Students explore water properties by conducting a class experiment. In this buoyancy lesson, students utilize freshwater, saltwater, plastic cups, hard boiled eggs and food coloring to experiment with the floating capabilities of salt...

Fourth graders explore and experiment with objects that float to see if they float differently in salt water or fresh water. After the experiment, they write a paragraph in their science journal explaining how fresh water and ocean water...

Learners experiment to discover that salt water is denser than fresh water by creating color coded solutions. They examine how heavy rainstorms and high tides develop layers of different degrees of density.

Students develop hypothesis about what might happen when salt water is frozen. In groups, they freeze ice samples with different salt concentrations. They use the internet to research the situation of the Jeannette to discover their...

Students study the benefits of estuaries. They construct a saltwater food web, and complete worksheets and a quiz.

High schoolers investigate the various factors that influence the Pacific Ocean and Monterey Bay, California. They watch a video about Monterey Bay and take notes, and conduct research and write a report about a specific organism living...

Using your senses, apprehend the effects of contaminants in water. With a global focus, young scientists conduct a safe experiment by tasting sugar and salt water with different dilutions. After reviewing threshold limits, learners write...

Students explore the hydrological cycle and oceans. They determine the factors that influence the Pacific Ocean. Students research an organism found in Monterey Bay. They describe the organism's biome and ecological factors that...

Students observe a model of the distribution of the earth's water and compare the relative volumes and percentages of types of water on earth.

Students complete a unit of activities to learn about ocean life as well as improve their math and measurement skills. In this ocean life and math skills lesson, students complete 8 lessons to learn about ocean life and complete...

Middle schoolers 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...

Students create a poster describing the five characteristics of a salt water organism compared to a fresh water organism.

Students observe how different water densities control the depth at which different water masses occur. They explain one fact that they comprehend about salt water. Students comprehend that temperature and salinity affect the density...

Your mission, should you choose to accept it, is to take your class on an underwater adventure. The final installment in a seven-part series involving salt and freshwater bodies takes junior oceanographers below the surface in...

Water is the focus of an interdisciplinary unit that brings awareness to its daily use around the world and the importance of conservation. Worksheets challenge scholars to match words and definitions, trace, complete a maze, and solve a...

Students identify locations of coral reefs, both in the water and around the globe, identify relative depth of corals in the ocean by observing behavior of cold and warm saltwater, and create models of coral reefs.

Learners examine the reasons why metal corrodes in regard to metal artifacts. In groups, they discover the affects of salt water on metal and compare the type of corrosion found on iron. They also research the types of metal...

Students define wetlands. They list the benefits wetlans provide to man and nature. They compare types of wetlands that exist in northeast or east-central Florida. They list ways uplands affect wetlands and other water bodies.

Students define groundwater. They identify groundwater's relationship to springs, artesian wells, ordinary wells and sinkholes. They describe the process by which sinkholes are formed. they define saltwater contamination and explain its...

Students watch a video about aquatic communities. They conduct an experiment that shows how movement of rivers change the landscape. They compare fresh and salt water communities and its wildlife.

Sixth graders classify candy according to observable characteristics. They use a dichotomous key to identify their bag of "treats." Thus, describe how dichotomous keys help to the identifying of organisms. Design a self-generated...

Students investigate the water cycle by viewing an online video.  In this drinking water lesson, students create solar stills at their campus in order to purify water that is tainted.  Students view a video on their computers...

When your upper elementary or middle school class is learning about chemical changes, these activities help demonstrate the concepts. In Part A, they submerge and place a nail partially underwater, then after a week they make...

Ninth graders conduct research on the subject of sea water. They use a variety of resources to obtain information. There are helpful resource links listed in the lesson. In conjunction with the research students make inquiry of the...
