High schoolers engage in a activity that is concerned with the water cycle and different states of matter. They conduct research using a variety of resources in preparation for taking a quiz. Then students take the quiz in correlation to...

Students investigate the states of matter. In this physics lesson, students use water and ice to demonstrate the characteristics of a solid and liquid. Students record their observations as the state of the water changes.

Students observe what happens to water as it goes from a solid to a liquid.  In this exploratory lesson students gain an understanding for the water cycle while working in groups observing what happens to water as it changes...

Students explore the states of matter. In this physical science lesson, students observe what happens to water when it freezes and record observations. Students then observe ice when it melts and record observations.

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-lesson 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, find its load line...

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...

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...

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.

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...

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...

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 lesson from PBS's Weather and Climate series for high schoolers. Scholars...

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

Young scholars compare the densities of different liquids. For 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.
