1Standard I, Objective 1- Part 3: The Metric System SCIENCE AHSGEStandard I, Objective 1- Part 3: The Metric System
2The Metric System System of measurement based on units of 10 Also known as- System International (SI)Used by scientists worldwideAllows for sharing info
3DistanceMeter- base unit for distance measured with a ruler, meter stick, tape measure, etc.Length:Circumference- around circleDiameter- across circleRadius- ½ across a circlePerimeter- around a spaceWidth:ThicknessHeight:Tall, short, longArea: A = L x W ( _m2)
4Mass or WeightGram- base unit for mass/weight measured with a scale or balanceMass- Amount of matter in an objectNever changesWeight- Measure of gravity pulling downward on an objectChanges with gravity
5Volume Liter- base unit for volume measured with a graduated cylinder Measures liquid volumeMeniscus- Curvature in top of liquidCaused by adhesion of water to sides of cylinderVolume- amount of space an object takes upCapacityUse Fluid Displacement for irregular solid (sides not measurable)Put known amount of liquid in grad. cyl.Drop in objectDetermine difference of volumeUse V = L x W x H ( _m3) for regular sides (measurable sides)Use a ruler/meter stick, etc.
