Product Details

Put an exclamation point on your year-end review of chemistry concepts with this electric, entertaining, patriotic set of five demonstrations!
• Passing electric current through a solution produces streaks of silver crystals that reverse course when the polarity is switched.
• Mix milk of magnesia with universal indicator and observe a colorful show when the antacid dissolves in simulated stomach acid.
• Take two rusty iron balls, wrap one in aluminum foil, then bang them together and observe the fireworks in this safe variation of the classic thermit reaction.
• Mix three sets of two colorless solutions and, in 30 seconds, the solutions flash red, white and blue in a tribute to the grand old flag.
• Add a pale solution to Uncle Sam’s topper, then hold on to your own hat as red, white and blue foam erupts from the stars and stripes–adorned stovepipe.

Concepts: Oxidation–reduction, electrolysis, pH indicators, acid–base neutralization, activation energy, exothermic reactions, buffers, solubility and equilibrium, clock reactions, catalyst, decomposition reactions.
Time Required: One full class period
Note: Common laboratory glassware and equipment are required but not provided.

Performance Expectations

MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
MS-PS2-5. Conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact
