The Chesapeake Bay is the largest estuary in the United States. Explore its origins, organisms, and contributing rivers with this PowerPoint. It opens with several slides of general information on the formation of estuaries, then it...

Students will observe the amount of water in an open container over time and also examine the amount of water in a closed container over time. They then will compare and contrast the sets.

Here is a wonderful series of lesson plans that use celery to faciliate all sorts of learning. By the end of the lessons, youngsters should know how celery is grown, how celery is used in homes and restaurants, and they will understand...

Lab groups fill a section of dialysis tubing with glucose and starch solutions and suspend it in a water bath. They use iodine as a starch indicator and a glucose test strip to find out if either of the materials crossed the selectively...

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...

If the world were 100 people...17 would not have access to safe drinking water, 18 would not be able to read or write, and 52 would not have a primary education. Using the theme of "100 people," this resource explores other major issues...

Your youngsters become cheetahs in search of food, water, shelter, and space in a fun physical game that does a fantastic job of representing fluctuating species population based on resources available over years. 

In this solutions worksheet, students identify solutes and solvents from a list of solutions and they draw water molecules bonding to each other. They fill in the blanks with terms related to bonding in solutions, density of solutions...

Placing a thermometer and a glass tube into a flask of cold water and sealing it, you can expose it to heat and very visually demonstrate thermal expansion to your earth science class. Follow it with a discussion about how the increasing...

Buoys around our coastlines are equipped with sensory devices which monitor temperature, salinity, and water pressure. Emerging earth scientists examine some of this data and relate salinity to the electrical conductivity of the surface...

Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

Learners examine a painting.  In this shapes and puzzle lesson, students view Guston's painting Blue Water and identify the colors, shapes and recognizable forms.  Learners work in groups to put together puzzle pieces of the...

In this solutions worksheet, students answer questions about the solubility of various substances in solvents such as oil in water and nitrogen gas in helium. They draw water molecules to show bonding between them and they diagram a...

Middle schoolers debate one another. In this pollution lesson, pupils work in teams to debate which is more serious, air or water pollution. They research their topic to come up with valid points to justify their side of the debate.

Here is a fascinating topic: the upwelling of ocean waters. Oceanography pupils learn what mechanisms cause upwelling, types of upwelling, and the effects on marine life. Colorful satellite imagery and informative diagrams bring this...

Future chemists practice laboratory techniques by creating a monochloramine solution. The objectives are to use of dilution, 9concentration, and measurement skills and to prepare a solution that will be used in a water treatment...

Use the classic density demonstration of placing a cola, a clear soda, and a diet soda into a tank of water. Then let learners attempt to pour some of the soda into layers in a clear container. The procedure explains a thermocline, and...

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. 

Is the ocean blue at all depths? Nope! Explore the science behind the light spectrum in deep, dark waters. The lesson recommends watching The Blue Planet: Open Ocean—The Deep, but it's not integral, or you can substitute another clip....

What do plate tectonics and ocean currents have to do with global climate? This fourth installment in a six-part series focuses on how plate tectonics and ocean currents affect global climate, both now and in the past, outlines an...

Scholars collect data from heating sand and water before forming testable hypotheses about why sand heats up faster. Afterward, they develop and run experiments to test their hypotheses.

Students make a holiday or seasonal snow globe to give as a gift. Make it, then shake it! Students use small jars with lids. They use a glue gun or silicon glue to attach a small plastic toy to the inside of the lid. When the glue is...

The fascinating video "Changing Planet: Fresh Water in the Arctic," introduces your oceanographers to the world's gyres. They learn that melting sea ice is making the gyres larger, and that the changes could, in turn, contribute even...

What does math have to do with a sore throat? When you mix water and salt you have a great review of how to represent proportional relationships by an equation or graph. Here the proportions of the mixtures may be different, but the...
