Electrolysis of Water
Young scientists know that water is H2O, but can they prove it? Through a simple electrolysis of water demonstration, scholars see the two gases produced as a result of a chemical reaction. Because this reaction doesn't happen...

Surface Water and Groundwater
Students examine distribution of water and minerals. In this surface and groundwater instructional activity, students conduct an experiment with fresh and salt water making hypothesis and drawing conclusions about minerals.
Curated OER
Water Pollution Prevention and Conservation
Students examine how to conserve water. They also discover how to prevent water pollution. They examine the Earth's water distribution as well.

Properties of Salt
Students see how the properties of salt affect the color of flame, the flow of electricity, and the freezing temperature of water. They identify salt and sugar crystals under a microscope and discuss various practical uses of salt.

Splish! Splash! From the Bath to my Glass
An excellent lesson on the water cycle! In it, learners should gain a general understanding of the water cycle, along with how water first falls as precipitation, then ends up coming out of our faucets. This lesson nicely integrates...

Amazing Salt
Learners examine the effects of salt on ice. For this salt lesson, students observe what happens to the temperature of ice when salt is added, then make ice cream to see how this knowledge can be used.

CHM 152-Acids, Bases and Salts (Chptr. 14)
In this acids, bases and salts worksheet, students answer sixty three questions about ionization, pH, pOH, strong acids and bases, equilibrium and salts. They write formulas for acids and bases, they identify conjugate acids and bases...
Curated OER
Contaminated Drinking Water
Students predict, experiment, and draw conclusions about the safety of drinking water. In this ecology lesson plan, students participate in an experiment to determine if they can taste or see contamination in drinking water. Data is...

Why is a salt marsh important?
Middle schoolers discuss the salt marsh. They define the following terms: habitat, water, land and air. Students work in small groups. They are asked why are they going to a salt marsh? Middle schoolers discuss whose habitat is it at...
