1 Activity 14: Physical and Chemical Properties of Materials 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 Page # Date

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: 1)Insert Student Sheet 14.1 “Testing Physical and Chemical Properties.” 2)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?
