Triple Beam Balance instructions and homework

Here are 2 links on how to use the Triple Beam Balance. Just click on the links below:

Reminders:

Triple Beam Balance- used to measure the mass of objects.

uAlways carry a T.B.B. by the base, not the beams!.

uBefore you calculate the mass of an object, make sure the riders are at 0.

uThen calibrate the T.B.B. by turning the little knob at the end (indicator)! But make sure the table is still and its NOT moving.

Density Summary

Class, this is information we've learned about Density in class. You can click on the pictures to make them bigger. Memorize this information and let me know if you have questions:

PROPERTY	SYMBOL	UNIT
Density	D	g/ml (liquids), g/cm3 (solids)
Mass	m	g
Volume	v	mL (liquids), cm3 (solids)

To calculate the VOLUME of a regular-sized object, remember to multiply it's Length, Width, and Height.  V = L x W x H

And to calculate the MASS of an object, you place the object on a Triple Beam Balance (shown below) and you add up all 3 beams (round to the nearest tenth):

Metric System vs U.S. System of measurments

Class, this is an excellent website that teaches you the difference between the Metric system and the U.S. (or English) system of measurements. Just click on here- Metric vs U.S. system

This image shows the difference in units between the English and Metric system.

These 2 images show the frequently used units of the Metric system and their symbols.

This video from Bill Nye discusses the Metric system in more detail:

Homework on Weight & Mass

For all my Classes, click on this link--> Weight & Mass worksheet     This will be your homework over the weekend. Write the questions and answers in your notebook. OR you can print it out and show it to me with the answers. Also, write both "Content Clues" statements into your notebooks. It's on the right side of the worksheet. It is due this Monday, November 24th. Write to me if you have any questions.
