  1. Measuring Length & Mass By: Brianna Shields September 13, 2005

  2. DO NOW • 1. What tool is used to measure length? • 2. What tool is used to measure mass? • 3. What tool is used to measure temperature?

  3. Definition Distance between two points Length

  4. Tool Ruler or meterstick Length

  5. Label units Centimeter (cm) Length

  6. Tips Line object up at zero mark Measure with decimals (no fractions) Be accurate Label your answer Length

  7. Example • What is the length of the object at left?

  8. Example • What is the length of the object at left?

  9. What is the length of the object at left? Example

  10. Definition Amount of matter in an object Mass

  11. Tool Triple beam balance Mass

  12. Label units Grams (g) Mass

  13. Using a tbb 1. Zero the balance (all masses left)

  14. Using a tbb 2. Move 100 g mass first- until balance tips, then slide mass one spot left

  15. Using a tbb 3. Move 10 g mass next until balance tips, then slide mass one spot left

  16. Using a tbb 4. Move 1 g mass last until balance tips, then slide mass one spot left

  17. Using a tbb 5. Add up all three masses to find the total mass

  18. Tips Be accurate Use decimals, no fractions Label your answer correctly Mass

  19. Example • What is the mass of the object to the left?

  20. Example • What is the mass of the object to the left?

  21. Practice • Work with your lab partner • Complete the length and mass practice questions in your handout • We will go over the correct answers at the end of the period
