1An organized way of studying things and finding answers to questions. SCIENCEAn organized way of studying things and finding answers to questions.
2TYPES OF SCIENCEEach type of science is given a name to describe what is being studied.
3TYPES OF SCIENCE Life science Physical science Earth science Space scienceStudies plants, animals, and other living thingsStudies energy, matter, and chemistryStudies the processes that shape the EarthThe study of all things in the universe
5Organized method used to solve problems and answer questions EXPERIMENTAL DESIGNOrganized method used to solve problems and answer questions
6STATE THE PROBLEM Ask a question What are you trying to solve? Which color Life Saver dissolves the fastest?
7GATHER INFORMATION Think about your own experiences with this topic Do researchWho else studied this and what did they find outIt has been my experience that I eat the green Life Savers faster than any other color
8FORM A HYPOTHESIS Pose a testable explanation. What do you think is going to happen?Make an educated guessI think the green Life Saver will dissolve faster than any other color.I also think that purple will last the longest.
9DESIGN AND PERFORM AN EXPERIMENT A set of steps to follow to test the hypothesisObserve and record all informationBe sure to identify the controls, constants, and variables1. give each test subject a different color Life Saver2. each test subject puts the Life Saver in their mouths at the same time3. record the time it takes for the candy to dissolve
10CONTROLS AND CONSTANTS The standard to which the outcome of a test is comparedWhat you measure againstCONSTANTSThe things that remain the same
11VARIABLES Something in an experiment that is changed or measured The color of Life Savers was changedThe time to dissolve was measured
12VARIABLES INDEPENDENT VARIABLE What is changed or different What starts the experimentCan only be 1DEPENDENT VARIABLEWhat is measuredThe result
13EXTRANEOUS VARIABLES Unexpected or unpredictable events Improperly controlled experimentEX: the Life Saver lab
14ANALYZE THE DATA Determine what the data means Make graphs and data tables
15DRAW A CONCLUSIONA logical answer to a question based on data and observationsMy data does not support my hypothesis, I said the green Life Saver would dissolve the fastest but the white one did.The purple Life Saver did last the longest.
16If the hypothesis is supported The experiment needs to be repeated several more timesThe results need to be shared with the scientific community
17If the hypothesis is not supported The results need to be shared with the scientific communityThe hypothesis needs to be revised and tested again
