Measurement 2010

  1. 1. Warm Up<br />1. What is the difference between QUANTITATIVE data and QUALITATIVE data?<br />2. What are some examples of<br />QUANTITATIVE data?<br />
  2. 2. Homework Review:<br />You pour yourself a glass of orange juice. When you take a drink, it is warm.<br />Figure out what is wrong. Use the following steps of the scientific method:<br />Observation, Question, Hypothesis, Experiment, Conclusion<br />
  3. 3. Measurement<br />Gathering QUANTITATIVE data<br />
  4. 4. Mass<br />Triple Beam Balance<br />
  5. 5. Online Practice<br />Let’s practice with the link online!<br />
  6. 6. What is the mass below?<br />
  7. 7. What is the mass below?<br />
  8. 8. Quick…<br />Turn to your neighbor and share the things that you wrote down under the information section for finding mass!<br />
  9. 9. Now,<br />In your group, <br />complete the<br />"Measuring Mass"<br />activity<br />
  10. 10. Warm-Up<br />How is mass measured (what is the tool and the unit?)<br />Explain the steps for measuring mass.<br />
  11. 11. Quick Check<br />What is this tool called?<br />What are the parts called at each of the letters?<br />C.<br />D.<br />B.<br />A.<br />
  12. 12. Quick Check cont’d.<br />Explain how you use the tool in question 1 to find mass.<br />What unit did we use to measure mass?<br />
  13. 13. Volume<br />Today we will measure volume. There are several ways to do this.<br />
  14. 14. 1. Liquid volumes<br />To measure the volume of a liquid, pour the liquid in a graduated cylinder and read the volume…at the bottom of the meniscus<br />
  15. 15. Liquid volumes<br />Practice…<br />
  16. 16. 2. Volume of a regular solid<br />For anything cubic, use the formula below:<br />Volume = L x W x H<br />8cm<br />5cm<br />10cm<br />**using a ruler, the volume of a cube is measures in cm3<br />**1cm3 = 1ml<br />
  17. 17. 3. Volume of an irregular solid<br />Use the water displacement method<br />Drop the solid into a liquid and measure how much the liquid rises or how much spills out of the can<br /> Volume of water + Solid<br />-Volume of water<br /> Volume of solid<br /><ul><li>Try this:</li></ul>A rock dropped into 25ml of water <br />causes the water to rise to 29ml. <br />What is the volume<br />of the rock?<br />
  18. 18. Quick…<br />Turn to your neighbor and share the things that you wrote down under the information section for each method of finding volume!<br />
  19. 19. Now,<br />In your group, <br />complete the<br />"Measuring Volume"<br />activity<br />
  20. 20. Super ball<br />Soda<br />Blue laundry detergent<br />Green liquid<br />Marble<br />Rock<br />Wooden block<br />Free reading book<br />Toy Car<br />
  21. 21. Warm-Up<br />How do we find the volume of a regular solid like a block?<br />What is the relationship between 1 cm3 and 1 ml?<br />
  22. 22. Super ball<br />Soda<br />Blue laundry detergent<br />Green liquid<br />Marble<br />Rock<br />Wooden block<br />Free reading book<br />Toy Car<br />
  23. 23. B.<br />A.<br />D.<br />C.<br />
  24. 24. Warm-Up<br />Describe in detail how you would go about finding the volume of a rock!<br />
  25. 25. Common lab errors to avoid:<br />Use units for data<br />Read the question carefully; make sure your answer responds to the question<br />Use details and supporting facts<br />Write in complete sentences<br />
  26. 26. Measurement; Mass and Volume<br />Use the words associated with mass and volume to create a word web or concept map to show how they are related. Some words are provided for you, but you may add words. YOU MUST use at least the words provided. <br />Measurement Mass<br />Volume Balance<br />Graduated cylinder Liquid<br />Overflow can Solid<br />Meniscus Grams<br />Cube/Solid Milliliters<br />Water displacement<br />
  27. 27. Warm-Up<br />What is that piece of glassware called?<br />What is that piece of glassware called?<br />What is that piece of equipment called?<br />
  28. 28. Warm-Up<br />What is 1 important thing you learned about measuring?<br />What is 1 question you still have about measuring?<br />
