What's a better way to start the new school year than with some new experiments? Learn how to use a variety of color changing experiments to teach students about the Diet Coke and Mentos experiment, acids, bases, chemical and physical changes, and climate change.
You may have observed a red to blue color change when you rinse your bowl after eating frozen blueberries. Sounds like an acid-base reaction, doesn’t it? Well, read on to learn about the blueberry surprise!
The Devil's Milkshake is a simple, yet interesting chemistry experiment that fits well as a Halloween demo.
Watch this video and see if you can figure out how red, white, and blue colors can all be made from the same chemical solution!
The author explains how she assigns roles for her students while completing laboratory work. The lab activity is designed to allow students to explore the use of indicators. It serves as an introduction to acids, bases and pH.
Did you figure out how the experiment in Chemical Mystery #14 was performed? The solution is presented here!
You can figure out how this Valentine's Day experiment was done...if you know your chemistry, that is!
The unit of acids and bases is difficult for most students in Advanced Placement Chemistry. The variety of various calculations can be overwhelming. The Acid Base Speed Dating Activity engages students in completing a series of problems. Each student is assigned a specific solution and then determines their individual pH to complete their personal “Solution Biography.” Then the speed dating begins! For each date, the students need to find a specific match and determine their combined pH value.
Students will be engaged in this activity that will help them make the connection between food and chemistry. Acid, bases and pH are addressed.
The chemistry of the Sunflower dye found in McCormick’s Color from Nature food dyes is explored in this post. This is the last in a three-part series in which several experiments and demonstrations that can be done with Color from Nature food dyes are described.
