5516
Chemistry set

The four kits mentioned below:
5510 Physical and chemical phenomena
5511 General chemistry basis
5513 Electrochemistry
5515 Organic chemistry
They can be bought separately or as a unique set with a lower cost than the global cost of the four kits because some parts that are repeated in the 4 kits are eliminated when buying the set. The contents and the possible experiments of the set correspond to the sum of those contained in each kit. The kits permit experiments related to topics that are part of Chemistry lessons plan in senior high schools.
Two main features that make the set particularly efficient:
– quick assembly of the different parts and ease of use. These features meet user safety and same time;
– Contents clearly and unambiguously explained.
Each kit is supplied with a teaching guide in which every practical experiment is explained in detail.
At the end of every experiment there’s a series of questions about the observed phenomena.
These kits are an essential aid for teachers and can also be useful for students collective experiments on specific subjects.
