Young scholars are introduced to the topic of light interference through this hands-on activity. They observe how light reflects off two surfaces and then meets to form an interesting variation of color on a film surface.

In this science worksheet, students use the key code on the right to unscramble each of the scientists. They also match each of the scientists found to their correct description.

Students investigate the different bioluminescent organisms. They use microscopes in order to make observations and draw what is seen. Students demonstrate they have studies the differences between the process of photosynthesis and...

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

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 study La Chatelier's principle and identify how carbon dioxide may affect pH.  In this coral instructional activity students complete a worksheet on pH and observe a lab.

Students use baking soda, vinegar, matches, and other materials to pour gas. In this air lesson plan, students use the materials to pour gas and learn that air can be a fluid like a liquid.

Students examine how hurricanes grow and their strength levels through an interactive program. They define terms associated with hurricanes and how the public is affected by the storms.

Students participate in a role-playing activity that demonstrates how whales use sound as an adaptation to their environment.

Students discover how light reflects off surfaces. In this hands-on demonstration, students examine how variations in color are produced by light interference.

Use this site as a resource to learn about the many aspects of water.

Of course it can, you say: ice is water and ice floats. And you're right. But we're talking about water in the liquid phase Can liquid water float on water? The goal of this project is to investigate what happens to layers of water with...

A student inquiry into properties of the ocean's carbonate buffer system, and how changes in atmospheric carbon dioxide levels may affect ocean pH and biological organisms that depend on calcification.

Describes the properties of seawater and the variations depending on its location, e.g., near a shoreline, in an estuary, or as sea ice. Discusses the instruments scientists use to measure the density of water and explains other...

Good starting point for researching ocean life. Find general information, research-topic ideas, a glossary of important terms and people, and numerous links to related sites.

Students investigate the properties of water in the ice and liquid phase as it relates to convection in the ocean and density driven circulation, and ultimately the climate.

Students simulate ocean water characteristics in order to recognize that the effects of salinity and temperature are the drivers of thermohaline circulation.

For this lesson plan, students will trace the flow of water in the environment, investigate simulated effects of global temperature change on oceanic levels, evaluate changes within the water cycle, and explain several different...

Seven hands-on lessons module in which students explore oceans. Inquiry-based investigations include properties of seawater, ocean water and currents, and features of the ocean floor.

Realize that there is more in ocean water than just salt. Find out about the salinity of water and how changes in salinity may affect organisms living in the water.

[Free Registration/Login Required] This flipchart is an introductory lesson to a fifth grade unit on oceans. The flipchart contains information about the oceans and properties of ocean water.

A detailed overview of the Earth's atmosphere, with explanations about atmospheric properties, the structure of the atmosphere, its four layers, atmospheric processes, energy heat transfer, conduction and convection, and radiation. All...

Engage students in the study of the ocean and saltwater with these activities. Students will see that saltwater has different physical properties than freshwater - mainly density. This lesson can serve as a springboard into other...
