Good posters, contain solid information on atoms,molecules, elements, and compounds. Great fit for my sophomore chemistry classroom. Nice worksheets also came along with it. Would recommend for teachers.Thursday, September 25, 2014
Reviews of Teaching Poster Set: Atoms, Elements, Molecules & Compounds; no
These posters aren't very accurate, which was pretty disappointing. They show that H2O2 (hydrogen peroxide) is bonded O-H-H-O, which anyone with a few weeks of chemistry knowledge knows is impossible. CO2 is shown to be a bent molecule, but it's not. The examples just don't make sense and the diagrams aren't even slightly accurate. Good decorations for a science classroom where nobody is really reading the posters.
