This is a quiet activity.Read the question.THINK of the answer.Never yell out your answer.Chapters 1-4Vocabulary Review1Way of learning about the natural world.science2A possible answer to a scientific question.hypothesis3The one variable that is purposely changed to test a hypothesis.independent variables4An experiment in which only one variable is changed at a time.controlledexperiment5The facts, figures, and other evidence gathered through qualitative and quantitative observations.A picture of your data that allows you to visually analyze and compare information

data6Type of observation that uses numbers, measurements or amounts.quantitativeobservation7Type of observation that gives a description. May involve taste, texture, shape or color.qualitativeobservation8A system of units used by scientists to measure the properties of matter.International Systems of Units

9a measure of the amount of matter in an object mass

10A measure of the force of gravity acting on an object.weight

11The amount of space an object or substance takes up.volume

12________ is a measure of the mass of a material in a given volumeDensity

13Data that does not fit with the rest of a data setAnomalous data14A representation of a simple or complex object or processmodel15Line graph where the data points form a straight lineLinear graph16A line graph in which the data points do not fall along a straight lineNonlinear graph17Name the vocabulary word.Anything that has mass and takes up spacematter

18The study of matter and how matter changeschemistry

19 Each type of ____ is unique because it has its own number of protons, neutrons and electrons a substance that cannot be broken down into any other substances by chemical or physical means Element

20The basic particle from which all elements are madeAtom

21A group of two or more atoms held together by a chemical bond.molecule

22Matter Vocabulary- Chapter 3Physical properties of a substance changeThe identity of the substance does NOT changePhysical change

23Matter Vocabulary- Chapter 3 change in the identity of a substance due to the chemical properties of that substanceExample: firewood becomes ash because it reacts with oxygen in the airChemical change

24Matter Vocabulary- Chapter 3 states that matter of what you end with is always the same as the mass of what you started withmatter is not created or destroyed in any chemical or physical changeAntoine Lavoisier came up with this over 200 years agoLaw of Conservation of Mass
