Product Details

It’s spring break. Time to cast off the winter doldrums and embrace the bright new season! Celebrate the arrival of spring with six fun demonstrations:
• An oscillating chemical reaction alternates between frigid blue and sunny yellow, just like the unpredictable spring weather.
• A rainbow suddenly appears, then just as quickly disappears, when alternating colorless solutions are mixed.
• Shake a yellow solution and the color changes from yellow to red to spring green, the color of new plant growth and one of the prettiest colors of the year.
• Spray a special misting solution on paper flowers and watch them bloom—April showers bring beautiful May flowers!
• A blue flower changes to pink as the weather changes and the humidity rises.
• As spring break approaches, all thoughts turn to... VACATION! Sit back and enjoy a chemical “sunset” on your favorite tropical beach.

Concepts: Oxidation–reduction, acid–base reactions, pH indicators, oscillating reactions, reaction mechanisms, LeChâtelier’s principle, Tyndall effect, colloids.
Time Required: One full class period
Note: Some common laboratory equipment is required but not provided.

Performance Expectations

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.
HS-PS1-4: Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.
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.
MS-PS1-5: Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.
