Soda Pop Cave
Source Institutions
In this geology activity (page 6 of the PDF), learners explore how carbonic acid can slowly dissolve limestone and form caves.
Water, Water Everywhere
Source Institutions
In this activity, learners estimate how much water they think can be found in various locations on the Earth in all its states (solid, liquid, and gas) to discover the different water ratios in the Ea
Build A Hydrometer
Source Institutions
In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.
Super Soaking Materials
Source Institutions
In this activity, learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.
The World's Water
Source Institutions
Water on Earth is in lakes, the ocean, rivers, underground, and frozen glaciers.
Do Sweat It!
Source Institutions
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.
Super Soaker
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.
"Boyle-ing" Water
Source Institutions
In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.
Cleaning Water with Dirt
Source Institutions
In this activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.
Sand Castle Saturation
Source Institutions
In this activity about saturation (page 1 of PDF under SciGirls Activity: Sand Dunes), learners will build a series of sand castle towers using a 16 oz cup.
Exploring Forces: Gravity
Source Institutions
In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.
Heat Capacity: Can't Take the Heat?
Source Institutions
Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.
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.
Ocean Currents
Source Institutions
In this activity, learners will explore how density is affected by temperature and how that can create currents.
Cohesion Coin
Source Institutions
In this activity about the property of water (page 6 of the PDF), learners use a coin to demonstrate cohesion between water molecules, exploring the molecular forces that allow water molecules to "
