This demonstration lays the foundation for what science is all about: proper experiments, properly carried out, properly interpreted.
The theme to the 2022 National Chemistry Week, observed October 16-22, is “Fabulous Fibers: The Chemistry of Fabrics”. A visit to Natural Fiber Welding, Inc. in Peoria, IL, revealed how that company is using ionic liquids to solvent weld cellulose fibers together to produce more durable yarn which can then be made into more durable fabric. The production method and “greenness” of the product is discussed, from the cellulose itself to the recycling of the solution used in the welding process. Macroscopic demonstrations of the fiber solvent welding process are also described.
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?
The use of multiple representations helps to characterize students' understandings and their misconceptions. Stacey Lowery Bretz shared multiple resources and strategies for using them in her ChemEd X Talk. The recording is available here!
This short activity uses Elmer’s Disappearing Purple Glue as an interactive introduction to acid-base indicators.
Nora Walsh outlines the interactive notebook pages she uses for her unit on the Periodic Table. All of the documents and foldables are available for download.
Learn a bit about the chemical reactions that occur during a lightning strike, and how you can demonstrate these reactions in your classroom.
"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.
