Third graders complete a unit of study about the water cycle using both print and Internet based resources. They examine fresh and salt water and complete an online quiz before developing a multimedia presentation highlighting the phases...

Here is a document full of teaching notes on water quality and bodies of water that you can use in your ecology curriculum. It has information specific to the Hudson River area, but can easily be adapted to any local body of water....

Students consider how long humans can live without water. They compare the weight of dried and fresh food. In addition, they trace their bodies and color portions to represent the amount of water their bodies contains.

Young scholars compare and contrast the properties of salt water in the oceans/seas and freshwater elsewhere on the planet. They also analyze mixing caused by currents in the ocean, including the effects of warm and cold water as well as...

Students answer short answer questions about the water cycle and other cycles. In this water cycle lesson plan, students explore clouds, rain, evaporation, and more.

Students examine water, its function and how much you should consume.  In this water lesson students study water and why it is important, how much you should drink and what its functions are in your body. 

In this complex salt learning exercise, students create teraamminecopper(II)sulphate-1-water using copper(II)sulphate, concentrated ammonia and ethanol. Students determine the formula mass for their product, the theoretical yield of the...

Students explore water bodies on the planet Earth and their various uses and qualities. They examine several ways that engineers are working to maintain and conserve water sources and think about their role in water conservation....

Expectant earth scientists examine the bottom side of a leaf and learn the role of the stomata. They consider the gas exchange that occurs through these structures and relate how the climate is changing to its impact on food crops. This...

Learners examine water samples from a local stream. They identify various types of macroinvertebrates found in that water ecosystem and perform a quantitative macroinvertebrate survey to determine the stream's water quality.

Students use a globe and cups of water to illustrated the amount of water versus land on earth and the amount of fresh versus salt water available to plants and animals.

Students examine brackish water. In this Science activity, students observe organisms found in brackish water. Students record their observations of the various organisms.

Fourth in a set of several little lessons on density, this one compares the density of fresh and salt water. First by demonstration, and then by a hands-on activity, learners find that adding salt increases the density, as is evidenced...

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...

Students study thermal energy and energy transfer to sea ice processes. In this energy transfer instructional activity, students make their own ice cream and discuss energy transfer and thermal energy. Students view a radiation overhead...

Meteorology or earth science classes reach for the sky with this lesson plan! You will need to purchase a Fizz Keeper® device and temperature strip for each lab group if you want them to perform this as an activity rather than you doing...

Students answer the question, 'Should San Diego reclaim its water for fresh drinking water?' They make a poster explaining the position: "Yes," drink reclaimed water; or "No," don't drink reclaimed water.

Students perform simple and fun experiments to use the scientific method, take careful notes, and write a lab report. They first make and test a hypothesis about how many drops of water they can fit on the face of a penny and then test...

Students examine the different parts of a plant and each ones role.  For this exploratory lesson students complete several activities including a game of charades.

Students study salty and fresh waters.  In this harbor estuary lesson students complete a lab activity on salinity and describe what happened. 

Students list characteristics of wetland and describe the functions of a wetland.

Plankton: so much more than just a SpongeBob character. Three different activities have kids looking at both phytoplankton and zooplankton in pictures, as well as collecting their own samples (depending on your access to a saltwater...

Learners become familiar with real-world gathering of chemical data. The experience how the science is done: the nature of analysis, data collection, interpretation, and presentation. They study a nearby body of water for their experiment.

Students conduct an experiment using a small sample from a local water source. They introduce fertilizers and pesticides, separately, and carefully examine the results in their simulated aquatic ecosystem.
