The Synthesis of Some Organic Compounds And Their Representative Structures
Young scholars examine how to represent organic compounds three-dimensionally. They write a synthesis reaction for three demonstrations, and construct a three-dimensional structure using a molecular modeling set.
Curated OER
Silly Semi-Solids
Students create a polymer out of glue, water, and borax. They discuss the resulting substance and perform several experiments with it.
Curated OER
Pauli's Magical Water
Students predict the shape of molecules using VSEPR theory. In this chemistry lesson, students differentiate a polar and nonpolar molecule. They discuss why water's polarity is very important.
Curated OER
The Nature Of Dissolving Processes
Students examine the rule of "like dissolves like." They define and describe solutions and solubility models on molecular liquids, ionic solids, and molecular solids.
Curated OER
Diffusion Across a Selectively Permeable Membrane
Students investigate how water passes through cell membranes. In this biology lesson, students differentiate osmosis and diffusion. They illustrate the movement of water in both processes.
Curated OER
Slime and Intermolecular Attractions
Students explore the strength of intermolecular attractions. They make slime and compare the difference in the physical properties of sheet and powdered polyvinyl alcohol with polyvinyl acetate.
Curated OER
Tie Dye
Students practice writing research proposals to test the color fastness of a dye once it has been exposed to a t-shirt. Each proposal needs details of experimental design, length of treatment, and means of cleaning the shirt. All...
