1. Happy Monday! Please pick-up your name plate from the front table & put it on the corner of your desk. Have out your science composition notebook.

2. How does the precision of the equipment affect the accuracy of the measurement when calculating density?

3. Density Equation Density (D) = mass (m) volume (v)

4. density Using the equipment at your lab table find the density (g/cm 3 or g/mL) of: - the block - the marble - water While collecting data be thinking about: -the hypothesis -the procedure -the IV, DV, constants, etc.

5. Design an experiment that answers the following question, and uses the data we collected in today’s lab… How does the precision of the equipment affect the accuracy of the measurement when calculating density?
