2. Okay, let’s think about the following…

3. Glass Basketball Brick Pillows Rubber Knife Furry Dishes Sand Paper T.P.

4. Structure - Function THEY HAVE TO AGREE!!! So how do we make that happen?

5. By observing the PHYSICAL PROPERTIES! A PHYSICAL PROPERTY is a characteristic that can be observed or measured WITHOUT changing the identity of the matter. That’s the title of your paper! That’s important, write it down!

6. We observe properties in two different ways. Round Gray Rough Solid 8 cm long 125 grams 22 holes Can you tell the difference???

7. Qualitative Observations - QL We observe quickly and easily with our … That’s important, write it down!

8. Quantitative Observations - QN Some observations we have to work for… That’s important, write it down!

9. A Quick Way to Remember QL ook (our senses) QN umbers (count or measure) You may want to add this to your notes!

10. Let’s Learn Some Physical Properties You will be learning about 15 important physical properties that help us determine what an unknown material is or how we should use a material. For each property you need to write four things. 1.The name 2.QN or QL 3.The definition 4.An example or sketch

11. COLORCOLOR How an object reflects light

12. LUSTER How shiny it is Any guesses?

13. SHAPE The form of the object What property could this be?

14. TEXTURE How something feels Soft Hard Fluffy Smooth Slick Wet Rough Warm

15. LENGTH Measurement from one point to another point

16. Practice Teacher model on the document camera. INCHES DO NOT EXIST IN SCIENCE!!! Students, what is the EXACT width of your desk?

17. MASS Amount of matter something is made of How is it measured?

18. Practice Teacher model how to use a triple beam balance. What is the mass of the object on this scale? Students. What is the mass of your tissue box?

19. VOLUME Amount of space taken up L x W x H Water Displacement

20. Practice Teacher model volume of a regular shaped object. Students, what is the volume of your tissue box?

21. Practice Teacher model volume of an irregular shaped object. Students, what is the volume of the objects below?

22. DENSITY Mass per unit volume of a substance (mass volume) I love density: mass volume Very denseNot as dense mVmV

23. Demonstration Colorful Columns – draw a column tower and predict how the following liquids will layer based on their densities: Water Oil Corn syrup Rubbing alcohol

24. STATE Physical form in which a substance exists SOLID LIQUID GAS PLASMA

25. Sketch

26. Thermal Conductivity The rate at which a substance transfers thermal (heat) energy. GOOD POOR

27. SOLUBILITY Ability of a substance to dissolve in another substance DissolvesWill not dissolve

28. DUCTILITY (can you tell) Ability of a substance to be pulled into wire

29. Demonstration Silly Putty

30. MALLEABILITY (ever heard of a mallet???) Ability of a substance to be rolled or pounded into sheets such as…

31. ELASTICITY Ability to return to original shape

32. HARDNESS How easily it can be scratched

33. Practice
