Simple Density
What are the two values that form the RELATIONSHIP we know as density?
Mass and Volume
If the mass of an object is 55g and the volume is 5cm3, what is the density?
D = 11 g/cm3
What do we call the section of a scientific report that has tables and graphs?
Data section
What is the formula we use to calculate Density?
D = M/V
An object has a mass of 126.72g and you figure the volume by displacing 81.3mL of water. What is the density? Would it float or sink?
D = 1.558 g/cm3
It would sink.
After posing a question, what is the next step?
Do some research
When calculating the volume of a solid or liquid, what are the 2 units we might see?
Cm3 and mL
What is the mass of an object that has a volume of 38.1 cm3 and a Density of 2.5 g/cm3?
M = 95.25 g
Hypothesis
When using the formula for density, what are we actually doing mathematically with the mass and volume values?
Divide the MASS by the VOLUME
What is the volume of an object that has the density of 5.57 g/cm3 and a mass of 49.6 g?
V = 8.90 cm3
Describe what an independent variable is.
The change you manipulate in an experiment.
If we are given the MASS and the DENSITY, and asked to calculate the VOLUME, what do we do?
Use the same formula (D=M/V), plug in the values you are given, and solve!
Calculate the density if the mass is 0.0465 kg and the volume is 0.36 m3 (hint: use King Henry slide to first convert these units into g and cm3)
46.5 g and 36 cm3
D = 1.29
This is a numbered series of steps you will take to test your hypothesis.
