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 explore many of the basic properties of matter including atoms, ions, elements, molecules, and density. The class explores an interactive flash-animated Web site to answer questions and clarify misconceptions they might have had...

Students define the following terms: predation, competition, carrying capacity and population. They can explain the patterns of growth and the limitations of growth. Students explain the difference between density-dependent and...

Learners view macroinvertebrates, or discuss previous collection activity. They graph data on macroinvertebrates in the Hudson River. Students discuss the relationship between habitat, environmental changes, and invertebrate diversity or...

Students explore the effects of aquatic trophic relationships on water transparency. They observe and explain the effects of reducing nutrient inputs on agal density on water transparency.

Second graders study force and what it does.  In this motion lesson students complete a demonstration on force and gravity and share their ideas. 

Tenth graders navigate and use the online Atlas of Canada. They explain the cause and effect relationship between human settlement and the natural environment and wildlife species. They utilize a worksheet imbedded in this plan.

Sixth graders explore ways to analyze the properties of water and examine the chemistry of water.  In this water lesson students work in groups and complete several activities. 

Learners investigate cartograms in order to explore the different countries on Earth. In this world geography lesson, students use the Internet to analyze data on different cartograms. Learners compare data, such as population density,...

Young scholars create their own balance to determine a difference in the weight (and composition) of cents made in different years.

Air, air, everywhere, but what's in it, and what makes Earth's air so unique and special? Journey through the layers above us to uncover our atmosphere's composition and how it works to make life possible below. Pupils conduct...

In this geography worksheet, students complete a crossword puzzle in reference to the geography of Europe. They identify the capital cities of various countries and the bodies of water which surround specific countries of Europe.

Pupils explore Earth's biosphere. In this biosphere instructional activity, students participate in group activities regarding biotic and abiotic factors, population density, and species' habitats.

Learners study the water cycle and how the sun is an important factor.  In this water cycle lesson students investigate how to desalinate water and explore the different densities of fresh versus saltwater.

Students develop critical thinking and awareness about the complexity of natural resource use, wealth distribution, population densities, poverty, and the environment. They think about people living in different parts of the world and...

Ninth graders explain the purpose of MPA's. In this biology instructional activity, 9th graders identify MPA's in Southern California. They simulate coastal sampling using candy from two buckets. Students analyze their results and share...

Students research the elements used to create fireworks. In this periodic table lesson, students discuss common metals, their characteristics, and their places on the periodic table. They work in small groups to research the elements...

Students visualize census data on a map and use a map key to read a population map. In this census lesson, students use a map of the Virgin Islands and corresponding worksheets to gain an understanding of population density.

Eighth graders investigate the different elements of the Periodic Table. In this chemistry lesson, 8th graders pick an element to research, then present to the class using a powerpoint presentation or a poster.

Students research to find information about populations and complete world maps by labeling the current population, and determining the 10 countries with the largest population. They search the "World Population Data Sheet." On the third...

Third graders research the history of cocoa. In this cocoa lesson, 3rd graders investigate how the cocoa bean has been traded from one country to another. Students create a timeline and map to track the history of the cocoa bean.

Students conduct a variety of experiments to explore gel electrophoresis. In this biology lesson plan, explain how this process separate DNA and RNA. They discuss the practical applications of this method.

Students investigate buoyancy, displacement and density.  In this flotation lesson students study the Archimedes' Principle, analyze data and draw conclusions. 

Young scholars identify and complete activities about the structure of the Earth. In this Earth structure lesson, students view a Powerpoint about the Earth's layers and complete a diagram. young scholars compare temperatures in the...
