Exam Experience Part 1-12/19/12-Dani Swords
unit of measurement
cm³ - centimeters cubed (volume)
g - grams (mass)
Volume
Lenght x Width x Height = Volume
Volume Displacement method: put water into a graduated cylinder. record the measurement. place object inside the graduated cylinder. record the new measurement. original-new=volume
Ruler
Measure from the zero
Mass
use the balance
check if the pan is the correct one
clean the pan
zero the balance
mass the object
Change in mass
Mf (mass final)
-Mi (mass initial)
ΔM (change in mass)
Density
m=D
v
mass =Density
volume
Lab 1.4 (Sand)
Volume of sand alone=(sand+water)-water
Volume of air space= dry sand-sand alone
Fraction of sand that is air= airspace over dry sand
Percent of sand that is air= (airspace over dry sand) times 100
Sensitivity
ΔM = Sensitivity
# of yes'

(L x 100 x W x 100 x H x 100)
D=m
