Have your class predict whether objects will sink or float in water. Learners consider a data table of mass, volume and whether the object sank or floated. They develop an evidence-based explanation for the results.

This open-ended boat building exercise is meant to be part of a three-instructional activity series on ships. Links to the other two lessons are included. This particular part is mostly a group lab activity in which they build a boat,...

There are three separate lessons within this resource that can be used together, or that can each stand alone. In the first, five simple activities allow junior scientists to examine the amazing properties of water. In the second, they...

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...

The first golf balls were made of wood and would only last for a few games. Modern golf balls last a lot longer but they don't float. The presentation provides the directions for a lab to determine the minimum amount of salt needed to...

Learn why what goes up must come down in both air and liquids. Investigators discover how convection transfers thermal energy and the movement of particles in liquids and gases due to density differences by viewing an animated video....

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.

Pupils 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...

Students 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.

Why do some things float and others sink? A creative simulation allows learners to adjust mass and volume of an object to affect its buoyancy in water. A graph records the effect of each manipulation.

In this density of materials worksheet, students examine ways to sort a dump truck of recycled materials using the density of the material types. Students write a letter to the city council to describe their method of sorting.

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...

Fifth graders complete a worksheet which has them place a list of gases in order from the least to the most dense. The density in grams is given for each. There's a good paragraph which provides background knowledge about the volatility...

Students 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...

High schoolers read about the Spitzer Space Telescope and the technology used to learn about planet composition. They calculate the radius of a planet, the size of a planet, the average density of a planet and the likely core composition...

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 instructional activity from PBS's Weather and Climate series for high...

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.

In this ocean water and life instructional activity, students match the vocabulary term with the correct definition. Also, students answer questions by deciding if the statements are true or false. Finally, students complete concepts...

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