$100 Question - QuestioningA student asks the question, “What is a plant?”Why is this NOT a testable question?
$100 Answer - QuestioningBecause it cannot be answered through aninvestigation.
$200 Question - QuestioningGive an example of a question that is NOTtestable.
$200 Answer - QuestioningStudent answers will vary. The question shouldbe one that could NOT be answered throughconducting an investigation using the steps ofthe Scientific Method.
$300 Question - QuestioningGive an example of a question that IS atestable question.
$300 Answer - QuestioningStudent answers will vary. The questionshould be one that could be answered throughconducting an investigation using the steps ofthe Scientific Method.
$400 Question - QuestioningRead the following question: “Do plantsneed sunlight to live?” Is this a testablequestion? If not, tell why. If yes, explain howthe investigation would be conducted.
$400 Answer - QuestioningYes, it is a testable question. Two similar plantswould be used. One would be placed in sunlightand the other would be kept completely out ofsunlight. Both plants would be in the same sizedpot, with the same amount and type of soil, andgiven the same amount of water each day.
$500 Question - QuestioningRead the following question: “What is thefavorite t.v. show of Old Pointe 5th Gradestudents?” Is this a testable question? If not, tellwhy. If yes, explain how the investigation wouldbe conducted.
$500 Answer - QuestioningNo, it is not a testable question. It would onlyrequire that the students be asked theirfavorite t.v. shows. The results would then becounted. This is only making observations, notconducting an investigation.
$100 Question - HypothesizingAt what point in the Scientific Method does theStep of hypothesis occur?
$100 Answer - HypothesizingAfter formulating a question, beforeinvestigating/experimenting.
$200 Question - HypothesizingIn order for a hypothesis to be stated correctly,it must be stated like it is a _______________.
$200 Answer - HypothesizingFact.Hypotheses are not supposed to sound likeguesses. They should sound like true, factualstatements. Then, the point of the experiment/investigation phase is to prove the hypothesisstatement to be either correct or incorrect.
$300 Question - HypothesizingA student stated the following hypothesis:“An object that is pushed with equal force willtravel less distance on a rough surface andgreater distance on a smooth surface.”Is the hypothesis stated correctly? Why or whynot?
$300 Answer - HypothesizingYes, it is stated as a fact. Next, the student willconduct an experiment to prove their hypothesisto be accurate or inaccurate.
$400 Question - HypothesizingA student stated the following hypothesis:“An object that is pushed with less force willprobably travel less distance than the sameobject when it is pushed with a greater forceif the objects are on the same surface.”Is the hypothesis stated correctly? Why or whynot?
$400 Answer - HypothesizingNo, it is not stated correctly. The wordprobably makes it so that it is not stated as a fact.
$500 Question - HypothesizingA class was given the task of answering thefollowing question by using the Scientificmethod: “Which type of fertilizer will make atomato plant grow the most: compost, cowmanure, or a store bought brand?”Give an example of a hypothesis that could bestated for this investigation.
$500 Answer - HypothesizingStudent answers will vary.Ex: “Tomato plants grow the most whenfertilized with compost.”
$100 Question - VariablesName the three types of variables that need tobe considered in an experiment.
$100 Answer - VariablesIndependent, dependent, and controlled variables.
$200 Question - VariablesExplain what controlled variables are in anexperiment.
$200 Answer - VariablesControlled variables are the aspects that are keptthe same for all trials. For example, if anexperiment is designed to test how the amount ofwater affects a plant’s growth, then the type ofplant, type and amount of soil, size of pot, andamount of sunlight must be kept the same. Theseare controlled variables.
$300 Question - VariablesWhat is an independent variable in anexperiment?
$300 Answer - VariablesAn independent variable is the aspect of theexperiment that is being tested. For example, ifan experiment is designed to test how the amountof water affects the growth of a plant, then thedifferent amounts of water given to the plants isindependent variable. It is the thing that is beingtested to see what its affects are.
$400 Question - VariablesWhat is a dependent variable in an experiment?
$400 Answer - VariablesA dependent variable is the aspect of anexperiment that changes due to the differencesin the independent variable. For example, ifan experiment is designed to test how the amountof water affects the growth of a plant, then thedifferences in how much the plants grow is thedependent variable because the growth willdepend on the amount of water given.
$500 Question - VariablesA student wants to find out whether a foam cupor a metal mug keeps water warmer. He fills thetwo kinds of cups with the same amount of hotwater, making sure that the water in each cupbegins at the same temperature. He waits 15minutes, then measures the temperature of thewater in each cup.Name the independent, dependent, and controlledvariables in the experiment.
$500 Answer - VariablesIndependent Variable: The type of cupDependent Variable: The temperature of thewater after 15 minutesControlled Variables: Same amount of water ineach cup, same beginning temperature of water,temperature taken again at exactly 15 minutes inboth cups, same thermometer used.
$200 Answer - ExperimentingC – This table gives the most accurate dataabout when the plants were measured. Theinformation in the other tables is not asspecific, thus it is difficult to draw conclusionsfrom them.
$300 Answer - ExperimentingB – 80 km. After traveling 80 km, the objectstopped for an hour, between hours 2 and 3.
$400 Question - Experimenting What should Hannah do next to have useful information for her mother? B. Record when the seeds sprout and begin to grow. C. Make sure the seeds have enough sunlight. D. Predict which seeds will sprout.
$400 Answer - ExperimentingA – Record when the seeds sprout and begin togrow.
$500 Answer - ExperimentingC – During the fourth minute. The fourth minuteoccurred between minute 3 and 4. During thisminute, the airplane traveled the greatestdistance, thus it flew the fastest during this time.
$100 Answer – Wild CardH – Make graphs and diagrams.
$200 Question – Wild CardWhich is a quantitative observation?A. The car took 6 seconds to roll across the desk.B. The car is red.C. The birds made their nests in apple trees.D. The colder the air, the slower mold will grow on fruit.
$200 Answer – Wild cardA – The car took 6 seconds to roll across thedesk.This is a quantitative observation because itrelates to an amount, or quantity, ofsomething.
$300 Question – Wild cardWhich question could be answered withqualitative observations?A. How tall is the plant?B. How do the plant’s flowers smell?C. How many leaves are on the plant?D. How deep are the plant’s roots?
$300 Answer – Wild CardB – How do the plant’s flowers smell?This is a quality about the plant. All of the otherchoices related to some quantity (number)characteristic of the plant.
$400 Question – Wild CardStudy the table: Growth of Corn and Bean Plants Plant Starting Height Ending Height How Much it (After 2 Weeks) Grew Corn A 10 cm 16 cm 6 cm Corn B 14 cm 19 cm 5 cm Bean A 11 cm 21 cm 10 cm Bean B 13 cm 22 cm 9 cm Which is a valid conclusion based on the data? B. Corn takes longer to get ripe than beans do. C. Bean plants need more sunlight to grow than corn plants do. D. Bean plants grow faster than corn plants. D. Corn plants grow faster than bean plants.
$400 Answer – Wild CardC – Bean plants grow faster than corn plants.The bean plants combined for 19 cm of growth,while the corn plants combined for 11 cm ofgrowth.
Final JeopardyThink of a question that could tested. Designthe investigation. Make sure to include apossible hypothesis, and to list the independent,dependent, and controlled variables. You do notneed to analyze, draw conclusions, orcommunicate results since these would requireperforming the investigation.
Final Jeopardy AnswerAnswers will vary. Students should displaythe ability to identify a testable question, aswell as explain how the investigation wouldbe set up and conducted. Independent,dependent, and controlled variables shouldbe accurately identified.
