Density Lab – Part 2Purpose: Finding density of water, a medicine bottle and a rock

You will need to write a Lab Report on this. I suggest you pay attention to what you’re doing. If you have a question, I am happy to help. But I do require that you listen to all instructions. 1st Consequences: Doing lab alone.2nd Consequence: Doing an alternate assignment.

• To find density of WATER...• FIRST: You will need to find mass. • You will use the triple beam balance. • Measure the container, add the water, measure again

and SUBTRACT • SECOND: You will need to find volume. • Easy! Use the same amount of water you had of the

triple beam balance, record level in graduated cylinder• THIRD: Density – you know how to do this!

Density Lab – Part 2• To find density of ROCK…• FIRST: You will need to find mass. • You will use the triple beam balance. • Easy! Calibrate, put the rock on the balance, measure!• SECOND: You will need to find volume. • Be CAREFUL!!!!• Measure a volume of liquid. Add rock. Measure again.

Subtract!• THIRD: Density – you know how to do this!

• To find density of BOTTLE….• FIRST: You will need to find mass. • You will use the triple beam balance. • Easy! Calibrate, put the rock on the balance,

measure!• SECOND: You will need to find volume. • Measure a volume of liquid. Add bottle, submerge.

Measure again. Subtract!• THIRD: Density – you know how to do this!
