Inference
Do you know that:
•
density has two labels g/mL and g/cm3?
•
general properties include weight, mass, volume and density?
•
specific properties include color, size, shape, texture, and hardness?
•
objects that sink in water have a density greater than that of water?
•
objects that float in water have a density less than that of water?
•
the mass of an object will never change unless matter is taken away from or added
to that matter?
•
Density’s formula is D = M/V?
•
To find volume, V = M/D?
•
To find mass, M = VxD?
•
inertia is an object’s resistance to change its motion?
•
the more mass an object has the more inertia it has?
•
you weigh less on the moon because the moon has less mass and therefore less
gravitational pull on you?
•
you can change an objects density if you change its volume? (think of a wadded
piece of tin foil verses a flat piece of the same size)
Can you:
•
explain why a small piece of steel sinks and a large steel ship floats?
•
solve simple density problems?
•
categorize given densities into those that will and will not float in water?
•
Fill in a chart like to following?
Mass of cylinder
32.7 g
Mass of cylinder and liquid
66.1 g
Mass of liquid
Volume of liquid
G
41.5 mL
Density of liquid
•
find the density of a liquid (not water) in a lab setting?
•
find the density of a rectangle in a lab setting?
