Mr. Sumner's Science
100
It is the formula to calculate density.
What is D = M/V?
100
Anything that has mass and volume.
What is matter?
100
The metal ball didn't fit through the ring after we heated it because of this.
What is expansion?
100
The average molecular motion of an object.
What is temperature?
100
Conductivity, hardness, odor, and the ability to dissolve are called this.
What are physical properties?
200
It is the density when you have a mass of 10 grams and a volume of 2 cubic centimeters.
What is 5 g/cm3?
200
How much material is in an object.
What is mass?
200
Diffusion of food coloring happens faster in warm water because the water molecules are doing this.
What is moving faster?
200
The total molecular motion of a substance.
What is heat?
200
This is what we call it if particles could stop moving, having no heat at all.
What is absolute zero?
300
It is the units we used in class for density.
What is grams per cubic centimeter?
300
Scientific units for weight.
What are newtons?
300
Engineers have to consider expansion and contraction because otherwise their materials might do this.
What is crack or buckle?
300
The amount of heat in a substance.
What is heat energy?
300
It is a non-digital scale with 3 bars that have weights that slide back and forth to find mass.
What is a triple beam balance?
400
It is the density of water.
What is 1 g/cm3?
400
This is how you find the volume of a cube.
What is length times width times height or length cubed?
400
Liquids and gases do this, but not solids.
What is diffuse?
400
Getting burned when you touch a hot stove is an example of this.
What is heat transfer?
400
This is a way to find the small masses of gases.
What is measure different pressures in a container?
500
A rock with a density of 4 g/cm3 would do what when placed in a liquid with a density of 0.5 g/cm3?
What is sink?
500
A method of finding the volume of an irregular solid.
What is the water displacement method?
500
This false example for "expansion" is due to a change in the state of matter rather than molecules moving faster.
What is water freezing?
500
An iceberg has more heat energy than a pot of boiling water because it has more of this.
What is mass?
500
This is what percent of your final grade comes from tests.
What is 60%?
