  1. Measurement Review

  2. Measurement Review All investigations require some type of measurement.

  3. Measurement Review All investigations require some type of measurement. What are some examples?

  4. Measurement Review All investigations require some type of measurement. What are some examples?

  5. Measurement Review All measurements can be divided into two types: • Qualitative

  6. Measurement Review All measurements can be divided into two types: • Qualitative-this is an approximate measure. An example would be it is REALLY heavy

  7. Measurement Review All measurements can be divided into two types: • Qualitative-this is an approximate measure. An example would be it is REALLY heavy • Quantitative- states a specific quantity or amount. For example, it has a mass of 15.90 kilograms

  8. Measurement Review What is the big deal with the metric system?

  9. Measurement Review What is the big deal with the metric system? Why is it better than the English system?

  10. Measurement Review What is the big deal with the metric system? Why is it better than the English system? Convenience and Adaptability

  11. Measurement Review Convert 5 miles to inches

  12. Measurement Review Convert 5 miles to inches 5 miles X 5,280 feet X 12 inches =316800

  13. Measurement Review Convert 5 miles to inches 5 miles X 5,280 feet X 12 inches =316800 Convert 5 kilometers to millimeters

  14. Measurement Review Convert 5 miles to inches 5 miles X 5,280 feet/miles X 12 inches/foot =316800 inches Convert 5 kilometers to millimeters 5 kilograms = 5,000,000 millimeters

  15. Measurement Review What do you do if you require a measurement that is less than 1 inch? 1 once?

  16. Measurement Review What do you do if you require a measurement that is less than 1 inch? 1 once? Fractions

  17. Measurement Review

  18. Measurement Review In the metric system, all base quantities use the same prefixes to denote magnitude. Base Units: Grams-mass

  19. Measurement Review In the metric system, all base quantities use the same prefixes to denote magnitude. Base Units: Grams-mass Meters-length

  20. Measurement Review In the metric system, all base quantities use the same prefixes to denote magnitude. Base Units: Grams-mass Meters-length Liters-volume

  21. Measurement Review Metric Prefixes Kilo hectodeka I decicentimilli Meter Liter Gram

  22. Measurement Review What about units smaller than a milli and larger than a kilo?

  23. Measurement Review Giga Nano

  24. Tools There are many instruments which aid in scientific investigation. 1) The microscope

  25. Tools There are many instruments which aid in scientific investigation. 1) The microscope allows images to be magnified. There are two main types: • The Light Microscope

  26. Tools There are many instruments which aid in scientific investigation. 1) The microscope allows images to be magnified. There are two main types: • The Light Microscope • The Electron Microscope

  27. Tools Light Microscope Image

  28. Tools • Light Microscope typically measures at the level of a micrometer • Can be used to observe living organisms • Uses light for illumination

  29. Tools Electron Microscope Image

  30. Tools • Electron Microscope measures at the level of the nanometer • Only dead organism can be viewed • Uses electrons for illumination

  31. Tools Centrifuge is used to separate parts of a cell in a technique known as cell fractionation.

  32. Tools Centrifuge is used to separate parts of a cell in a technique known as cell fractionation. 1) Cells are broken up by a blender

  33. Tools Centrifuge is used to separate parts of a cell in a technique known as cell fractionation. 1) Cells are broken up by a blender 2) Spun at 20,000 times per minute causing organelles to separate based on density and size.
