ScienceIn an experiment three values are close to one another but all are far from the accepted value. What does this situation indicate?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsHard ScienceA student investigates the relationship between light intensity and the rate of photosynthesis. What could be a suitable indicator of photosynthesis rate?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsHard ScienceWhich observation would be considered the most objective?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsHard ScienceIf all measurements in an experiment are consistently higher than the true value what type of error does this suggest?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsHard ScienceA plant grew by approximately two centimetres per day. What type of statement is this?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsHard ScienceWhich question requires the greatest revision to become suitable for scientific investigation?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsHard ScienceA student placed a thermometer in hot water and recorded the value immediately. What should have been done for a more reliable observation?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsHard 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 scientist recorded only the data that supported the expected idea. This is an example of which problem?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsHard ScienceWhich option includes both a qualitative and a quantitative observation?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsHard ScienceA student asks how surface area affects the rate of evaporation. Which factor is most essential to keep the same for a fair test?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsHard ScienceWhich statement gives a conclusion rather than an observation?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsHard ScienceIn an experiment plants received different amounts of fertiliser but each plant also received a different amount of water. What is the main weakness of this investigation?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsHard ScienceA student measured three times and obtained values of twelve point one centimetres twelve point two centimetres and twelve point one centimetres. What do these values mainly indicate?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsHard ScienceWhich scientific question states both the independent and dependent variables most clearly?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 ScienceA student concluded that more light increases plant growth but the dark group had a smaller initial size.
