Blinking Holiday Colors—Chemical
Silver Holiday Ornaments—Student Laboratory Kit
Create stunning silver ornaments in a practical application of a classic redox reaction. Mix dextrose with a basic silver-ammonia solution in a glass ornament ball, swirl, and a lustrous silver mirror plates out inside the ornament. Students perform analyses using atomic mass, radius and density calculations. Includes 24 glass ornament, solutions, Beral- type pipets, reproducible student handouts and complete Teacher Notes. Complete for 24 students working individually.

Ornament-Making—Student Laboratory Kit
Combine chemistry and art to design a holiday ornament! Ideal for the day before a holiday break, this laboratory kit reinforces redox concepts. Students start with a simple piece of galvanized iron and transform it with redox reactions into their own work of art. Includes reproducible student instructions, teacher tips and all materials needed to perform the lab. Complete for 28 students working individually.

Demonstration Kit
Stir two solutions with a unique mixture of indicators into separate beakers and watch as the solutions swap colors from holiday red to green back again! At low pH, one mixture is red, the other green. At high pH, the red indicator turns green, and green switches to red. The key is a clock reaction. Each solution starts out slightly acidic and buff- ered,butasreactantisconsumed,thepHrapidlyincreasesandthe holiday colors rapidly reverse.

Santa in a Snowstorm—A Winter Holiday Chemical
Demonstration Kit
24
Here comes Santa Claus, here comes Santa Claus... right into your classroom! Capture the attention of your class with a fun holiday seasonal demonstration. Explore solubility and saturation with this easy-to-prepare demonstration. Simply place excess benzoic acid in a heated solvent until a solution forms. As the solution cools, excess benzoic acid precipitates out in a “snow-like” form. It’s a winter wonderlandinabottle!
