Newcomers to chemistry compare hydrogen peroxide to water, realizing that the difference of one oxygen atom significantly affects the chemical properties. Other pairs of compounds and their formulas are also examined. A few chemical...

Biotechnology pros produce their own biofuel using waste oil and fresh vegetable oil. They test the quality of their product using titration techniques and pH analysis. They write their observations and report their findings. Be aware...

Future chemists practice laboratory techniques by creating a monochloramine solution. The objectives are to use of dilution, 9concentration, and measurement skills and to prepare a solution that will be used in a water treatment...

Eighth graders investigate chemical reactions to produce polymers. In this polymers lesson plan, 8th graders experiment with sodium silicate and ethyl alcohol to make a polymer. They also experiment with borax and glue to make a polymer....

Students are given the unique opportunity to see the contrast between parts of a leaf that have photosynthesized and parts of the leaf that have not. This visual image helps students see the results of this biological process. At the...

Students explore how temperature effects the processes of evaporation and condensation and how the air may be polluted  by the evaporation of certain compounds.  In this temperature lesson students complete a lab and a worksheet.

Young scholars investigate how to denature proteins. In this denaturing protein lesson plan, students explore the different ways to denature proteins in the lab. They use heat, acids and bases, organic compounds and heavy metals to...

Scratch and sniff an introduction to organic chemical reactions. A creative lesson has individuals study the esters commonly used in scratch-and-sniff stickers and advertisements. Following the lab procedure, scholars create the organic...

Students design and conduct an experiment to investigate what happens when salt and ice come together and to determine if one form of salt is better for melting ice on steps and sidewalks.

Learners initially engage in online research and consult print materials to identify a compound to produce. Once a selection has been made, individually, students conduct lab experiments to isolate substances. The end product is a...

Middle schoolers define vocabulary related to the parts of the atom.  In this matter lesson, students navigate the web to find the structure and the forces that affect atoms.  Middle schoolers complete an experiment with...

Students explore chemical cahnges and the effect of temperature on chemical mixturees, They make observations of the behavior and appearance of certain chemical mixtures and reactions.

Students conduct a variety of experiments to explore protein. In this biology lesson, students solve a mystery by testing for the presence of glucose, protein starch and triglycerides. They explain how DNA transcription and translation...

Young scholars explore the properties of enzymes. In this chemical reaction lesson plan, students explore enzymes through a Web-quest and investigative study. Young scholars will collect and summarize data and create a class...

Pupils pretend they are a food-quality tester. They develop a kit to test food for sugars, starches, proteins and lipids. They answer questions to complete the lesson.

High schoolers discuss the importance of plankton in the ocean ecosystem. In this biology lesson, students identify the different types plankton by observing them under the microscope. They explain how plankton population affect global...

Students differentiate between high and low viscosity. Students collect, graph, and interpret data, then quantitatively measure polymer solids. Students experiment with a household example of an emulsion polymer.

Students explore oxygen and its physical and chemical propeties.  In this investigative lesson students complete several experiments using oxygen.

Fourth graders improve their understanding of Graham's Law by using properties of gases to evaluate the rate of effusion of two compounds as they vaporize. They engage in a lab which elevates their understanding of the properties of gases.

Students discuss what the m in E=mc2 represent. They relate that mass in a chemical reaction is always conserved. Students convey that atoms rearrange themselves in chemical reactions to form different molecules and compounds.

Students conduct research to determine the structural formula for Allicin, a component of garlic. They participate in a lab to extract Allicin from garlic and complete a set of questions about their work.
