Cornell Notes – Due Now

Quick Writes will not be grade for points but for participation and honesty.

1. You are allowed to use your brain, any notes, labs or worksheets we have done in class.

2. You may not use your textbook or interactive reader.

3. You will have 10 minutes to complete as many questions as possible.

4. With a colored pencil, you will grade your own.

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.

Method #1: With a Liquid Illustrate & Color this on your paper.

Meniscus

•The unit of measurement is usually in mL or L or cc

Cube and Rectangle Volumes are found by measuring their Length X Width X Height

BASE =

The unit of measurement is usually in mL or cm3……or any cubic unit

AREA

Method #2: With a Regular Shape Object

-cm3 = mL = cc

-A cube 1x1x1 cm can hold 1 mL of water.

cc stands for Cubic Centimeters

EQUIVALENT MEASUREMENTS

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

-Use DISPLACEMENT….the amount of water pushed out of the way by an object

-The unit of measurement is usually in mL or cm3 or cc

Method #3: With an Irregular Shaped Object

Initial Height of Water

350 mL

1st Water Level

Method #3: With an Irregular Shaped Object

Initial Height of Water

350 mL 350 mL

Place object into water and read level again.

1st Water Level 2nd Water Level

Method #3: With an Irregular Shaped Object

Initial Height of Water

350 mL

425 mL

Place object into water and read level again.

1st Water Level 2nd Water Level

Method #3: With an Irregular Shaped Object

Initial Height of Water

350 mL

425 mL

Place object into water and read level again.

1st Water Level 2nd Water Level

Method #3: With an Irregular Shaped Object
