On Target? Do this on your Warm Up worksheet! PLEASE put today’s date (2/8/16) in the top box on your warm-up! What does the word “relative” in the phrases “relative hardness,” “relative melting point,” and “relative solubility” mean? How do we use relative to group things together?

For today 1.Warmup 2. Chemical Formulas 3.Categorizing substances Objective: I can test properties of different substances in order to categorize these substances by recording accurate data throughout this lab activity.

Data from scientists

Macroscopic Categories of Compounds On your whiteboard: Categorize (group by similarities) all tested compounds and make a chart that includes: 1.Name of category 2.List of compounds that belong in it 3.Description of the common properties. *FOCUS ON MELTING POINT AND CONDUCTIVITY IN WATER!*
