Properties of Lipids—Laboratory Kit
By: The Flinn Staff
Fats and oils, waxes and cholesterol, steroid hormones and Vitamins A and D—all of these natural products belong to a diverse class of biologi- cal compounds called lipids. What are the properties of lipids? What role do lipids play in the chemistry of life? By performing three specific tests, students identify and classify lipids and examine their properties.
Complete for 24 students working in pairs.
Making Soap—Laboratory Kit
By: The Flinn Staff
Soap-making is an ancient craft and one of the oldest known chemical reactions involving organic compounds. Soaps are sodium and potas- sium salts of fatty acids. They are prepared by reacting fats and oils with a strong base, such as sodium hydroxide or potassium hydroxide. In this experiment, students make soap and study its properties. The soap will be prepared via saponification of a fat and oil with a solution of sodium hydroxide. The properties of the soap will then be investigated—its pH, texture, emulsifying action, and solubility in hard water.

Preparation and Properties of Biodiesel—
Laboratory Kit
By: The Flinn Staff
Biodiesel is an alternative processed fuel obtained from biological sources, usually vegetable oils, for use in cars and trucks. Alternative fuels such as biodiesel or bioethanol generate a great deal of interest because of concerns about climate change and the depletion of nonre- newable energy sources such as petroleum. In this activity students prepare biodiesel and investigate the amount of energy it releases when burned. Cooking (vegetable) oil is reacted to form a methyl ester by transesterification with methyl alcohol and a strong base. Once produced, the heat of combustion of the resulting biodiesel is deter- mined by calorimetry.

Build a Solar Cell—Laboratory Kit
By: The Flinn Staff
Solar energy, the conversion of sunlight to electricity, has enormous potential as a clean source of renewable energy. High-performance solar cells are very expensive while less expensive solar cells are not as efficient. Dye sensitized solar cells mimic the process that occurs in photosynthesis to harvest sunlight and convert it to electricity. In this activity, students build a dye-sensitized solar cell (DSC) and learn about the principles behind its operation.
Complete for 24 students working in groups of four.
