Changing the Water in the Aquarium
Students discover the importance and how to change the water in an aquarium. As a class, they review the types of impurities that are found in water and discuss how to keep the tank as clean as possible. They develop a water change...
Curated OER
Water Quality
Students examine the YSI and the water properties that it measures. They identify the different properties of water pH, DO, temperature, turbidity, and salinity and determine why it is important for them to test these parameters.
Curated OER
Water Pollution
Fifth graders examine what contaminated water looks like, and how it becomes polluted. They examine a teacher demonstration of water is not polluted but does contain rocks and other things that do need to be cleaned out before drinking...

Clean Kansas Water
Students gain an understanding of ways we can be responsible custodians of our water supply. Students explore the governor's clean water initiative involving the Lower Kansas/Republican river basin and the pollutants present there.
Curated OER
Wide Open Spaces
Students examine the problem of groundwater pollution. In groups, they develop a solution to solve the problem of a local polluted water source. They also practice measuring the space between sediment particles and the rate of water flow.
Curated OER
Wacky Water Critters
Young scholars visit a local creek or stream. They collect water samples from the creek and observe and sort the "water critters" they find in the sample, observing smaller organisms under a microscope if necessary. They identify each...
Curated OER
Leaking Underground/ Storage Tanks
Young scholars engage in a lesson that is about the concept of storage tanks and how they are used. The advantages and disadvantages of them is discussed with the facts given by the teacher during lecture and concurrent discussion.
Curated OER
Salinity and Brackish Water Systems
Students are able to tell the difference between brackish and salt water. They also are able to distinguish water qualities specific to each type of water. Students answer various questions about all types of water.
Curated OER
Creating a Pond Habitat
Students create a pond habitat inside and outside their classroom. In this pond lesson plan, students create a habitat with animals, water, and plants in order to create a proper pond habitat.
Exploratorium
Blue Sky
Use a container full of water as a prism and show that as light is bent, the individual colors from different wavelengths become visible. This explains why the sky appears to be blue midday, and why as the sun nears the horizon, it looks...
American Chemical Society
Defining Density
Three simple activities kick off a unit investigation of density. Your physical scientists make observations on the volume and mass of wood, water, and rocks, and make comparisons. Though this is written for grades three through eight,...
Curated OER
Controlling Nonpoint Source Pollution
Learners examine factors affecting water quality. They test water in a local body of water to determine its quality. They collect data and continue monitoring the water monthly. They assess water quality in the home and on the farm.

Euler’s Number, e
Scholars model the height of water in a container with an exponential function and apply average rates of change to this function. The main attraction of the lesson is the discovery of Euler's number.
Curated OER
Cruising
Cruise ships offer many engaging opportunities for real-world math adventures. These large, floating cities use resources with numbers into the thousands place. Young mathematicians are asked to calculate numerical information relevant...
Texas State Energy Conservation Office
Investigation: Insulation
Youngsters compare the heat-holding abilities of three different cans by insulating two with different materials and measuring the temperature change of hot water over a 20-minute period.
Curated OER
"Pennsylvania Watersheds, Many Ways to the Sea"
Students trace a molecule of water through the water cycle including each of its three loops. They describe why evapotranspiration demands the largest portion of total precipitation falling on a forested watershed.
Curated OER
Dive Right In
Students make a submarine from a two liter bottle to observe the effects of increased water pressure in deeper water. They discover that water has weight and can cause objects to submerge.
Curated OER
The Tank
Students have a better grasp of the ecosystem of the St. Mary's river. They analyze how the tank is meant to be a miniature of the river. Students inquire how to take care of the tank and its inhabitants. They are introduced to Fundulus...

Tippy Tap Hand Washer
High school physics or engineering classes construct a system for piping water from a storage tank to a water dispenser. They will apply Bernoulli's principle and perform calculations for elevation, pressure, and velocity. This is a...
Curated OER
Count Marsili & the Mediterranean Current
Students integrate history and science while discovering how salinity affects the density of water. After a lecture/demo, students work in groups to complete a lab activity that demonstrates how salinity affects the density of water.
