### Density

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

7. 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. 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…
