CW#6 finding irregular volume

Lw#3 Volume by displacement

DUE Friday• Hw #5 Science Skills

Week 5: Thursday Sept 10, 2015

Set up your next blank notebook page as shown below

Lw #3 Finding volume by displacement

Purpose: Learn the proper procedure for calculating the volume of an object by displacement

OBJECTS TESTED INITIAL VOLUME OF WATER

(mL)

FINAL VOLUME OF WATER(mL)

VOLUME OF WATER

DISPLACED (mL)

VOLUME OF OBJECT (CM3)

DATA TABLE: VOLUME OF IRREGULAR-SHAPED SOLIDS

You will be measuring 8 objects

Lw # 3 Finding Volume by Displacement

Keep the beaker on the blue tray to avoid dripping on the table

Place fingers over the GC when emptying the water to avoid breaking the beaker

Make sure you answer the ANALYSIS questions in complete sentences that restate the question.

Clean-up Procedures1. Empty the water from the GC into the beakers

2. Place ALL 8 objects in the plastic container3. Place all materials on the blue tray4. Place blue tray on front table5. Stack green lab sheets in the “hands-free”

zone at the end of your table6. Continue working on CW #6 Metric

Measurement

2. How do you measure the volume of a RECTANGULAR SOLID??

Use a ruler Use the equation (L x W x H)

6 x 3 x 6 = 108

6 x 6 x 3 = 108

3 x 6 x 6 = 108It doesn’t m

atter what order!!

2. How do you measure the volume of a RECTANGULAR SOLID??

To determine VOLUME you MULTIPLY THE SIDES (L x W x H)

10 cm

9 cm

8 cm

We can measure the volume of regular object using the formula length x width x height.

_____ X _____ X _____ = _____

COPY THEN ANSWER!

2. How do you measure the volume of a RECTANGULAR SOLID?

RECTANGULAR volume is measured in CUBIC CENTIMETERS (cm 3) 1cm

1 cm

1cm

3. What are the units for solid VOLUME?

1 cm x 1 cm x 1 cm = 1 cm 3

even irregular solids are measured in cm3

1 milliliter = 1 cubic centimeter (cm3) or 1 c.c.

1 ml = 1 c.c.
