I was very disappointed to receive a fake tub with often void materials worth just a few dollars. This kit must be priced at $30-$40, and even that would be generous. The chemicals are Sodium Chloride (table salt!) and calcium chloride void as DampRid for $1.00 at any Home Depot for this amount! A bunch of foam and fake cups. OK, a few thermometers. Able idea to make money off...TEACHERS! Shame on you, Hubbard Scientific! Shame on me for being too busy instruction and falling for such an overpriced product.I quickly (surrounded by two days) mailed it back, and the Amazon send somebody a proclamation showed that it was expected, yet I expected an email that it was never returned, and that my credit card was charged for it!

They then tell these two principles of Gibbs free energy and gather to characterize between exothermic, endothermic and isothermic reactions. Includes Teacher's Guide, apprentice worksheet and MSDS. For grades 9-12. Class size: 30 students.
