1 Activity 14: Physical and Chemical Properties of Materials Page # DateWhite 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 understandMaterials: 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 PropertyA 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 PropertyA 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?
