CHEMICAL REACTIONS
What Is a Chemical Reaction? Student Laboratory Kit
How can students identify a chemical change? In this microscale experiment, students study the properties of hydrochlo- ric acid and copper(II) chloride with a variety of substances to observe and identify signs of chemical change. Includes reproducible student handouts, detailed background information, complete Teacher Notes with sample data and answers to questions and all necessary chemicals and consumable supplies.
AP6269 I $44.60
Metal, Nonmetal or Metalloid? Student Laboratory Kit
In this introductory kit, students explore the unique physical and chemical properties of eight elements with the goal of classifying them as metals, nonmetals or metalloids. Students investigate the color, luster, over- all appearance, malleability, conductivity and various chemical reactions of sample elements. Complete for 30 students working in pairs. Student conductivity meters are recommended and available separately.

Elements, Compounds and Mixtures—Super Value Laboratory Kit
Includes four activities:
• A paper-and-pencil activity familiarizes students with common element symbols and names.
• A “classification of matter” activity uses a flow chart to classify materials as elements, compounds or mixtures.
• A lab activity lets students 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.
Super Value Kit is complete for 5 classes of 30 students working in pairs.

Gluep Production— Guided-Inquiry Kit
Student research teams are challenged
to use the scientific method to improve a polymer recipe and make a bouncier Gluep ball—all while staying on a fixed budget. Complete for 30 students working in pairs.

In this guided-inquiry lab, students observe a standard test method for iron corrosion and examine the evidence for the electrochemical model of corrosion. They then design a “fair test” experiment, using the standard method, to determine the validity of their hypothesis. By reviewing results with those of other groups, students are able to compare the effectiveness, advantages and disadvantages of various methods of corrosion protection.
