Teaching and learning the concept of limiting reactants can be challenging. In this activity students manipulate beads to learn about stoichiometry. A virtual drag & drop version is also available.
Heartburn is a very common ailment. Many people rely on antacids such as Tums®, Rolaids®, or Milk of Magnesia to settle their stomachs, but have you ever wondered how those antacids work?
"Who Poisoned Veronica Merriweather?" is a fun application of formula stoichiometry for students who are placed in the role of a CSI lab sleuth helping to interpret chemical data to identify a murderer. Topics covered include formula stoichiometry, percentage composition, empirical and molecular formulas and gas chromatography–mass spectrometry.
A variety of resources are available for chemistry faculty interested in incorporating lessons and activities around art and archeology. Find out what they are in this follow up post from the inaugural ChemEd X virtual Journal Club held April 2022.
Here is a great way to use spreadsheets to both collect student data and provide instant feedback during labs with quantitative data.
Nora Walsh shares the outline of the interactive notebook pages she uses for her gases unit. Templates for all of the documents and foldables are available for download.
Nora Walsh has been using interactive notebooks for some time. Here she outlines her stoichiometry unit and explains how she uses the interactive notebooks with her students.
Engage your students with this stoichiometry scavenger hunt!
The unspoken word of chemistry: Non-stoichiometric. Stoichiometry and non-stoichiometry are concepts that combine to make a solution that does not have to be difficult to understand.
The lab activity shared here is a simple experiment where students use stoichiometric principles to experimentally determine the amount of sodium bicarbonate in an Alka-Seltzer tablet. Novice students tend to find stoichiometric calculations difficult, so practicing the calculations on a pre-lab assignment boosts their confidence and ultimately leads to more successful labs. The Asynchronous Video Pre-Lab Assignment shared here demonstrates the procedure and the calculations required in the experiment.
