Bellwork How is mass and volume related to density? Bellwork How is mass and volume related to density? Density is the mass per unit volume Amount of mass packed into a certain volume Matter and Density - Review • What is matter? – Anything that has mass and takes up space • What is mass? – Amount of matter in an object • What is volume? – Amount of space an object takes up Let’s Demonstrate!! • We are going to use a graduated cylinder to measure the mass of a certain volume of water • Then we will plot the data ( mass vs. volume ) Plot the Data Density of Water • 1 g / mL !! Comparing Densities • Let’s drop stuff in our water!! • BLOOP!! • Why do certain things sink and other things not? Comparing Densities • Let’s drop stuff in our water!! • BLOOP!! • Why do certain things sink and other things not? • Some things are more dense than water • Others are less dense Oil & Water • When you mix • Which one is more dense than the other?
