Warm-Up: Explain some characteristics of liquids. What makes them a liquid?
Learning Target: I can investigate and determine different properties liquids have in a specific mixture.
Success Criteria: I will be successful using various properties to identify liquids.
Plan for Today
1. Vocabulary
2. Physical & Chemical Properties
3. Liquid Investigation
4. Analysis Questions/Worksheet

2. What are the liquids in the mixture?
CHALLENGE Question:
What are the liquids in the mixture?

3. Vocabulary
Physical Properties: a characteristic of a substance or material; color, density, flexibility
Chemical Properties: a specific result of a test with a chemical reaction; pH, color change, salt production
Miscible: two or more substances that can be mixed together in any ratio to form a single phase without separation; mixes = miscible, not mixes = not miscible

4. Tests/data collection being done:
appearance
miscible in water
miscible in ethanol (alcohol)
contains water
corrosive
toxic
flammable
Liquid A or B flammable?
(Demo and fill in 6.1.)

8. ANALYZE RESULTS BELOW TO IDENTIFY LIQUID A and LIQUID B

9. Finish your Analysis Questions. WORK ON YOUR ATOM TIMELINE!!!
DONE? Awesome!
Please CLEAN-UP!
Finish your Analysis Questions.
Still have more time?
WORK ON YOUR ATOM TIMELINE!!!

10. ANALYSIS: A 24 Q1 Q2 Q3
Table 2 says Liquid A is mineral oil because not corrosive, is flammable - but is NOT toxic.
Table 2 says Liquid B is iron nitrate because it is toxic but not flammable, it IS corrosive.
Table 2 says Liquid B is more hazardous because it is toxic and corrosive (Liquid A is not – only flammable).
Update WS 5.1 with Hazards" Yes" or "No"

11. What are the liquids in the mixture?
ANSWER CHALLENGE Question:
What are the liquids in the mixture?
The mixture's liquids are:
A = mineral oil
B = iron nitrate
