Transcript

  • 1. Density of Metals Aim To be able to calculate the density of a metal by measuring the volume and mass.
  • 2. Risk Assessment Risk: Hazard: Control Measure:
  • 3. Equipment Diagram
  • 4. Method
    • Find a flat place to work near a sink.
    • Use the balance and record the mass of the block (g).
    • Fill a Eureka can with water.
    • Put a graduated cylinder below the spout of the Eureka can.
    • Put the block in the Eureka can. Try not to spill or splash and water.
    • Measure the water in the graduated cylinder.
    • Calculate the volume of the block.
    • Calculate the density of the block. Repeat this procedure 2 more times.
    • Repeat steps 1-9 for the other blocks.
  • 5. Method: measuring mass and volume
    • Take the mass of the block (g) using a scale and recode it in a table.
    • Fill a Eureka can with water and let it empty out until it stops dripping.
    • Put the block into the Eureka can and catch the displaced water using a measuring cylinder.
    • Record the volume of displaced water (ml).
    • Calculate the density of the block by dividing mass by volume
    • Repeat the test 2 more times for this block.
    • Repeat steps 1-6 for the other blocks.

  • 7. Analysis Density is… The formula for density is… The most dense block was… This is because the particles are… A diagram to show this is… The least dense block was… This is because the particles are… A diagram to show this is…
  • 8. Evaluation My experiment went… I did not have problems with… because… I had problems with … because… To improve my experiment I could… My results would be more reliable if I… I liked this experiment because… I disliked this experiment because…
