1. Can you look at what Mr Porter has written in your book?? Do now!

2. This lesson Recall and use the relationship between density, mass and volume Density = mass/volumeD = m/V Describe how to determine density using direct measurements of mass and volume

4. Density

5. Remember that density is the mass of one cubic centimetre (or cubic metre) of a substance. So for example, gold has a density of 19.3 g/cm 3. This means one cubic centimetre (cm 3 ) of gold has a mass of 19.3 grams (or one cubic metre of gold has a mass of 19300 kg) http://www.youtube.com/watch?gl=IE&feature=related&hl=en- GB&v=14nahP_FVnM

6. Density (g/cm 3 ) = mass(g) volume(cm 3 ) Or using the formula triangle; m D x V kg/m 3 kg m3m3 Can you copy this please!

7. Density of regular shapes volume = length x width x height density = mass/volume mass using a scale length width height

8. Now measure the density of the materials on the trolley using the method described. Design your own table of results (using a pencil and ruler). Take some time to think about this! You have brass, Perspex, steel, copper, wood, aluminium and lead

9. Density of liquids Mass of liquid and cylinder Mass of cylinder Mass of liquid Density = mass/volume Volume

10. Density of irregular shapes (1) Difference in level gives the volume of the shape mass Density = mass/volume

11. Density of irregular shapes (2) Displacement can volume of object mass Density = mass/volume

12. Now measure the density of the liquids and objects on the trolley using the methods described. Design your own table of results (using a pencil and ruler). Take some time to think about this! You ethanol, cooking oil, water, acetone and mercury. Can you also then find the density of a “boss”

13. Homework Finish “Density” sheet. Due Thursday 9 th September.
