1 DO-NOW Volume 0 Use complete sentence and complete your Do Now in your comp book. Georgia was absent last week. Please write her a text explaining how to find density. Include the formula and the names of the tools you need.

2 Today’s Schedule 1. Do-Now 2. Finish Density Lab
3. Density Practice/Check 4. Microchemistry Objectives: Today we will… 6.6   (B)  calculate density to identify an unknown substance 8.5 (E) investigate how evidence of chemical reactions indicate that new substances with different properties are formed Dark Matter

3 Take 5 minutes to finish your density lab.
Voice Level 0 Take 5 minutes to finish your density lab. Please double check your calculations. Show all work. When you are done begin on the Density Practice.

4 Observing Chemical Reactions
Chemical A Cobalt Nitrate Calcium Carbonate Sodium Bicarbonate Chemical B Ammonium Vannidate Na3PO4 H2O Acetic Acid Observations before and after.

5 Evidence of Chemical Reactions
1. 2. 3. 4.

6 Evidence of Chemical Reactions
Gas formed (bubbles/odor) Color Change Heat absorbed or released (gets hot or cold) Precipitate formed (mix two liquids and solid forms) Evidence of chemical reactions indicates that new substances with different properties are formed.

7 Exit Ticket Complete the following on the sticky note at your desk.
You know a chemical reaction has happened if you observe… 1. 2. 3. 4.

9 Draw/color a picture showing what we learned today.
Observing Chemical Reactions Conclusion: Today we investigated chemical reactions. In our experiment we observed… The most interesting thing was… One question that I still have about chemical reactions is… Draw/color a picture showing what we learned today.

10 Work with your shoulder partner.
1. Underline: Physical Changes Chemical Changes 2. Write evidence for a chemical change. (page 11)

11 I know a chemical change has taken place when I observe…
