Demonstrate how ice floats on water and get the class thinking about why icebergs are so deceiving. Investigators then experiment with mixing water of the same temperature and water of different temperatures. Make sure to explain the...

Scholars find Earth won't support humans much longer and need to identify a planet with water to inhabit. They test four unknown samples and determine which is the closest to water. Then they explain and defend their results.

A micro-unit on the phase changes of water includes three laboratory activities. Junior scientists compare the densities of ice and water, and then they do the same for cold and warm water. They examine freezing and boiling temperatures....

Investigate how temperature affects the density of water and stratification that occurs in bodies of water when temperatures vary. Water of differing temperatures is given different colors to see the layers that form. The lesson is meant...

Students set up working models demonstrating lake turnover and the formation of deep water masses in the oceans.

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

Young scholars conduct a series of investigations on the unique properties of water. In this general science instructional activity, students explain what causes water's surface tension. They explain the different stages in the water cycle.

Students discover the different forms of water on Earth. In this states of water lesson, students read material on the different forms of water and how they are created. The students answer written questions on worksheets.

The arctic seas contain currents that are both warm (with high salinity) and cold (relatively fresh water) that circulate throughout the year. Through discussion, a lab, and a web quest, participants explore the impacts of melting and...

Students use video, Internet research, graphs and tables, worksheets and hands-on experiments to investigate the properties of water in a lake environment. They work under direction or through an inquiry process.

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...

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.

How can you relate colligative properties of solutions to everyday situations? Pupils first discuss the concepts of density, boiling and freezing points, then demonstrate how to accurately determine the boiling and freezing point of...

Students 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 and...

Young scholars examine how circulation currents of the ocean. They use a tub of hot and cold water to demonstrate the currents. They discover how salinity and temperature of water affect its movement.

First graders observe water changing states from a solid to a liquid to a gas. They predict what they think happen to ice cubes as they sit out. They paint water with paintbrushes outside the classroom in the sun and watch the water...

Students explain how melting glaciers affect global warming. In this earth science lesson plan, students investigate the change in ice density as it melts. They discuss the human and environmental impact of rising sea levels.

Students observe the freezing times and temperatures of water with varying levels of salinity. They determine how icebergs form, how they act, and what they may be made of. They discover that salinity level affects the time it takes...

Although this is a science lesson, it can be adapted to help meet Common Core standards in math as well. Starting scientists describe physical properties of objects and explore three forms of water. To address the Common Core, they can...

Students discover the origin of the Great Ocean Conveyor. They participate in a demonstration showing how salinity and temperature affect water density. They also examine the new sea ice that forms every winter.

Students investigate the properties of solids, liquids and gases. For this states of matter lesson plan, students observe dry ice and its characteristics. They calculate the density of dry ice and observe the sublimation of the dry ice...

Learners conduct an experiment that shows them how salt water allows things to float. In this salt water lesson plan, students mix ingredients together to create salt water and observe how it makes the oceans dense. They then interpret...

Students identify the contents of a glacier like those found in Patagonia. They construct a mini glacier model in class. Students compare and contrast the classroom model with Patagonian glaciers. They label specific parts of the...

Young scholars observe a demonstration on the role of thermal conductivity in heat transfer.  In this thermal conductivity lesson, students design and conduct an experiment to compare the thermal conductivity of four substances....
