  1. Is It Matter Activity • Matter • Rocks • Baby powder • Milk • Air • Dust • Cells • Atoms • Smoke • Salt • Mars • Jupiter • Steam • Rotten apples • water • Not Matter • Light • Love • Fire • Heat • Sound waves • Gravity • Magnetic force • electricity Bacteria Oxygen Stars Dissolved sugar

  2. What is Matter • Matter is anything that has mass and takes up space. • It is the “stuff” that makes up everything in the universe. • Can be a solid, liquid or gas

  3. Matter Takes up Space • Volumeis the amount of space an object occupies or takes up. • Because matter has volume (takes up space), it cannot share the same space with something else at the same time!

  4. Measuring Volume • Volume of liquids: • Use a graduated cylinder • Units: liters (L) or milliliters (mL)

  5. Measuring Volume Volume of Solids: • Volume of a Normal Shaped Solid Object: • Use math! • Volume= length (l) x width (w) x height (h) • Volume of a Weird Shaped Solid Object • Put it in water! • Measure the change in water

  6. Practice with Volume! • What is the volume of this box? • What is the volume of this thing? h = 2 cm l = 5 cm w = 1 cm Volume = l x w x h 5 x 1 x 2 = 10 cm

  7. Matter Has Mass • Massis how much there is of an object • The heavier the object the greater its mass

  8. Difference Between mass and Weight • Mass = • The amount of matter in an object • Does not change with location • Weight = • The pull of gravity on an object • Changes depending on where you are

  9. Measuring Mass and Weight • Mass: • Use a triple beam balance • Units: gram (g), kilogram (kg), milligram (mg) • Weight: • Use a spring scale • Units: Newton (N)
