1 anything that takes up space and has mass What is matter?anything that takes up space and has massmatter is made of atomsmass – the amount of matter in an objectIf the object has even one atom it has a very tiny mass. If it has a lot of atoms, it has a larger mass.
6 In science, however, we use the metric system! Only one country in the world doesn’t use the metric system as it’s national system of measurement:The United States of AmericaWe use the English System as our national system of measurementIn science, however, we use the metric system!
7 The metric system was created in France It is also calledSysteme International d’Unitesor the International System of UnitsUnits of the metric system are called SI Units
8 How is matter measured?length – the distance from one point to anotherEnglish units: inches, feet, yards, milesSI base unit: meter (m)volume – the amount of space an object takes upEnglish units: teaspoon, cup, pint, quart, gallonSI base unit: liter (L) *capitalmass – the amount of matter in an objectEnglish units: ounces, pounds, tonsSI base unit: gram (g)
9 Metric Conversion Stair Step Method If you move down, the number gets bigger (multiplied). Move the decimal to the right.kilo- (k) 1,000hecto- (h) 100deka- (da) 10BASE lengthmeter (m) volumeLiter (L) mass gram (g)deci- (d) .1 or 1/10If you move up, the number gets smaller (divided). Move the decimal to the left.centi- (c) or 1/100milli- (m) or 1/1000
10 mass vs. weight mass is the amount of matter in an object weight is a measure of the force of gravity acting on an objectDo you weigh the same on the earth and the moon?
