Teacher Resources for Instructional Planning


HS, Physical Science Std 2: Identify solutions in terms of components, solubility, concentration, and conductivity. • Comparing saturated, unsaturated, and supersaturated solutions • Comparing characteristics of electrolytes and non-electrolytes • Describing factors that affect solubility and rate of solution, including nature of solute and solvent, temperature, agitation, surface area, and pressure on gases.

Lesson Plans: Solubility of a Salt To measure the solubility of KNO3 at various temperatures and to construct a solubility curve. Rate of Solubility Discover factors affecting the rate of solution. Solubility To make a saturated solution using solvents at different temperatures. Surface Area and Reaction Rate This is an oldie but goodie for demonstrating how increased surface area leads to increased rate of reactions. A Reaction Between Gases This is a spectacular demonstration which can challenge students in diverse ways: to describe the visible features of the reaction, to interpret observations in terms of reacting volumes of gases, and of equilibrium between gases. Solubility of Lead (II) Iodide To determine the solubility product constant, Ksp, for PbI2. Concentration vs Solubility The student will be able to distinguish between concentration and solubility. Solubility Curves To show how the solubility of a salt such as ammonium chloride varies with the temperature and how to plot its solubility curve on the basis of observed data. Lemon Voltage We will try to make a needle move on a voltmeter using two different metal strips and a lemon as the electrolyte source. Electrochemistry Students understand that electricity causes chemical reactions and chemical reactions can cause electricity. Electrolysis of Aqueous Potassium Iodide In this experiment you will electrolyze an aqueous solution of potassium iodide and then identify the products that are formed at the electrodes. Electrolysis The observe the effects of different electrodes on the electrolysis of a substance. Electroplating How does the operation of an electrolytic cell create to potential to electroplate out Cu, zinc , or silver.
