A great, high-quality introductory kit—ideal for teaching the concepts of elements, compounds and mixtures. Four separate activities are provided.
- The first paper-and-pencil activity will familiarize students with common element symbols and names.
- In the second “classification of matter” activity, students use a flow chart to classify various materials as either an element, a compound or a mixture.
- Next is a laboratory activity in which students use physical separation techniques to separate a mixture consisting of sand, salt, zinc and iron filings.
- Then students chemically react aluminum with copper(II) chloride to produce and isolate a new element and compound.
Detailed Teacher Notes and reproducible student handouts include easy-to-follow lab instructions, sample data, answers to questions and in-depth background information. All chemicals and specialized equipment are provided.
Super Value Kit is complete for 5 classes of 30 students working in pairs. One magnetic wand is included with the kit—additional wands are available separately.
