| In the _________ phase, you will carry out the strategy you developed for testing the hypothesis.experimentA hypothesis must be:testableThere are two, two-sided dishes in the pillbug experiment. In one dish, you should have placed sand in both sides. In the other dish, you should have placed ______ in one side and ______ in the other. Sand, cornstarchMatch the action to the appropriate phase of the scientific method1. draw graphs, evaluate the hypothesis2. document results3. carry out the strategy, collect measurements4. formulate a hypothesis and create a strategy4 hypothesis3 experiment1 analysis2 reportWhen utilizing the scientific method, there are two types of variables. They are:dependent and independentBefore you begin a scientific experiment, you should:decide on a strategy------When graphing your data, it is important toPlace the dependent variable on the X-axis In the experiment phase the student carries out the strategy and collectmeasurements.In the analysis phase the student draws graphs and evaluates the results.In thereport phase the student share the results by composing a report.In part two of the lab, 20 motile pillbugs are used in the experiment.Cornstarchcontaining organic nutrients and sand cleaned of contaminates are used on each side of a twochoice chamber.The hypothesis formulates a tentative explanation to a posed question orobservation.In the lab, the hypothesis is that the pillbugs will move more towards the cornstarch than the sand, displaying a greater preference for the corn starch.A choice chamber isused to test preference.Various substances will be placed in the presence of pillbugs in acontrolled environment.The strategy is to place 10 pillbugs in a separate chamber with cornstarch on one side andsand on the other.Then, 10 other pillbugs are placed in a chamber with cornstarch on one sideand nothing on the other.The chamber with the greater number of pillbugs on the side with thematerial identifies the preference for pillbugs.The pillbug movement will be measured at 1-minute intervals and one final 10-minute interval.There will be a control chamber consisting of10 pillbugs placed in an area with no material on one side and sand on the other.A positive |
