1. August 9, 2017 Agenda & notebook should be on table
WORK MODE: SILENT
Agenda & notebook should be on table
Complete the Phase Diagram side of the worksheet (the “Y”)
Read both sides of the handout – add to your notes if needed.
Revisit your warm-up from yesterday to see if you want to change any ideas
Homework: Read chapter 3, section 2. Know the gas laws. Be prepared to discuss (take notes if needed). USA Test Prep due Friday.

2. Think!
In your notebook, write down three questions about how the plasma ball works
Share your questions with your group
Discuss and develop a hypothesis
WORK MODE: WHISPER

3. Think!
After reading through the handout, look at your questions and hypotheses from yesterday
Discuss your new information.
Can you answer your questions?
Can you refute or refine your hypothesis?
WORK MODE: WHISPER

4. Compare & Contrast
Observe the two different models (pictures) representing the states of matter
How are the two similar and different?
How do the representations of plasma help you understand how the plasma ball works?

5. How can we explain the differences among solids, liquids, and gases?
Spacing of Molecules
Energy of Molecules
Solid
Liquid
Gas
Use words such as least, medium, most, closest, medium, farthest, etc.

8. August 9, 2017 Have notebook & agenda on table
Complete both sides of the worksheet
Homework: Review for quiz! Read chapter 2, section 2. Be prepared to discuss (take notes if needed). USA Test Prep due Friday.

9. Quiz Tomorrow Know the definition of chemical and physical properties
Know the difference between chemical and physical properties
For CHEMICAL properties, know REACTIVITY and FLAMMABILITY/COMBUSTABILITY
For PHYSICAL properties know the measurement terms from chapter 2, section 1 (volume, mass, weight) and the terms on page 45 (conductivity, state, density, solubility, ductility, and malleability)

10. Describing Matter You have 4 “mystery powders”
In your notebook, create a bubble map for 2 of the substances on your table (label with the powder’s number)
Try to find FIVE descriptive terms for each substance
What were some observations that you made?
Did you have to change the substances to make these observations?
Many of these observations are PHYSICAL PROPERTIES

11. Observing how matter interacts
You have two liquids
The brown liquid is IODINE
The clear liquid is ACETIC ACID
When directed, place a drop of each on each powder
Record your observations in your notebook in a table
Powder
Iodine
Acetic Acid 1 2 3 4

12. Observing how matter interacts
Powder
Iodine
Acetic Acid 1
No reaction (stayed brown)
No reaction 2
Reaction (bubbled) 3
Reaction (turned black) 4

13. Can you match the powders?
Baking Soda
White, powdery solid
Reacts to acetic acid
Non-reactive to iodine
Cornstarch
Non-reactive with acetic acid
Reacts to iodine
Salt
White, crystalline solid
Non-reactive to acetic acid
Sugar

14. Physical and Chemical Properties
Help us identify substances
Pure substances such as elements and compounds have definite properties
Physical properties include color, taste, texture, density, boiling point, and melting points
Chemical properties include reactivity and flammability

15. Did you see a reaction?
When you change your substance while testing it, you are looking for CHEMICAL PROPERTIES
