Middle School Chemistry: Lesson Plans: Forming a Precipitate

Lesson plan in which learners design an experiment to determine if different types of liquids affect the amount of dissolution of an M&M candy shell.

Lesson plan with mulitmedia links in which students identify and control variables to help design a solubility test for different liquids in water.

Students use their own model of a salt crystal and water molecule to show how water dissolves salt. Then, they relate their observations to the structure of salt, water, and alcohol on the molecular level.

Students first observe a solubility test between salt and sugar. Next, they design their own solubility test with four known crystals and an unknown to discover the identity of the unknown.

Students observe and investigate why water has a strong surface tension.

An activity through which students learn why gas is able to dissolve in water, and how heat affects the solubility of a gas in a liquid.

Students observe reactions of liquids with different known powders in this lesson. Unknown powders are then identified using characteristic chemical changes.Site includes a procedure, teacher instructions, and video instruction.

After observing a demonstration of a chemical reaction between a burning candle and the oxygen in the air, young scholars use atom model cut-outs to model the reaction and see that all the atoms in the reactants show up in the products.

Young scholars observe and describe, on the molecular level, how heating and cooling affect the motion of molecules in a solid.
