We will be using triple-beam balances to find the mass of various
objects. The objects are placed on the scale and then you move the
weights on the beams until you get the lines on the right-side of
the scale to match up. Once you have balanced the scale, you add up
the amounts on each beam to find the total mass. What would be the
mass of the object measured in the picture? _______ + ______ +
_______ = ________ g
Slide 20
Measuring Mass Triple-Beam Balance Click here to try an online
activity. 1 st Place the item on the scale. 2 nd Slide the large
weight to the right until the arm drops below the line. Move the
rider back one groove. Make sure it locks into place. 3 rd Repeat
this process with the top weight. When the arm moves below the
line, back it up one groove. 4 th Slide the small weight on the
front beam until the lines match up. 5 th Add the amounts on each
beam to find the total mass to the nearest tenth of a gram.
Slide 21
Digital Scales How do I use a digital scale? What is the
difference between the CS200 scale and the CS2000 scale?
Slide 22
Example Problem: What is the temperature in C of a 256 K
object? Solution: The conversion formula for C to K is TC = (TK) -
273 TC = 256 - 273 TC = -17 C Answer: The temperature in Celsius of
a 256 K object is -17 C.
Slide 23

Bottom Image: http://morrisonlabs.com/meniscus.htm We will be using
graduated cylinders to find the volume of liquids and other
objects. Read the measurement based on the bottom of the meniscus
or curve. When using a real cylinder, make sure you are eye-level
with the level of the water. What is the volume of water in the
cylinder? _____mL What causes the meniscus? A concave meniscus
occurs when the molecules of the liquid attract those of the
container. The glass attracts the water on the sides.

Metric Conversions Ladder Method T. Trimpe 2008
http://sciencespot.net/
Slide 63
Metric Conversion: Stair-Step Method The Metric System of
measurement is based on multiples of 10. Prefixes are used to
indicate what multiple of 10 the base unit is being multiplied by.
The prefix Kilo (k) - means 1000 times. The prefix Hecto (h) -
means 100 times The prefix Deka (dk) - means 10 times. The prefix
Deci (d) - means 0.1 times. The prefix Centi (c) - means 0.01
times. The prefix Milli (m) - means 0.001 times.

Test No talking Phones need to go in the box. If I see you with
your phones you get a zero. No questions asked. Dont write on the
test itself. Show work on the answer sheet, it might earn you some
