Students will synthesize magnesium hydroxide and aluminum hydroxide using common household products. This lesson plan is a tool to use when teaching chemical reactions. The lessons contained in this unit may be used together as a unit or as stand-alone lessons. In Lesson Three, Flavor-"Fool", students discover how the five senses affect the perception of flavor. In Lesson Two, Making Scents of Esters, students prepare esters through the process of esterification. Lesson One, What is Flavor.and How do We Know?, introduces students to the components of flavor, taste and aroma, through interactive experiences. The unit presents basic concepts of organic chemistry such as defining organic compounds, functional groups, naming organic compounds, and the importance of organic molecules in everyday life. This three-part unit introduces students to organic chemistry through the study of flavor. Emphasizing the role of valence electrons in the outer shell will highlight important biological elements and their reactions with other elements. This lesson is used to teach basic chemistry concepts. The worksheet is completed from information gathered on a specific internet site, The intention is to take a class to the library and allow students to each fill out their own worksheet on a different element. The lesson was developed for a Physical Science class. This is a worksheet that addresses properties of atoms and the periodic table. Students will select a category of their choice (animals, food, etc.) and come up with a periodic table of these 'elements' organized in a way of their choosing. This group project is meant to reinforce the concept of that the periodic table is a method of organizing the elements. Using the freezing-point depression and the molality of the solution, the molecular weight of the solute is determined. The freezing-point depression of the solvent is determined from the data. Technology is used to collect, graph and analyze both the cooling of a pure solvent and the cooling of the solvent when a solute is added. Using Freezing-Point Depression to Find Molecular Weightįreezing-point depression, a colligative property, is investigated.This lab can be remediated or extended by including more identifications of less obvious classification. This inquiry based lab builds upon the ability to classify matter and asks the student to explain the experiments used to determine the chemical and physical properties of the sample, and determine if their data matches their classification. Several types of household matter will be placed at different lab stations and students will be asked to identify if it is a solution, mixture, compound or element, and what type, if applicable. This laboratory teaches students about water hardness, polar and non-polar molecules, and anions and cations.
