Today's science lesson will focus on identifying volume through three methods: 1. With liquids by measuring the level in mL or L 2. With regular shaped objects like cubes or rectangles using length x width x height 3. With irregular shaped objects using the displacement method of measuring the change in water level in mL Students will need pencils, colored pencils, lab worksheets, and power notes to participate in identifying volume activities and assignments.

1. Today in Science Today you will need : Pencil, Colored Pencils Identifying Volume Lab Worksheets (Bookshelf – 2 sheets/4 sides) Power Notes – Physical vs. Chemical due NOW (Did you do R&R?)

2. Notices Update Log #2 – New work Test Retakes – Some people still have not taken it the first time. Please schedule w/me

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.

4. Identifying Volume Method #1: With a Liquid Illustrate & Color this on your paper. Meniscus The unit of measurement is usually in mL or L or cc

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 1 Liquid 2 Regular Shaped Object 3 2 Irregular Shaped Object Regular Shaped Object Item Type of Volume Measurement Needed (Method #) Why ? Tomato Sauce # Rectangular Wax Candle # Sponge Bob Plastic Toy # Box received in the Mail #

14. Grading Math Problems in Science 5 points given: 2 points for the problem you are inputting into the calculator 2 points for the answer rounded to the nearest hundreth 1 point for the unit label

15. Volume Practice – Displacement & Regular Shapes Show work Answers will be graded for correctness Complete Volume Assignment by Tomorrow.
