammonia).

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.

Learners make their own paper. They start by shredding old newspaper, clean toilet paper, and clean paper towels.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

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, learners explore clouds and how they form.

In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.

In this environmental health activity, learners investigate their own vital lung capacities.

In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.

In this activity, learners are invited to imagine the park of their dreams!
