ScienceIn an experiment seed germination was measured at different temperatures but each group contained a different number of seeds. What problem will this cause?Class 9Exploration: Entering the World of Secondary ScienceVariables in an experimentHard ScienceWhich hypothesis is most scientific for investigating the effect of temperature on seed germination?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationExpert ScienceIn the same investigation what type of variable is the number of germinated seeds?Class 9Exploration: Entering the World of Secondary ScienceVariables in an experimentEasy ScienceWhat is the independent variable while testing the effect of water amount on seed germination?Class 9Exploration: Entering the World of Secondary ScienceVariables in an experimentEasy ScienceIn which experiment is a large sample size most necessary to handle natural variation?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationExpert ScienceA student tests seed germination at three temperatures but uses a different seed type at each temperature. Why will interpretation be difficult?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard ScienceSeed germination was tested in two groups. One group had twenty seeds and the other had only two. What is the main weakness of the conclusion?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard ScienceA student tested seed germination at different temperatures but gave different amounts of water to each group. Why will interpretation be difficult?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard ScienceIn an experiment the amount of water was changed and seed germination was observed. Which graph would be most useful?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationMedium ScienceSeed germination was tested at different temperatures. What could be an appropriate control group?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationMedium ScienceWhich factor should be kept the same when comparing germination of large and small seeds?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationMedium ScienceIn which experiment is a control group most necessary?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationMedium ScienceA student hypothesises that seeds will germinate faster with more water. What will be the dependent variable in this investigation?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationEasy ScienceWhat can be measured to test the effect of water on seed germination?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationEasy ScienceWhich statement is a suitable hypothesis for an experiment?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationEasy ScienceIn a seed germination investigation a student records only germinated seeds and ignores those that did not germinate. What problem does this illustrate?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsExpert ScienceThree groups of seeds were kept at different temperatures but each group contained only one seed. What is the best way to increase the reliability of the conclusion?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsHard ScienceA student investigates whether soil acidity affects seed germination. Which is the most appropriate dependent variable?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsHard ScienceWhich conclusion is reasonably supported by the available observation?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsHard ScienceA student wrote that not all seeds germinated because the seeds were defective. What type of statement is this?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsHard
