SCIENCE PRACTICE TEST1.Use the tables below to answer the question.Investigation 1SwingChain LengthNumber of Swingsin 60 SecondsRelease Point1250 centimeters18Full2220 centimeters20Full3190 centimeters22FullInvestigation 2SwingChain LengthNumber of Swingsin 60 SecondsRelease Point1250 centimeters18342220 centimeters20123190 centimeters2214Students perform an investigation using the swings on a playground. One of the students sits onswing 1. The swing is pulled as far as it could go and is released. The students count the numberof swings in 60 seconds. The same student sits on swings 2 and 3, and repeats the procedure.The students perform a second investigation, but this time with three different release points. Thestudents want to find out if the release point affects the number of swings in 60 seconds. Theyconclude that the release point does not affect the number of swings in 60 seconds. What is theexperimental design flaw in their second investigation?A.chain length and time are both changedB.all variables are controlled except chain lengthC.release point and chain length are both changedD.all variables are controlled except release pointSP12S08XP013635006 / I1Go on to the next page.
