Chemical Education Today Especially for High School Teachers by Erica K. Jacobsen Chemistry in My Kitchen The Jacobsen kitchen is an unusual place. The atmosphere is often more “mad scientist” than “gourmet chef ”. Testing JCE Classroom Activity procedures at home brings an eclectic collection of materials to our counters. Our toaster competes for space with a collection of funnels made from 2-liter plastic beverage bottles and rubber stoppers (1). Baking soda from my shelf joins citric acid

Year 11 Module 1 – The Chemical Earth The Earth is made up of a large number of different substances: elements‚ compounds & mixtures We can classify elements & compounds as pure substances. These are always HOMOGENEOUS. Mixtures are not pure substances and can be either homogeneous or HETEROGENEOUS. Pure substances have a fixed composition eg copper metal‚ sulfur‚ carbon dioxide (CO2)‚ methane (CH4). Mixtures have variable composition and can also be separated into its components relatively

Multistep Synthesis of Tetraphenylcyclopentadienone In this laboratory experiment a synthesis was performed through several separate steps. The purpose of the experiment was to synthesize tetraphenylcyclopentadienone from benzaldehyde and to run reactions on carbonyl containing compounds. There was a total of three steps that led up to the synthesis of the final product‚ tetraphenylcyclopentadienone. The first step of the experiment was the condensation of benzaldehyde to yield
