This warm weather activity introduces learners to the impact trees have on blocking the sun's heat and reducing temperature on the Earth's surface.

In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this activity, learners make their own heat waves in an aquarium.

In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.

In this activity, learners create a biosphere in a baggie.

In this activity, learners explore why humans sweat. Learners compare the effects of heat on a balloon filled with air and a balloon filled water.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.

In this activity, learners explore how salt water freezes in comparison to fresh water.

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

In this experiment, pairs of learners explore how cold water affects circulation. The mammalian diving reflex (MDR) slows circulation when the body is exposed to cold water.

In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.

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.

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 explore how light and dark colored objects absorb the Sun's radiations at different rates.

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

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

In this activity, learners discover how sweating makes us feel cooler. Learners put on one damp sock and one dry sock and sit in front of a fan.

In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl
