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...

In 1977, scientists discovered hot springs in the middle of deep, cold ocean waters near the Galapagos Islands. Scholars research the chemical reactions that explain what scientists found at the Lost City. A discussion connects many...

Students participate in a group lab in which they complete the process of bacterial transformation. If lab procedures are followed correctly, Students see their results in a few days...bacteria glowing green.

If you are looking for a great way to present natural selection in humans, look no further. This handout is intended to accompany the 14-minute video The Making of the Fittest: Natural Selection in Humans, which can be found on the...

Students participate in an extended laboratory research to experience how scientific information is obtained, upon which we build scientific knowledge and understanding.

Assign groups of middle school oceanographers to research one of the following underwater robots; ABE, Herculues, ROPOS, RCV-150, Tiburon, or general purpose ROVs. An included handout guides them through information to be gathered. Each...

If you are looking for a great way to present natural selection in humans, look no further. This handout is intended to accompany the 14-minute video The Making of the Fittest: Natural Selection in Humans, which can be found on the...

Seventh graders are introduced to Earth day--- what is it and why do we care, ease into topic of pollution, where have they seen pollution in their community, steer conversation in the direction of the Anacostia. They are reintroduced...

Who actually goes looking for a virus? Expose your class to the high-stakes life of an epidemiologist on the trail of the Nipah virus. Pupils engage in a short video, then examine how scientists predict, model, and find the source of...

Students investigate the applications of DNA fingerprinting, They read crime scenarios and using the details of the crime and laboratory experimentation decide the suspects guilt or innocence.

Students name objects that are the same size, shape, and weight as the human brain. They touch the model brain, feeling the folds, etc. They make connections to the chart displaying the brain-like objects. They touch the 'potato flake'...

As individuals or in small groups, marine biologists research and discuss archaea and their unusual behavior as compared to bacteria. Teach them about the chemical makeup of the cell membrane of these strange organisms. This complex...

Meant to be a simulation of a deep-sea exploration, this requires that another lesson be completed first. In that lesson, titled "Animals of the Lost City," marine biology buffs construct murals of benthic communities. In this lesson,...

Students engage in a variety of activities designed to facilitate the understanding of DNA. Activities include preparing human chromosome spreads, separating a mixture of dyes using gel electrophoresis and extracting DNA from onion cells,

Students examine the structure, function, and characteristics of microscopic organisms that inhabit freshwater through collection of water samples and observation through microscopes.

Students compare and contrast classification systems used throughout the world. They also examine the importance of preserving biological diversity.

Students become familiar with common microorganisms and experience exploring the microbial world.

Students explore principles governing diffusion and osmosis. Students perform a dialysis tubing experiment. They obtain core samples of potato in varying concentrations of sugar-water to measure water potential of the potato cells....

Students research the theory of evolution and the controversy.  In this evolution lesson students view a film on Charles Darwin then they write an essay about whether or not intelligent design should be taught in science class. 

Students identify animals observed by Lewis and Clark while evaluating the animal's habitat and describing the animal's behavior. Students construct a food web mobile to illustrate the animal's position in the food web in the 19th...

Fifth graders brainstorm a list of ways the Earth's surface can change. As a class, they are introduced to the concepts of erosion and weathering and discover how wind and water cause changes to the surface of the Earth. To end the...

Learners practice their researching techniques by preparing a presentation with little notice.  In this information research lesson, students utilize the Internet to research one of several subtopics concerning panthers....
