Water Chemistry Lesson Plans
By Subject and Grade Level
Lower Elementary - Grades K-3
Diffusion and Osmosis (K-8)
How different kinds of solutions move through selectively permeable membranes and understand the role of osmosis in the movement of molecules (2)
Make sugar solutions and determine the sweetest of these by taste. (2-3)
Upper Elementary - Grades 4-5
Which paper towel is the most absorbent and the best cost for their money? (4-6)
Diffusion and Osmosis (K-8)
Students will observe the change in density by using a variety of different objects to make them float, sink, or suspend in various liquid solutions. (4-5)
Distinguish among evaporation, condensation, and precipitation phases of the water cycle. (5)
The freezing point of water and the meiting point of ice (4-5)
Discover factors affecting the rate of solution. (K-12)
The difference between a soluble and an insoluble solution, how to increase solubility, make a saturated solution using solvents at different temperatures. (5)
What effect salt has on ice. (4-5)
Middle School - Grades 6-8
Salinity of water affects the buoyancy of ice when the water is frozen. (6-8)
Does frozen water take up more space than liquid water? (6-8)
Does water get denser when you add salt or sugar? (6-8)
How does detergent change the way water acts? (6-8)
The Relationship Between Salinity and the Density of Water (6-8)
Diffusion and Osmosis (K-8)
Discovering Cohesion, Adhesion and Surface Tension (6-8)
Does a bubble always form a sphere? (6-8)
The temperature of water affects its density. (4-6)
Demonstrate forces of adhesion and cohesion and equilibrium density. (6-8)
Water is one of the few substances that expands as it freezes. (6-8)
Weather: cloud formation, moisture, reading a thermometer, freezing and boiling points, air pressure. (6-8)
The concept of the molecule and create a model of a water molecule. (5-8)
Demonstrate freezing point depression, one of the colligative properties. (6-8)
Demonstrate that water molecules are strongly attracted to one another and thus create surface tension. (6-8)
How temperature is related to evaporation. (6-8)

How the pressure affects the boiling point of a liquid. (9-12)
Surface Tension of Water (9-12)
Distinguish between concentration and solubility and tell which solution is more concentrated. (9-12)
The Water Cycle (9)
Understand the chemistry of soap bubble films. (9-12)
Physical parameters of salinity and elevation/depth in a salt marsh (9-12)
Determine the presence of sugar using Fehling's Solution (9-12)
