Lesson 1.3: Measurements in Science

Metric System: *Copy this Table! The metric system is a universal system of measurement for science around the world. K H D * d c m Kilo Hecto Deka deci centi mili 103 102 101 1 10-1 10-2 10-3 (King Henry Died Drinking Chocolate Milk)

Metric Units: *Copy this Table! Measurement: Unit: Length meter (m)* Mass gram (g)* Volume Liters (L)* Temperature Celsius (oC)

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

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

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

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) 1.23456 123456 mm = __________ Hm

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
