This is a chemistry, self-extracting file for level 4-9 teachers. After extraction, 106 skeletal molecular-model files are available. Each file can be opened in the freeware ChemSketch 2015 program. Both spacefill and ball-&-stick rotatable models can be viewed.
Some, but not all, of the esters are fruit aromas. Download the 119-page, TpT product, "Book 5 Aromas, Fragrances, and Odors (Enrichment Chemistry Series)" for examples. Aromas are a superior way to introduce chemistry to the lower grades.
