Students observe how salinity affects the time it takes water to freeze. They participate in an experiment to determine that ice is essentially salt-free whether formed from fresh or salt water

For this density worksheet, learners read a selection on density and answer 10 questions using the information from the selection.

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

Demonstrate the movement of lithospheric plates due to convection in Earth's mantle. Learners then model the movements that occur along plate boundaries using colored clay. 

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...

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 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. 

Students investigate water column data. In this earth science and seawater lesson, students determine how temperature, salinity, and density have an impact on sea water by viewing and analyzing data obtained from a number of websites....

Students construct their own submarine following a certain procedure. In this physics lesson, students calculate the density of objects using a mathematical formula. They explain why some object floats in water while some do not.

In this density worksheet, students review this property of matter and the mathematical equations for density, mass, and volume. The worksheet has 10 fill in the blank statements and 3 word problems.

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.

In this density worksheet, students use the mass of aluminum and copper at different volumes to create a graph in order to calculate the density of these metals. This worksheet has 1 graph, 2 short answer, and 5 word problems.

Students examine relationships and interactions between different types of water. They experiment with colored water of different temperature and salinity and discuss how the results relate to real ocean currents.

Second graders watch a demonstration and complete an experiment to determine how an objects' density allows it to float or sink. They work in small groups to assimilate the characteristics of items that float as opposed to simply...

In this deducing density worksheet, students follow the procedures to set up an experiment about objects floating in water and liquids of different densities, answer questions, collect data and complete charts.

Students participate in several density lab activities in order to clarify the misconceptions that solids sink and liquids float. Students work with triple beam balances to find mass of objects to calculate density.

Students consider density and how it affects sinking and floating. Students make predictions, test liquids, and observe why some liquids sink and others float. They perform experiments to determine relational causality and how liquids...

Students complete a unit on the effects of pollution on our water supply. They create a graph to examine the density of earth's land surface, round the population to the nearest hundred million place, participate in a...

How many pennies can an aluminum foil boat hold? That is the challenge in a collaborative activity designed to explore the concept of buoyancy. Learners use aluminum foil to build makeshift boats and test the weight they hold before...

In this solutions worksheet, students answer questions about the solubility of various substances in solvents such as oil in water and nitrogen gas in helium. They draw water molecules to show bonding between them and they diagram a...

Students use satellite data to see the correlation between sea temperature and sunlight in the Gulf of Maine.  In this phytoplankton instructional activity students use Excel to analyze data. 

How much does the sun heat up a lake or ocean? Scholars use a cup and a strong lamp to investigate the heat transfer and thermal layers in the ocean to come up with the answer. They collect data and graph it in order to better understand...

Turn your pupils into engineers who are able to use scientific principals to design a ship. This long-term project expects pupils to understand concepts of density, buoyancy, displacement, and metacenter, and apply them to constructing a...
