Review how to measure volume of liquids, regular and irregular shaped objects.

3. Identifying Volume There are THREE way to find volume in the chemistry classroom. You will need to know them in order to help you eventually determine the density of various objects . REMEMBER : Volume is the Amount of Space something takes up.

5. Cube and Rectangle Volumes are found by measuring their Length X Width X Height BASE = The unit of measurement is usually in mL or cm 3 ……or any cubic unit AREA Method #2: With a Regular Shape Object

6. - cm 3 = mL = cc - A cube 1x1x1 cm can hold 1 mL of water. cc stands for C ubic C entimeters EQUIVALENT MEASUREMENTS

7. Identifying Volume Cube Rectangle Prism L x W x H L x W x H (½ L x W) x H Method #2: With a Regular Shape Object b x h a x h ½ b x h

8. - Use DISPLACEMENT ….the amount of water pushed out of the way by an object - The unit of measurement is usually in mL or cm 3 or cc Method #3: With an Irregular Shaped Object

9. Identifying Volume Initial Height of Water 350 mL 1 st Water Level Method #3: With an Irregular Shaped Object

10. Identifying Volume Initial Height of Water 350 mL 350 mL Place object into water and read level again . 1 st Water Level 2nd Water Level Method #3: With an Irregular Shaped Object

11. Identifying Volume Initial Height of Water 350 mL 425 mL Place object into water and read level again . 1 st Water Level 2nd Water Level Method #3: With an Irregular Shaped Object

12. Identifying Volume Initial Height of Water 350 mL 425 mL Place object into water and read level again . 1 st Water Level 2nd Water Level Method #3: With an Irregular Shaped Object Subtraction Problem 2 nd water level - 1 st water level 425 mL - 350 mL 75 mL

13. Identifying Volume Item Type of Volume Measurement Needed (Method #) Why ? Tomato Sauce # Rectangular Wax Candle # Sponge Bob Plastic Toy # Box received in the Mail #
