Poll

How are you feeling about density and calculating density?

• I am rocking density!

• I feel pretty good about density.

• I still have questions.

• Density, what is that?

Density

• Reminders:

  Density= Mass ÷ Volume

  Volume of a Regular shaped object= length x width x height

  Volume of an Irregular shaped object= Volume of water and solid

  Minus Volume of water

Density Units

• ALWAYS PUT YOUR UNITS WITH YOUR ANSWER

  Mass is in grams (g)

  Volume is in milliliters (mL) or Cubic centimeters (cm3)

  Density is in g/cm3 or g/mL
