Density

You know, just a general measure of how much "stuff" is in there, very technical...

Open Ended

Not knowing technically what density is yet, what does your gut tell you? Which is "more dense", the balloon of air or the bowling ball? What makes you think that?

Type response here

Particle Diagrams and Density

We can imagine the "stuff" as particles and recognize that both the amount of particles (mass) and the space they occupy determine the density
Let's compare and discuss A and B...
Now let's compare and discuss A and C...

Calculating Density

This is in the Edpuzzle video for the week and the Notes so make sure you get it down!
mass is typically in units of g or kg
volume of liquids is in mL
volume of liquids is in cm³
density has a "combined" unit of g/mL or g/cm³

Practice calculating density

Multiple Choice

A block of aluminum occupies a volume of 15.0 mL and weighs 45.0 g. What is its density?

3 g/mL

0.3333 g/mL

675 g/mL

I have no idea

Multiple Choice

A sample of liquid has a mass of 300 g and occupies 50 mL in a graduated cylinder. What is the density?

15,000 g/mL

.16667 g/mL

6 g/mL

Yup, still no clue

Poll

How are you feeling about your ability to apply the density formula to calculate density?

This is pretty easy for me

As long as I have the formula in front of me I think I'll be alright

Numbers and math scare me so I have no confidence even if I'm doing it right

I can't follow what we're doing so I should probably watch the Edpuzzle and Notes and maybe come for extra help
