What is the amount of fertilizer?Class 9Exploration: Entering the World of Secondary ScienceVariables in an experimentEasy ScienceIn an experiment pot size also changes while water amount is varied. What is pot size called?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationExpert ScienceA student hypothesises that more fertiliser will increase plant growth. Which result would provide the strongest support?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationExpert ScienceWhich hypothesis defines both the independent and dependent variables most clearly in operational terms?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationExpert ScienceAn investigation finds that plants receiving more water were taller. What conclusion cannot be drawn from this relationship alone?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard ScienceA student concludes that red light increases plant growth but used only one plant. What is the most appropriate evaluation?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard ScienceA student records only final plant height but not initial height when measuring growth. What is the main problem?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard ScienceA student investigates whether fertilizer amount affects plant growth. If the pot with more fertilizer also receives more light what is the main problem?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard ScienceWhich option is the best example of an operational definition?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard ScienceA student used a different type of soil for each group in a plant growth experiment. What type of variable did soil become?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard
