1
On a slope of Mass vs. Volume, Denisty is the:
maximum
y-intercept
slope
minimum
2
Classifications should be made based on:
inferences
hypotheses
observations
interpretations
3
Which measurement can be made with only human senses?
ripping paper into 1-inch squares
adding 5 grams of sugar into coffee
counting 52 playing cards
measuring temperature
4
Volume: 2 mL Mass: 10g What is the density?
20 mL
5 g/mL
20 g/mL
5g
5
Which statement is an inference?
The rock is black
The rock is dense
The rock must have cooled quickly
The rock has a chunky texture
6
Ice floats in water because:
ice is less dense
ice is more dense
ice has more mass
ice has less mass
7
Volume 5 mL Density 5 g/mL What is the mass?
25g
10g
1 g/ml
25 g/mL
8
If you heat a substance,
mass and volume increase
mass is constant, volume increases
mass and volume decrease
mass increases, volume is constant
9
If you cut a rock in half, its density will change
True
False
10
Mass = Volume × Density
False
True
11
I did not lose the reference table Ms. G kindly gave to me.
False
True
12
Classification is used to:
organize observations
extend observations
make accurate inferences
form hypotheses
13
A graduated cylinder is used to find the volume of a cube.
True
False
14
How do you find the average?
Find the halfway point between the smallest and largest value
Add it all up, divide by the largest value
Add it all up, divide by the total # of measurements
Estimate
15
Your reference table can help you convert Farenheit to Celsius without math.
True
False
16
Which equipment is used to measure mass?
balance
graduated cylinder
spirometer
thermometer
17
If Length: 1 cm, Width: 2 cm, and Height: 3 cm- what is the volume?
6 cm
5 cm3
6 cm3
5 cm
18
Rate of change = change in value ÷ time
False
True
19
Volume =
mass / density
density / mass
density × mass
density - mass
20
Density =
volume + mass
volume ÷ mass
mass ÷ volume
mass × volume
