1. Testing
Materials

2. Choosing materials for a building
What properties would it be useful to know
about the building materials?

3. Density, Mass
and Volume

4. Density

5. Which is heavier?

6. Which is more dense?

7. Working Out Volumes
Volumes of common objects:
• Cube – L3
• Cylinder – Lπr2
• Sphere – 4/3πr3

8. You are going to conduct a practical
Using the micrometers and mass balances
available, you will:
• Determine the volume and mass of the ball
bearings
• Plot these results onto a scatter graph
• Find the line of best fit
• Work out a gradient

9. Plotting the graph
• Mass on y-axis
• Volume on x-axis
• Fill as much of the paper as possible
• I am looking for neatness and accuracy
• Don’t overstate your precision when taking
readings!
