  1. Aim:#20 Gummy Bear Lab. • Density is a comparison of how much matter there is in a certain amount of space.

  2. Difference Between Mass and Weight • Mass is a measure of how much matter an object has.

  3. Difference Between Mass and Weight • Weight is a measure of how strongly gravity pulls on that matter.

  4. Huh!!!!! • Thus if you were to travel to the moon your weight would change because the pull of gravity is weaker there than on Earth but, your mass would stay the same because you are still made up of the same amount of matter.

  5. Which one is more dense? • How about this: Which square is more dense?

  6. Which one is more dense? • Now which one is more dense?

  7. What is density? • Density = mass OR mass ÷ volume. volume • Units for density: g . cm3 • Why are these the units for density? • Department of Motor Vehicles? Or the “Broken Heart Formula” ALWAYS REMEMBER UNITS!

  8. Let’s try a density problem together • Sean has a paper clip. It has a mass of 9g and a volume of 3cm3. What is its density? • Alexa also has an eraser. It has a mass of 3g, and a volume of 1cm3. What is its density?

  9. Work on these problems with your neighbor. • Sophia has a rock. The rock has a mass of 6g and a volume of 3cm3. What is the density of the rock? • Anthony has a gel pen. The gel pen has a mass of 8g and a volume of 2cm3. What is the density of the gel pen?

  10. Super Scientist Question of the Day • Phineas has a book, a ruler, and a balance. • How can Phineas find the density of the book with the tools he has?
