Young scholars work together to observe the bond lengths of single, double and triple bonds. They make their own predictions about the strength of the bonds and chemical reactions. They answer discussion questions to complete the lesson.

Students observe how substances are held together by bonds. In this physics lesson, students demonstrate how a substance is held together by ripping newspapers and stretching marshmallows. Students complete a data sheet.

Hate to vacuum, but enjoy using a vacuum pump? Explore a lesson that starts with a demonstration of boiling water at various temperatures by using a vacuum pump. Then scholars design their own experiments to measure vapor pressure and...

Students read about Humane Genome Project, examine structure and function of DNA, and participate in gel-electrophoresis lab. They complete Internet activity to test their knowledge of DNA.

Students investigate the carbon dioxide content of different sodas. In this chemistry instructional activity, students explain why PET containers are preferable than HDPE for soda bottles. They collect data and graph them.

Young scholars conduct a series of experiments to explore carbon dioxide properties. In this chemistry lesson, students explain the production and uses of this gas. They measure its amount in soda and waste product of yeast.

Ninth graders generate and analyze data to determine which and how much of two polymers best absorb oils, formulate procedure to accurately determine how many times its own weight particular polymer can absorb, and develop understanding...

Students relate chemistry to an object they use everyday. They research information related to chemistry and create their own webpage. They are to keep their page up to date as new observations are taken.

Students articulate an explanation of photosynthesis. They identify problems they have with comprehension of how a plant gains mass. Students describe a historical experiment.
