  1. Less dense More dense Density: 1599, from L. densus "thick, crowded.” -physical property of a substance that describes the degree of compactness of a substance

  2. Less dense More dense

  3. Less dense More dense

  4. Calculating density: Density = mass / volume D= m/v Find density of a ball of aluminum that has volume of 32.4 mL and mass of 87.48 grams. Find density of a ball of gold that has mass of 38.6 grams and volume of 2 mL. Which is more dense aluminum or gold?

  5. Stratify [strat-uh-fahy] verb : to form or place in layers; to lay in beds or layers

  6. SINK OR FLOAT? What pattern do you see for those objects that are less dense than water and those that have more density than water?

  7. 20 °C 15 °C Density is affected by temperature. Water density decreases as temperature increases and vice versa.

  8. Why does density matter?

  9. Liquid Layer Lab • Problem statement: How do the liquids layer? Why? • Pre-observations (sight, smell, squirt) • Hypothesis statement (if,then) • Materials • Procedure • Results (Use data table sheet) • Conclusion Demonstration

  10. Color Liquid Density (g/mL) Red Rubbing alcohol 0.78 Yellow Water 1.0 Green Saltwater 1.02 Blue Glycerin 1.2

  11. Problem: Do coke and diet coke have different densities? Will they differ in stratifying? Pre-observations: find mass and volume of each and calculate density. Hypothesis Materials Procedure Results Conclusion
