ScienceWhich hypothesis is the most scientific and testable?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceA student concluded that more fertiliser makes all plants grow faster after testing only one plant species. What is the main flaw in the conclusion?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceA student measures plant growth only by leaf number while the hypothesis concerns total biomass. What is the main problem?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceA student claims that plants grow faster in red light than in blue light. What would be the null hypothesis?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceA student predicts that greater light exposure will increase plant growth. What is the independent variable in this test?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceA student selects only the tallest plant to report the effect of fertiliser. What problem does this illustrate?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationMediumScienceWhich statement presents a scientific conclusion with appropriate caution?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationMediumScienceIn which experiment is a control group most needed?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationMediumScienceIf two groups of plants have different soil types how will this affect an investigation of light?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationMediumScienceIn which example is the dependent variable being measured regularly?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationMediumScienceWhich plant will be the control group in an investigation of fertiliser effect?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationMediumScienceIn an experiment a student tests how light duration affects plant growth. What is the dependent variable?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationMediumScienceA student believes that a plant will grow faster when it receives more light. What is the independent variable?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationMediumScienceHow can the term plant growth in a hypothesis be changed into a clear measurement?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationMediumScienceWhich statement has the correct form of a hypothesis?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationMediumScienceWhich conclusion stays within the limits of experimental data?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationMediumScienceInitial and final plant heights were recorded in an experiment. How will growth be determined?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationMediumScienceIf the hypothesis states that plant growth will increase with more light what is the independent variable?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationMediumScienceA question asks whether giving more water makes a plant grow better. How should the word better be made scientific?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsExpertScienceA student observes that two plants kept at the same place grow differently. Which is the most scientific question to investigate the difference?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsExpert
