With your table, list as many units of measurement as you in the time given. • Select a recorder to write answers in their science notebook. • Number your answers • The most correct answers will win.
What categories can be assigned to the units we identified?
Time Distance Temperature Volume Mass Electric Current Intesity of Light
Units of Measurement Visual We need 5 people to make category signs: • Time • Distance Volume • Temperature • Volume • Mass Everyone else will help create clear, legible labels for examples of each category. Please fill the space on the paper given. Kilogram Ounce Milliliter
When finished: Category Signs: Tape at the top of the closet door. Examples: Tape under categories in size order smallest at the top of the door, largest measurments near the bottom of the door. Volume Milliliter Ounce Gallon
SI Base Units: (SNB p. 2) Meter for distance Kilogram for mass Second for time Mole for amount of substance (We’ll use Liters) Kelvin for temperature (We’ll use Celsius) Newton force Pascal for pressure Joule for energy
Let’s highlight the base units we identified: Time Distance Temperature Volume Electric Intensity Current of Light Volunteers: Can someone highligh base units we have labeled? Can someone make signs for base units we have missed?
Which labels have we identified that are NOT SI units? Options: Create a category of non-SI units, and table somewhere else OR Put a line through the non-SI unit labels.
