Red Cabbage Chemistry
Using the natural pH indicator of red cabbage juice, groups determine the pH of different everyday liquids. As they work, pupils gain an understanding of pH that may help deal with contaminants in the water supply.
Exploratorium
Indicating Electrolysis
Sure, your learners know water is made up of two molecules, but watching them separate helps the class see the construction like never before. This resource provides directions on how to build a simple electrolysis device using a...

Wetting and Contact Angle
Explore terminology related to water droplets. The sixth installment of a nine-part series teaches young scientists about wetting and contact angles between water droplets and surfaces. It also distinguishes between hydrophobic and...
LABScI
Surface Tension: Liquids Stick Together
Use science to help you walk on water! Young scientists explore the properties of liquids including cohesion, adhesion, and surface tension. They use graphs to compare different liquids and make predictions about their molecular attraction.

The Water in Our Lives: Kit Practice
Students examine a local water source using testing kits to determine water qualitiy. They identify the pollutants and contaminants in each sample. They determine if samples fall within an acceptable range for drinking water.
Discovery Education
Sonar & Echolocation
A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...
Cornell University
Non-Newtonian Fluids—How Slow Can You Go?
Children enjoy playing with silly putty, but it provides more than just fun. Young scientists make their own silly putty using different recipes. After a bit of fun, they test and graph the viscosity of each.

Melting Ice
Students observe the melting of ice and explore the basic physical changes that occur. They gain information of how different substances change the rate of melting. Students discuss the properties of water and ice, the definition of...
Curated OER
Water Pollution and Food Chains
Students investigate the two key concepts covered in this lesson: first, how pollution can affect plants, and, second, how polluted plants affect the rest of the food cycle. In sum, this lesson teaches students about "Bioaccumulation".
Curated OER
Water Quality
Young scholars investigate the properties of oil and water by making marbleized paper. They examine fish species by making Japanese fish prints and 3-D cardboard fish. They create posters that present messages about conserving our ...

Let's Think About Water
Students explore the different forms that water can take and conduct simple experiments to demonstrate some of its properties in each state. They watch a short video that illustrates some of these concepts.
Curated OER
OK...Just Whose Water Is It, Anyway?
Students recognize that each person has a right to clean, safe drinking water. They explain that changes in behavior may be necessary when considering water usage. They role play a water rights courtoom dispute.
