2. Measurements: Learning Objectives
How to make a perfect Data Table
How to Make a perfect Line Graph
How to accurately measure: Length, Weight, Volume
Vocabulary to Know: Mass, Displacement, Meniscus

3. Measurements for Labs/Projects
Perfect Data Tables Have:
-Titles
-labels for every set of variables…
-with units (ex: meter, cm, sec, liters, )
- all categories filled in as much as possible

Perfect Graphs Have:
ALL Data points correctly placed & evenly spaced
Make sure all data series are labeled with a Key (if needed)
Decide on an appropriate graph style (line, bar, or pie graphs)

9. Using Graphs to support your ideas

10. Using Graphs to support your ideas

11. Units = Meter (m), Kilometer (km), Centimeter (cm)
Measurements
Length : a measured distance between 2 points
Units = Meter (m), Kilometer (km), Centimeter (cm)

12. Mass: a measure of the amount of matter in an object
Weight: the mass of an object multiplied by the acceleration of the gravity
Weight = mass x gravity
The same unit (grams/kilograms) are used for both mass & weight and for our use/purpose they mean the same thing, just be aware they are not same
Pg 25 & King Henry WS

13. Volume: how much space an object takes up in 3D.
Units = (same as for liquids)
Liters (L) or Milliliters (ml)

14. Displacement: measuring Volume by putting a sinking object into a known amount of water (best when formulas don’t work)
Meniscus: Greek word meaning crescent; a curve in the surface of a liquid
