Reading a graduated cylinder
Density
density: mass per unit volume How heavy something is for its size
units: g/cm3 or g/mL 1 cm3 = 1 mL

Examples
1. Calculate the density of this block of wood!
2. Calculate the mass of this weight if the density is 8.00 g/cm3.
3. Calculate the volume of these pennies if the density of pennies is 7.07 g/cm3.
Make this table:

Calculate with your partnerShow your work!
1. The density of an object with mass of 10.0 g, and volume of 20.0 mL
2. The density of an object with mass of 10.0 g and volume of 5.00 cm3
3. Calculate the mass of a sample of matter with a volume of 10.0 cm3 and density of 2.0 g/cm3
4. Calculate the volume of a rock with mass 100.0 g and density 5.00 g/mL.
A: 20 September 2011
Grab a calculator Take Out Homework: Pre-test Objective: You will be able to:
make accurate measurements and use them to calculate density, mass and volume
Do now: Calculate the mass of a 20.0 cm3 block of wood with density 0.40 g/cm3. Show your work!
Agenda
I. Do nowII. Review: Estimating length and
volumeIII. Density stations!IV. Exit TicketHomework: Week 3 Homework #1-5Lab report due tomorrow!
Stations
With your lab group, visit each station (9 min. each)
Work quickly to determine what measurements you need to make, and record them (with units!) in your notebook.
Then, calculate the quantity specified on the poster. Include units!
In Your Notebook:
Quantities Calculations
Mass (g) =
Volume (cm3) =
Density (g/cm3) =
Station 1:
Expectations
Stay with your group and move on only when the timer gongs.
Begin working immediately. Use a reasonable, quiet professional
voice. Return all items to the station in an
organized way. Show all your work neatly!
Discuss
What makes something float or sink in water?
Why?
