Measurement:
Unit:
Length
meter (m)*
Mass
gram (g)*
Volume
Liters (L)*
Temperature
Celsius (oC)

4. Tools: There are many tools scientists use to collect data Ruler Timer
Triple-Beam Balance (Scale)

5. Scientific Notation:
Easier way to deal with extremely large and extremely small numbers
Convert by moving the decimal left or right
Parts of a Number

6. Metric Conversion Ladder Method:
*Copy Chart if you want, but it will be on your worksheet

7. Metric Conversion Example:
Start mm = End Hm
End
Five steps to the left = 5 steps for decimal point to the left
Kilo
(Km)
Hecto
(Hm)
Deka
(Dm) U
(m)
Start
Deci
(dm)
Centi
(cm)
Milli
“Point” to the left
(mm)
mm = __________ Hm

8. Important Equations:
Area of a block = Length x width (cm) Volume of a block = Length x width x height (cm3) Volume of a liquid= Total volume (after object is added) – Original volume (before object was added) (mL) Density = Mass/Volume Temperature conversions: °C = (°F – 32°) / 1.8
