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...

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 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.

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. For 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, 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 instructional activity students study the Archimedes' Principle, analyze data and draw conclusions. 

Students 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. students compare temperatures in the Earth's layers...

Pupils study plate tectonics.  In this plate tectonics lesson students build a cutaway scale model of the Earth. 

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.

Students use real satellite data to determine the changes in near-surface air temperature at different times of the year over the Caribbean Sea. They discover how Earth's tilt causes seasonal differences in incoming solar energy. They...

Students examine what lies within the Earth. They research and create scale models illustrating the layers of the Earth and write skits advocating a travel plan to send a probe into the Earth's mantle.

High schoolers examine hurricanes. In this web-based meteorology lesson, students study the relationship between ocean temperature and hurricane intensity. They differentiate between intensity and frequency of hurricanes.

Third graders experiment with coins and water to explore light rays.  In this light and water lesson, 3rd graders work in pairs to observe what happens with a coin in water or how it appears based on the density of the water....

Students discuss the difference between major landforms as a class. In groups, they rate the landforms based on the needs of the community that wish to settle there. They also discuss the push and pull factors of the colonists that made...

Students investigate the states of matter. In this physics lesson, students use water and ice to demonstrate the characteristics of a solid and liquid. Students record their observations as the state of the water changes.

Students use physics to discuss diversity. In this social interaction lesson, students use their knowledge of colors and filters to relate it to stereotyping and prejudices.

Learners compare and contrast the characteristics of the three different types of black holes. In this space science lesson, students research black hole's lifetime, location and evidence of existence. They present their findings to class.

Students relate to the idea of periodicity & give example of other periodic events and identify and use the periodic table as a useful resource. They also identify the relationship of elements to certain groups & periods &...

Learners work in teams of 2 to complete the presentation portion of the assignment. They may be required to work alone or may work with their partner to complete the "Board Member's Responses."

High schoolers explore the basic building blocks of our planet.  In this minerals lesson students begin the process of forensics on the basis of investigation and drawing conclusions from observations.
