Can Alkaline Water Change the pH of your body? We use chemistry to put this claim to the test!
Science Practice: Using Mathematics and Computational Thinking
Did you know that sand can be converted into a mixture of gases that spontaneously ignites in air? The procedures involved are relatively simple to perform, spectacular to observe, and relate to a rich assortment of chemical principles.
Natural food dyes are being sold online and in stores that can be used as acid-base indicators. These dyes open up a host of possibilities for at-home and in-class. For example, these food dyes can be used as indicators in the quantitative titration of the Mg(OH)2 in milk of magnesia.
Michael Jansen reflects on a very common empirical formula lab that asks students to determine the empirical formula of MgxOy. He then explains how he continues to use it as a "successful failure", how he demonstrates an alternate procedure and leads his students to an important lesson.
The Golden Drain is a case study developed by Sharma and Wolfgang where students work to uncover a company’s lost revenue due to the error of a new employee.
A lab practical with an escape room story turned out to be a great final exam.
In this virtual activity, a video introduces stoichiometry and guides students to think conceptually using a simple baking analogy. Afterward, stoichiometry calculations connect to the analogy, that are then reinforced with a simple experiment. Finally, students explore a PhET simulation to deepen their knowledge.
What is the pressure inside a bottle of soda pop? Read this short article to find the surprising answer to this question, and also to learn how to do an experiment to answer this question for yourself!
Learn how to thermochemically analyze the Devil's Milkshake chemical demonstration - just in time for Halloween!
This activity allows students to see many different types of scales in order to become proficient at measuring and determining how many digits to record in any measurement, whether it be volumes, masses, lengths, etc.
