Metrics and Measurements AIM: To be able to accurately measure and record data

The Metric System

Prefixes Kilo means 1000. Hecto means 100. Deka means 10. Unit: means 1. (Meter, Gram, or Liter) Deci means 0.1 Centi means 0.01 Milli means 0.001

Matter Matter is anything that has mass and volume.

Inertia The ability of an object to want to resist movement.

Gravity The force of attraction between objects due to their mass.

Weight The effect of gravity on an object.

Mass Mass is defined by the amount of matter or the number of atoms an object has. Mass is measured by a triple beam balance Mass is measured by the unit grams

How to use a balance scale properly Carry scale with one hand on the bottom & one holding center arm. Zero out the scale so that the pointer is even with zero. Make sure you hear a click when moving riders and add up all riders. Be sure to return all weights back to zero when done measuring.

Measure the mass of this object being measured on a balance scale. 514.0 grams

Determine the mass of this object being measured on a balance scale to the nearest tenth. 153.7 grams

The little lines are millimeters Length, Width, Height Length measures how long an object is Width measures how short or wide an object is Height measures how tall an object is Tool of measurement is a ruler All three are measured by the unit meters The little lines are millimeters

There are 10 mm in 1 cm. What is the length of the worm in cm? What is the length of section A in mm?

48.0 cm3 = 8.0 x 2.0 x 3.0 Measure length, width, & height. Multiply. V = l x w x h (cm3) 48.0 cm3 = 8.0 x 2.0 x 3.0 W = 2 cm H = 3 cm L = 8 cm

Area Area is a measure of how much surface an object has Equation: length x width Units: cm2 , m2 , km2
