In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

In this activity, learners create a soil and water model of a single-cell life environment and study living microorganisms.

In this activity about humans and space travel (page 1 of PDF), learners compare and contrast the behavior of a water-filled plastic bag, both outside and inside of a container of water.

In this activity (12th activity on the page), learners conduct an experiment to demonstrate how muscles are constantly feeding information to the brain about what they are doing.

In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.

In this activity about the circulatory system and space travel (on page 38 of the PDF), learners use water balloons to simulate the effects of gravity and microgravity on fluid distribution in the bod

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

In this activity, learners create a sealed, mini ecosystem that supplies freshwater shrimp with food, oxygen, and waste processing for at least three months.

In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

In this outdoor activity/field trip, learners locate and study plants and animals in several freshwater pond habitats.

In this drawing/mapping activity, learners design plots of land while incorporating positive strategies for improving water quality.

Learners create a model of a wetland to observe how it absorbs and filters water from the environment.

This three-part lab helps learners understand the essential principles governing diffusion and osmosis.

In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

In this multi-part activity learners examine non-point water pollution.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

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

In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien
