Students study classification systems by sorting Legos and determining how the different pieces are classified. They list as many attributes as possible to use for sorting.

Learners design and conduct investigations that illustrate the effect bioremediation has on organic matter and determine environmental applications. They, in groups, present their findings to the class.

Students demonstrate that material strength varies with shape and arrangement.

Eighth graders examine avalanches after reading excerpts from John Muir's book, "The Yosemite." In small groups, they conduct experiments with flour, sugar, and potato flakes representing different snow consistencies. Then, 8th graders...

Students create spectral colors. In this hands-on science lesson, students examine the electromagnetic spectrum as they follow steps to create a model that separates and displays light.

Students explore human growth and development as they participate in class activities, reading and discussion. Worksheet and handouts are included in the lesson.

Students conduct toboggan time trials to investigate the variables that have the greatest effect on toboggan speed. In small groups, they develop a hypothesis to test and perform three trials on the toboggan run for each variable.

Third graders consider outer space. In this introductory solar system lesson, 3rd graders complete a KWL chart and listen to the story The Magic School Bus: Lost in the Solar System, by Joanna Cole & Bruce Degen. They will contribute...

Students examine a potential asteroid impact site. They describe evidence and theories for extinction events.

High schoolers research the Internet to fill out their scavenger hunt sheet.  In this research lesson students search the Internet for answers to the questions on the scavenger hunt worksheet. 

Students discuss how simple machines have made our lives easier and construct a compound machine. In this machines lesson plan, students watch a video on machines, look at websites, and follow task cards in order to make a simple machine.

Fourth graders, in pairs, explore energy transfer and species interrelationships by viewing slides on a microscope. hey explore phytoplankton (producers) and zooplankton (consumers)

Students examine the role photosynthesis plays in plant survival.  In this renewable energy instructional activity students document their observations and analyze and interpret their results. 

Students, after reading the explanation given below, use FoilSim to gather and record data on temperature and altitude generated by the FoilSim control panel.
