1 GOALS OF SCIENCE I_________ and un__________ nature E_________ events in _________.Use ___________________ to make useful ___________________.
2 The 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____________
3 STATING 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
4 INFERENCESIn 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
5 FORMING 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?
6 DESIGNING 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
7 RECORDING & 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)
8 RECORDING & 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)
9 Graphing Graph A visual display of information or data Three main types_________ GRAPH
10 Line Graph Shows how data _____________________ or shows basic trends Plotting dataIndependent variable = __-axis (h________ or below)Dependent variable = ___-axis (along the ____ or vertical side)
11 Bar GraphCompares ___________ collected by ___________
12 Pie GraphShows how something is broken down into ________ or ______________
13 FORM 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?
14 Self 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
15 Self 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. _____________________
