Thin sheets of polystyrene can be patterned with permanent markers to represent repeating units of the polymer and then shrunk down in size using heat. The shrunken models of the repeating units can be connected with a string and then flipped into positions to demonstrate different types of polymer tacticity.
This is the third in a series of classroom activities using paper tools to teach organic nomenclature. This post covers the two common naming systems used for carboxylic acids and derivatives, and second for alcohols, thiols, ethers, amines, and ketones.
What does a recent visit to Fort Bridger State Historic Park in southwestern Wyoming, a plant similar to an onion, and an armed conflict between Native Americans and the US government have anything to do with chemistry? Much. Check it out here.
Who is not interested in food, right? Why not use what happens in the kitchen everyday to teach some chemistry? This blog post shares some conceptually based questions based on the information found on the backside of a popular dry mix brownie product.
To help introduce students to organic nomenclature in a way that clearly summarizes the patterns that exist in the IUPAC system, a series of paper tools were developed. The paper tool in this activity can be used to introduce the IUPAC naming of major classes of organic compounds. These paper tools are easy to print and distribute to every student each semester.
Organic nomenclature is usually taught as an introduction to organic chemistry. To help introduce students to organic nomenclature in a way that clearly summarizes the patterns that exist, a paper tool for naming hydrocarbons was developed.
Cold weather brings about the opportunity to demonstrate glass transition temperatures of polypropylene containers.
Michael Morgan shares a lesson that he has used for many years that not only requires students to explain a topic that they have not been directly taught but also to develop explanations based on previous knowledge. He has used this lesson as a multiday “in-class” assignment and also as an “at-home” independent study. It works well in both scenarios with only minor revision. The lesson is based on Alfred Werner’s work on deducing the structures of coordination compounds.
Desmos offers an activity building feature that allows teachers to create and customize activities. The resource is applicable to a variety of science and chemistry topics and useful in whatever learning environment teachers find themselves in next school year.
"A bear is wiser than a man because a man does not know how to live all winter without eating anything." Abenaki (People of the Dawn) saying. This is the third post describing the metabolic and nutritional chemistry of bear hibernation.
