Food chemistry is an interesting and fun class for students. Read the article for some suggestions about resources along with an outline of a unit developed around water in cooking.
The lab was a success as I watched startled students produce the so-called barking dog sound as they combusted the hydrogen gas in their inverted test tubes.
A 2L soda pop bottle is filled about one-third full with either liquid nitrogen or solid carbon dioxide (dry ice) and water. The bottle is sealed and a plastic bucket is placed on top. Do you think the liquid nitrogen or dry ice and water will make the bucket go higher? Can you explain the results using chemistry?
Addition of a white solid to a green solution causes the solution to separate into some truly beautiful colors...
My plans for the introduction of the periodic table for my chemistry course. Resources include a document that I use to help students with vocabulary and key points as well as my recommendation for a Target Inquiry activity to use with your students.
The purpose of a lab practicum is to assess a student’s understanding of the content by completing a hands-on challenge. These assessments focus more on problem-solving skills than technique.
This activity was submitted for a 2016 ChemEd X Call for Contributions soliciting input regarding the big ideas being put forth by organizations like AP. The author shares a lab activity that relies on connections - between stoichiometry, esterification, equilibrium, kinetics, titrations and uncertainty of calculations. He also shares the resources he created.
Like most chemistry teachers, one of the first things I go over in the beginning of the year is unit conversions. Students come into my class with all sorts of prior knowledge concerning unit conversions; some good, some bad and some downright ugly.
Throughout the last ten years teaching both chemistry and Advanced Placement Chemistry I have realized that the concept of equilibrium does not receive enough attention in my first-year chemistry course. Sure, the concept of equilibrium is a topic mentioned and identified throughout the course however the dialogue in regards to conditions that would shift the chemical system is minimal at best.
Although not a chemistry app, I have been using Classkick(link is external) in my chemistry class strictly as a formative assessment tool and wanted to share the many benefits I have found with it. Classkick is a free app that is currently available through the itunes(link is external)store. I use it with the iPads I have in my classroom. Soon, classkick will be available on other devices besides just the iPad.
