1GOALS OF SCIENCE I_________ and un__________ nature E_________ events in _________.Use ___________________ to make useful ___________________.
2The Scientific MethodThere are FIVE main steps to the scientific method:Stating the P_____________ (from an observation)Forming a H_______________ ( hint: ?)Setting up a _________ ____________R__________ and analyz____the resultsDrawing c____________
3STATING THE PROBLEMThis can be in the form of a question or statement.Implies that an observation has been made to lead to a question…Science is based on experimentation and observationObservations can be:Made directly with your sensesColorTasteShapeFeelSmell
4INFERENCESIn contrast to observations, which are things that we see or measure, inferences are c__________ based only on o___________The rule of inferring is to be __________ (makes sense).They are always tentative, meaning, they are not final explanations______ ______ __________ when new information is gained, or observations are made
5FORMING A HYPOTHESISA “t_________” statement, a possible explanation that explains known facts and predicts ________ ________.Should be written in the form“If... then…”Cause and EffectWhy? Or How?
6DESIGNING AN EXPERIMENT Must have several things:V______________E__________________ Group(s)receives all of the conditions of the experimentIndependent Variable – one thing that is changedDependent Variable – measures how the result respond to the independent variable (how it reacts…)C__________________ Groupreceives all of the conditions of the experiment. The Control group does not get the independent variable (changed condition)used as a means for comparison in the experimentCONSTANTS (things that ______ ______ change)Factors in the experiment that are maintained throughout the experiment, they ___________ the __________ throughoutPROCEDUREMust be clear and detailed
7RECORDING & ANALYZING DATA RECORDING DATANumerber data should be g_________ and/or tabledObservations should be written in clear, c_________ sentences.TWO TYPES OF DATAQualitative – descriptive; a behavior or appearanceQuantitative – numerical dataData TableIndependent variable (unit)Dependent variable (unit)
8RECORDING & ANALYZING DATA Attempt to figure out what the collected data means… why did it happen as it did?GraphTitle: Dependent variable vs. Independent variableD _________ variable (unit)I____________ variable (unit)
9Graphing Graph A visual display of information or data Three main types_________ GRAPH
10Line Graph Shows how data _____________________ or shows basic trends Plotting dataIndependent variable = __-axis (h________ or below)Dependent variable = ___-axis (along the ____ or vertical side)
11Bar GraphCompares ___________ collected by ___________
12Pie GraphShows how something is broken down into ________ or ______________
13FORM CONCLUSIONSBe sure to draw conclusions based ____________________.Make inferences based on _____ ______ and the new knowledge gained in the experiment._____ ______ restate the procedure or simply restate the results…How do the results compare to your hypothesis?How can this data be used further?What other tests could be done?
14Self Assesment1) Directions: Place the Scientific Method Steps in the right order. Use the numbers 1 through 5 to show which steps come firstRecording and Analyzing Results (Graphs)Design a controlled Experiment (Variables)Stating the Problem (from an observation)ConclusionForm a Hypothesis
15Self Assessment cont. Designing an Experiment: What is a controlled group?How is the controlled group different from the experimental group?List one thing that you DO NOT do in the conclusion. _____________________
