1. Bell Work! Look at the item on the front lab table.
Write down as many descriptive words as you can to describe the object.

2. Properties of Matter Chapter 7
A physical property of matter can be OBSERVED or MEASURED without changing the matter’s identity.

3. EXAMPLES of PHYSICAL PROPERTIES
States of Matter
The physical form in which a substance exists (solid, liquid, gas).
Ice is water in a solid state.

4. What state is this?

5. What state is this?

6. What change is this?

7. What change is this?

8. EXAMPLES of PHYSICAL PROPERTIES
Density
The mass per unit volume of a substance
Lead is very dense, so it makes a good sinker for a fishing line.

9. EXAMPLES of PHYSICAL PROPERTIES
Solubility
The ability of a substance to dissolve in another substance
Flavored drink mix dissolves in water.

10. EXAMPLES of PHYSICAL PROPERTIES
Volume
The amount of space an object takes up

11. EXAMPLES of PHYSICAL PROPERTIES
Mass
The amount of matter in an object

12. EXAMPLES of PHYSICAL PROPERTIES
Malleability
The ability of a substance to be rolled or pounded into thin sheets.
Aluminum can be rolled into sheets to make foil.

13. EXAMPLES of PHYSICAL PROPERTIES
Ductility
The ability of a substance to be pulled into a wire.
Copper is ductile…so most wiring is made of copper.

14. EXAMPLES of PHYSICAL PROPERTIES
Thermal Conductivity
The rate at which a substance transfers heat.
Styrofoam is a poor conductor…so you want to use it to hold your hot drink so your hands don’t burn.

15. Let’s focus on VOLUME! Page 35
Find the volume of irregular and regular shaped solid objects using water displacement and the formula for volume.
If the object is “regular” shaped, we will use a ruler and a formula.
It the object is “irregular” shaped, we will use a graduated cylinder.
Page 35

16. Regular Solids = Length • Width • Height

17. Volume of a solid (even if measured using a graduated cylinder) is expressed in cm³.
Let’s practice… Sarah wanted to see if her carry on bag would fit in the overhead storage on the plane so she measured her luggage before she left the airport. She recorded her measurements in the table below. What is the volume of Sarah’s bag?
500 cm³
LENGTH
WIDTH
HEIGHT
Sarah’s Luggage
5 cm
10 cm

18. Let’s practice… Jack found a new case for his cell phone
Let’s practice… Jack found a new case for his cell phone. It had a height of 2 cm. It was 3 cm in length and was 1 cm wide. What was the case’s volume?
6 cm³

19. Volume (of Irregular-Shaped Solid)= water displacement technique
New Measurement
-First Measurement
Volume of Solid Object
Volume of Ring = 68 – 64
4 cm³

20. Object #1: Block Object #2: 10 pennies Object #3: 3 paperclips
At the lab table, find the volume of the following objects. Keep all your data on the index cards provided at each lab table. Every student needs their own card.
Object #1: Block
Object #2: 10 pennies
Object #3: 3 paperclips
Decide what method would be best.
Be sure to write down your data…you will need it later.
Clean up thoroughly before sitting down.
Pick up a Volume WS.
