1 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?

2 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.
