Authentic Reading Ideas

• Molarity/Concentration

– Ions in drinking water, safety requirements, reports

– Concentration of pollutants in the ocean or salts in the ocean

– Blood work results, concentration of HDLs/LDLs, white blood cells, etc.

– Blood alcohol concentration

• Freezing Point Depression

– Amount of salt required to prevent roads from freezing at different temperatures

• Le Chatlier’s Principle/Altering Equilibrium

– Temperatures and pressures of industrial reactions

• Types of Chemical Reactions

– Stages in biological processes

– Industrial reactions

Learning Segment Experiment Ideas

• Molarity/Concentration

– Determining the molarity of Kool-Aid, then students get to drink it

• Solubility

– Making saturated solutions and observing effects of modifying temperature

– Dissolving rock candy

• Tying Concepts Together

– Give students an unknown salt, have them determine solutiblity/level of super

saturation at different temperatures, compare to solubility charts of known salts

to determine the identity

• Freezing Point Depression

– Adding salt to ice water to make ice cream

Learning Segment Experiment Ideas

• Physical/Chemical Changes

– CO2 bombs, dropping dry ice in soda bottles and putting the cap back on

• Reaction Rates

– Dissolve alka seltzer in water at different temperatures and time the reaction

• Types of Chemical Reactions

– Combustion in isopropanol

– Chemical reactions that evolve a gas and set off a rocket

– Reacting different metals with acids, observe evolution of gas

– Mixing solutions together to form precipitates

– Reacting pool chlorine with isopropyl alcohol
