Is it necessary for biology faculty colleagues to spend a month or so covering foundational chemistry in general biology courses then for the remainder of the semester require students to only know a small fraction of chemistry covered? This post briefly looks at what chemistry is needed for general biology.
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!
Learn a simple way to relate the heat equation (Q = mc∆T ) to climate change.
Spectroscopy-based experiments are commonplace in college labs. This out-of-classroom activity post provides links to applications of spectroscopy in a diverse spectrum of disciplines and work fields.
Come explore the “Fire and Ice” pedagogic field laboratory. Follow suggested pathways and perspectives, or blaze your own trails. Visit for 10 minutes or for hours.
The author explains a virtual chemistry lab activity for use in a high school chemistry class. This activity is an excellent way to introduce measurements, significant figures, and the concept of density.
Determining the empirical formulas of ionic compounds based on charge balance is often a challenge for beginning chemistry students. Many visual aides have been developed for this purpose, from repurposing commercial interlocking bricks to custom 3-D printed bricks. This article describes yet another option– upcycled can carriers.
The use of anthocyanins in red cabbage extracts as pH indicators has long been a popular classroom activity. Flowers, fruits and vegetables contain a diverse range of anthocyanins. This investigation explores further applications of plant-derived dyes including reversible reactions based on oxidation/reduction chemistry and other reactions to illustrate colour changes that are not solely dependent on pH change. By using household materials and plant dyes, this investigation may potentially be completed at home if necessary.
