2 The Scientific Method Problem Research Hypothesis Materials Procedure ResultsConclusion
3 Problem To receive full credit for this section, the problem should be correctly statedand the experiment to be performedwill be apparent.Using our example experiment comparing the effectiveness of styrofoam, plastic, glass, and paper in keeping water cold, the problem should be stated like this:Which material will keep water coldest? Let’s find out by recording the temperature of water in styrofoam, plastic, glass, and paper cups.
4 ResearchTo receive full credit for this section, your research should be highly relevant and summarized in your own words.Use at least two reference sources. Be prepared to site them, if asked.Write at least ten sentencesUse your own wordsMake sure your sentences are relevant and on topicWrite factual information, not narrative or opinion
5 HypothesisTo receive full credit for this section, the hypothesis should be supported by an explanation citing research.Using our example experiment comparing the effectiveness of styrofoam, plastic, glass, and paper in keeping water cold, the hypothesis might be stated something like this:Based on my research on insulators, the styrofoam will keep the water cold most effectively because a styrofoam type material is a common component in commercially made insulation.
6 MaterialsTo receive full credit for this section, you should provide a comprehensive list of materials in an easy to follow numbered list.Using our example experiment comparing the effectiveness of styrofoam, plastic, glass, and paper in keeping water cold, the materials list might look something like this:4 cups of cold water12 ice cubesstopwatch or timer4 cups – styrofoam, plastic, glass, paper4 thermometersrecord sheet
7 VariablesVariables are what affect an experiment. There are three types of variables that you will see in your experiment:Independent variable – the variable that is purposely changed (styrofoam, plastic, glass, paper)Dependent variable – the variable that is observed that may change in response to the independent variable (temperature)Controlled variables – the variables that are not changed (location, time, amount of water, number of ice cubes, type of thermometer)
8 ProcedureTo receive full credit for this section, your procedure should include evidence of your controls and where you repeated your experiment to support your results. Each step should be numbered and clear enough to be followed by another student scientist.Gather the materials and find a large workspace.Check and record the room temperature of your work area.Measure 1 cup of cold water and 3 ice cubes of the same size into each of the styrofoam, paper, glass, and plastic cups.Check the temperature of each cup of water. They should all be the same.Record the starting temperature on your record sheet.Set the timer or stopwatch for 15 minutes. Avoid handling the cups so your body temperature doesn’t effect the temperature of the water.After 15 minutes, record the water temperature again.Continue to check and record the water temperature in fifteen minute intervals until the ice has melted in each water sample.Empty then refill the cups with new cold water and ice cubes to begin the experiment again so as to confirm your results. This experiment should be completed at least three times.
9 ResultsTo receive full credit for this section, your results should be presented in three ways:well labeled, informative graphs that are easy to readtables showing the data used for the graphwritten summary explaining your results
10 ConclusionTo receive full credit for this section, your conclusion should cite the results of your experiment as well as explain any possible applications of the results.Using our example experiment comparing the effectiveness of styro- foam, plastic, glass, and paper in keeping water cold, the conclusion might look something like this:My hypothesis that the styrofoam cup would keep the water the coldest for the longest amount of time was incorrect. As you can see from my results, the water in the glass stayed above room temperature for 1.5 hours while the closest other material, the paper, was only 1.25 hours. An application for these results is that from now on I am going to drink my beverages in a glass rather than a paper, plastic, or styrofoam cup.
11 If Results Don’t Support the Hypothesis Do Not:change the hypothesisleave out experimental results that do not support your hypothesisDo:give possible reasons for the difference between your hypothesis and the experiment resultsgive ways that you can experiment further to find a solution to the problem.
