› Physical properties- characteristics that can be observed or measured without changing the substance into something else in the process.
› Chemical properties- traits of a substance that you find by seeing if it reacts in certain ways with other chemicals.
› Miscible- a substance is able to mix with another liquid. Non-miscible liquids separate into layers or bead.
Activity 6In Case You Missed It…

› THIS FRIDAY I will be looking at your notebooks.
› Scoring guide on OneNote
› 2 pages for each activity. 1 for notes, 1 for analysis questions– Example: Activity 1, Activity 1 Analysis Questions
› Labels (In Case You Missed It, Student Sheets, homework)
› POINTS CHANGED- 20 pts for classwork only.
OneNote Notebook Check

› This Friday!
› Be sure to have your notebook organized, cleaned up, labeled, and easy to read!
› The questions will not be as simple as the previous quiz!

› Density related to water-
Testing Solids Demo

› Water has a density of 1.0 g/cm3
› Ethanol has a density of 0.79 g/cm3
› Objects with greater density than 1.0 g/cm3 will sink in water. Objects with density less than 1.0 g/cm3 will float.
› Titanium has a density of 4.3 g/cm3. Would it float in water? Would it float in ethanol?
› This test shows relative density, not exact!
A Note about Density

› Test each solid just as I have in the demos.
› Remember lab safety! You need goggles; if they are not on your eyes, it is an automatic Last One Out!
› Record results on “Properties of Separated Solids” on Student Sheet 7 in the OneNote content library.

› On your own, with a partner, or with your group, work on Analysis Questions 2-4.
› They should be done in your OneNote notebook.
› Make a new page for the questions. Title it “Activity 7 Analysis Questions.”
› Also, look up the densities of copper, Styrofoam, and aluminum. Would they float or sink in water and ethanol?
›OMIT #1 and #5!
