Mass vs. Weight
A measure of the amount of matter in an object.
Mass
A measure of how much space an object takes up.
Volume
A measure of how tightly packed the matter in an object is.
density
Materials that allow energy to flow through them easily.
Conductors
Turn on a flashlight
conduct
The force of gravity on an object.
Weight
What lab tool could you use to measure volume?
A graduated cylinder.
An object's ability to float.
buoyancy
Materials that do not readily permit energy to flow.
insulate
Step on a scale in a doctor's office.
weight
What unit of measurement is used to measure mass?
kilograms-kg
What is the formula you would use to calculate the volume of a solid?
Volume = length x width x height
V= L x W x H
Is a solid, liquid, or gas the least dense?
gas
The property of a material in which the particles line up pole to pole causing it to be attracted or repelled.
magnetic
A boat floats on water.
density
What unit of measurement is used to measure weight?
Newton- N
Besides using the formula, what is another way you could measure the volume of an object that does not have a regular shape.
Drop the object into a graduated cylinder filled with water and see how much water it displaces.
Why does a rock sink?
-Its density is more dense than the liquid's density.
- The rock weighs more than the water that it displaces.
Is a metal spoon a conductor or insulator?
conductor
Keep waters cold in a cooler.
insulate
Would you weigh more, less, or the same on the moon? Why?
You would weigh less because there is less gravity on the moon.
Calculate the volume of a fish tank that is 5 feet long, 2 feet high, and 4 feet wide.
40 ft3
Why does a boat float?
-It weighs less than the water that it displaces.
-It is mostly hollow inside
-It has a large surface area
Does a north and south pole on a magnet repel or attract?
A north and south attract. Two like poles will repel.
Use a compass to find your way.
