1. Activity 14: Physical and Chemical Properties of Materials
Page # Date
White space Question or Prompt:
Describe at least 3 properties of aluminum, glass, and plastic.
Aluminum:
Glass:
Plastic:
Challenge/Question: How do the properties of materials determine their uses?
Investigation Notes & Hypothesis: Take notes on the physical and chemical properties we will investigate (next slide).
Vocabulary: Review physical and chemical properties.
Procedure: I understand
Materials: Check off 

2. Investigation Notes Testing Properties:
Light transmission: Does light pass through the material?
Luster: How does light reflect off the material (is it shiny or dull)?
Texture: How does the material feel?
Flexibility: How easily does the material bend?
Hardness: Can the material scratch glass?
Reaction to Hydrochloric Acid: Does the material react with the acid?

3. Physical Property
A characteristic observed with the senses; can be observed without changing or trying to change the composition of the substance.
(EX: color, shape, length, state)

4. Chemical Property
A characteristic that cannot be observed without altering the substance. Describes how a material reacts with another substance.
(EX: flammability, the ability to rust)

5. Activity 14: Physical and Chemical Properties of Materials (con’t)
Data/ Observations:
Insert Student Sheet 14.1 “Testing Physical and Chemical Properties.”
Record the groupings you have put the materials into (Procedure Step 3).
Conclusion/ Analysis Questions:
Answer Analysis Questions 1-4 (pg. B-17 & 18) aloud together and record in lab notebook.
Notes to myself/ Exit Ticket: Which property did you like testing for the best?
