There's a lot content packed into the four lessons of this physical science unit on density. From salad dressing to the water cycle and hot air balloons, these lessons engage students in hands-on activities that explore real-world...

This particular lesson was written by the National Earth Science Teachers Association, but density is a concept that you can teach at the beginning of the school year in your life, physical, or earth science classes. It would be fun to...

Density comes to life as investigators place soda cans into containers of various liquids to find if they sink or float. They layer different density liquids, compare densities of different gases, and more. A total of six different...

Given a variety of rocks, junior geologists calculate densities and correlate them to Earth's layers. As a simulation of continental crust, they experiment with how materials of differing density float in water. Finally, they...

Science learners simulate what happens when ice breaks up and floats on water and how increased pressure on ice causes it to melt faster. They view a clip from the movie, The Day After Tomorrow, and relate their lab activities to what...

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

Students relate the concept of density in relation to the rocks that make up the Earth. They determine the density of various rock specimens and answer assessment questions.

Eighth graders examine the physical properties of different minerals. In this earth science lesson, 8th graders explain the uses of minerals in their daily lives. They complete the mineral identification table during the lesson.

Ice is nice, and its condition on the planet has a significant effect. Junior geoscientists experiment with ice melting in both water and on land to discover how each affect the rising sea level. This detailed lesson outline even...

Students role play as paleontologists who make inferences about the weight of dinosaurs. They use models and the density of water to make these inferences.

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

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 explain how wetlands minimize the impact of hurricanes. In this earth science lesson, students investigate how different materials affect the steam plume path. They complete their worksheet after the lab.

Pupils study the ocean and its characteristics.  In this oceans lesson students complete a lab activity and are able to predict temperature of certain depths. 

Students are introduced to the forces that are responsible for generating waves in the ocean and how these forcesf differ from those that cause currents. They are able to explain how water molecules in a wave do not move in the direction...

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.

Learners use water, beakers, hot plates, paper dots, and goggles to participate in a hands on activity where they see how a convection current creates wind. In this convection current lesson plan, students participate in a hands on...

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.

Learners examine population growth and how it impacts our environment.  In this population lesson plan students identify the causes and consequences of overpopulation.

Students collect chemical, physical, and biological data from a local lake throughout the year. In addition, students discuss the design of an experimental structure for water collection at several specific depths as well as assess the...
