Thirsty Candle
Source Institutions
In this activity, learners will explore the dynamics of air pressure by using a candle, a cup, and a dish of water.

Weightless Water
Source Institutions
In this physics activity (page 5 of the PDF), learners will witness the effects of free fall by observing falling water, and will gain a better understanding of the concept of weightlessness.
Investigating Density Currents
Source Institutions
In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).
Up, Up and Away with Bottles
Source Institutions
In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.
It's A Gas!
Source Institutions
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.

Spill Spread
Source Institutions
In this simulation, learners explore how ocean currents spread all kinds of pollution—including oil spills, sewage, pesticides and factory waste—far beyond where the pollution originates.

Collect Invertebrates to Determine Water Quality
Source Institutions
This activity (located on page 3 of the PDF under GPS: Alligator Habitat Activity) is a full inquiry investigation into organisms and the health of their ecosystems.

That Sinking Feeling
Source Institutions
In this quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.

What Causes Wind?
Source Institutions
In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

Turbidity
Source Institutions
This is an activity about turbidity, or the amount of sediment suspended in water.

Exploring an Ecosystem
Source Institutions
In this ecology activity, learners make a model water-based ecosystem called a terraqua column. The column (in a large soda bottle) includes pond water, duckweed, sand or gravel, and small snails.

Diving Submarine
Source Institutions
Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

Handwashing Laboratory Activities: Bowl Technique
Source Institutions
In this lab (Activity #2 on page), learners compare bacteria growth on two petri dishes containing nutrient agar. Learners touch the doors, faucets, etc.

Gravity Fountains
Source Institutions
This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

Fireworks in a Glass
Source Institutions
In this activity, learners use water, oil, and food coloring to observe a chemical reaction that creates a shower of colors inside of a glass.

Static Water
Source Institutions
In this activity, learners will use static elecricity to bend a stream of water without touching it. Learners will explore physics and cause and effect through this activity.

Tie Dye Secret Messages
Source Institutions
In this activity, learners will write a secret message that only their friends will be able to read.

Using Solar Energy
Source Institutions
In this activity, learners discover how solar energy can be used to heat water.

Draggin' Boats
Source Institutions
Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

Irrigation Ideas
Source Institutions
In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.
