A Funny Taste
Source Institutions
In this activity, learners explore the different salinities of various sources of water by taste-testing.
Salt 'n Lighter
Source Institutions
In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.
Water Wire: Electricity Flowing Through Water
Source Institutions
In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.
Salts & Solubility
Source Institutions
In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.
Make a "Mummy"
Source Institutions
The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.
Test Density with a Supersaturated Solution
Source Institutions
Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.
Comparing Crystals
Source Institutions
In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.
We all Scream for Ice Cream
Source Institutions
In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.
Curious Crystals
Source Institutions
Learners carefully look at four known household crystals.
Crystal Stencil Stars
Source Institutions
In this activity on page 6 of the PDF, learners dissolve Epsom salt in water and discover that the resulting solution can be used to create a work of art.
Let's Go Ice Fishing
Source Institutions
In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.
Pickle Lab
Source Institutions
In this online activity, learners experience the thrill of pickle making, and explore how a cucumber becomes a pickle.
A Closer Look at Crystals
Source Institutions
In this activity, learners compare different types of salt crystals under a magnifying glass.
Build A Hydrometer
Source Institutions
In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.
