Combine science and literature with this lesson on buoyancy. Read There's an Ant in Anthony by Bernard Most to examine words containing the letters a, n, and t. Then introduce your class to the word "buoyant." Demonstrate how an egg...

We're not talking about the kitchen sink. Learners explore what types of objects sink and float in water in an inquiry-based lesson. With experimentation, they find similarities between materials that float and those that sink.

Students experiment with currents caused by temperature variations that simulate the origins and flow of polar bottom currents. They discover water density is affected by temperature and salinity, resulting in deep water currents.

Students listen as the teacher explains convection currents in the ocean. They experiment with finding a smoking match in the classroom with their eyes closed. Students discuss what might effect their ability to pinpoint the smoke...

Learners examine how salt water is more dense than fresh water through experimentation with eggs.

Students observe and experiment with the concept of density. This is done using a simple experiment that helps them to apply scientific principles of observation and proving a hypothesis.

Students investigate the effect of temperature on the density of air by putting an uncovered bottle in a bucket of hot water. Then they place a balloon over the mouth of the bottle. They repeat the procedure using ice water and explain...

Learners determine the molar mass of a gas. In this molar mass of a gas lesson plan, students use the vapor density of an organic solvent to determine its molar mass. They vaporize the solvent and collect the vapor. Once it is cooled...

Another A+ lesson on the impact of climate change comes to you from the National Earth Science Teachers Association. In this installment, learners model the stratification of water in lakes due to temperature differences. The lab also...

Swirling and churning, the waters of the North Atlantic play a vital role in Earth's climate! Discover the many factors that produce circulation using a multimedia activity from PBS's Weather and Climate series for high schoolers....

Students examine how the mass of water can affect sound vibrations.

Students compare the densities of different liquids. In this liquids lesson plan, students compare color, viscosity, weight, volume, and graph their findings.

High schoolers perform a series of tests on water-based paints. In this chemistry lesson plan, students identify their different functions. They calculate paint density and fractional concentrations.

Learners explore physical science by participating in a class experiment. In this chemistry lesson, students discuss what they predict will happen when cooking oil and water are blended together. Learners utilize a plastic bottle,...

Students describe the role of density in driving deep ocean currents and the density layers of the ocean. They determine that the ocean is one continuous body of water with global currents that interact, with water surrounding all...

Young scholars investigate ways to find the density of irregular shaped objects. In this physics instructional activity, students calculate density using its mass and volume. They explain why some objects float or sink in water.

Students explore the concept of density and buoyancy. In this physics lesson, students discover the different factors that affect an object's density and buoyancy in water. Students conduct several investigations to further...

Students create a model estuary. In this modeling estuaries lesson plan, students identify characteristics and mix water of varying densities. Students form a hypothesis, conduct an experiment, and analyze the results.

Students explore the changing density of water. For this physics lesson, students investigate how an object's density determines whether it will float or sink in water. They explain why this unique property of is important to living things.

Students explore how fish are able to move easily from one depth to another in water.  In this fish lesson students create their own balloon fish. 

High schoolers examine what happens to salt water when it freezes. In groups, they measure density and salt concentrations in different samples of water and record its freezing time. They discuss the relationship between water density...

In this density worksheet, students investigate what will happen when various liquids with different densities are put into the same container. They hypothesis and make observations. Students answer 4 questions about their investigation...

Third graders conduct an experiment. In this floating and sinking liquids lesson, 3rd graders discuss density and investigate it using syrup, vegetable oil and colored water. Students observe the results and complete a worksheet.

Students investigate Archimedes' Principle and show how it relates to density. In this Archimedes' Principle lesson plan, students experiment with a beaker of water, a Styrofoam "boat" and a weight. They predict what will happen when the...
