Finding Mass Using a Triple Beam Balance

Today we did an activity called Mix and Match Mass to learn how to use a triple beam balance. After making predictions about the mass of the items they have been working with over the past week, students found the actual mass of the items.
Homework: First, use the handout below from the Day 1 of Volume by Displacement. Use the volume you found for four of your objects and use the mass you found from today's activity, to find the density of each object.

For Example: If you found the volume of Rock #22 to be 30mL and the mass of Rock #22 to be 10g, the density would be 0.33g/mL.
