1. On Target? Do this on your Warm Up worksheet! How do you categorize your clothes? Why would chemists categorize chemicals?

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

3. Today: Testing Table Salt, Epsom Salt and Sugar No goggles needed Work as a group!

4. DO NOT WRITE! How will you test the properties? Property SUGAR Appearance What it looks like Hardness Soft, powder, crystals, etc. Conductivity SOLID Conductivity meter: Low, Medium, High Soluble in water Put in water and stir: Yes, no, maybe? Conductivity in WATER Conductivity meter: Low, Medium, High Melting point Flame test: put over burner and look for when it melts Bond type NOT observable but the other properties are good clues.

5. Particular Properties PropertySUGARSALT EPSOM SALT Appearance What it looks like Hardness Soft, powder, crystals, etc. Conductivity SOLID Conductivity meter: Low, Medium, High Soluble in water Put in water and stir: Yes, no, maybe? Conductivity in WATER Conductivity meter: Low, Medium, High Melting point Flame test: put over burner and look for when it melts

6. WHEN FINSIHED… On each post-it note, write: Name of Substance (sugar, salt, Epsom salt) Name of property (Appearance, hardness, conductivity solid, soluble in water, conductivity in water) Your observation Then place on class data table whiteboard!
