Measuring volume with accuracy

This task is about measuring accuracy of equipment.

In groups of 3:

  1. Weigh each cylinder/beaker and write this in the table provided (column 2).
  2. Measure 100 mL of cold water into each piece of equipment.
  3. Weigh the piece of equipment with the water in it, and fill in columns 3,4 and 5.
  4. Repeat steps 1-3 four more times.
  5. Plot results from column 5 onto the scatter graph.
  6. Discuss the patterns with your group, then answer the two questions, c)i) and ii).
NOTE: 1mL of water weighs 1g
