Sources of Error in Experiments starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Sources of Error in Experiments.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 8
A student measures the length of a leaf three times and gets slightly different results each time. What type of error is this?
A student records the wrong value in their data table. Is this a random or systematic error?
A student uses a measuring cylinder with a crack, causing some liquid to leak out. What type of error does this cause?
A student uses a ruler with faded markings, making it hard to read measurements. What type of error is most likely to occur?
A student measures the length of a leaf three times and gets slightly different results each time. What type of error is this?
A student records the temperature as 25°C instead of 35°C. What type of error is this? (1) Systematic error (2) Random error (3) No error (4) Environmental error

Which of the following best describes random error? (1) Errors that occur in a predictable way (2) Errors that happen by chance and are unpredictable (3) Errors caused by faulty equipment (4) Errors due to incorrect calculations
A student forgets to zero the balance before weighing a sample. This is an example of ______ error.
Fill in the blank: ______ error is caused by unpredictable and uncontrollable factors.
Fill in the blank: ______ error occurs when the same mistake is made every time an experiment is repeated.
Fill in the blank: ______ errors are caused by unpredictable changes in the environment, such as temperature fluctuations.
Is it possible to completely eliminate all sources of error in an experiment?
Is using dirty glassware a possible source of error in a biology experiment?
True or False: Calculation mistakes are a type of human error.
True or False: Environmental factors like humidity and temperature can be sources of error in biology experiments.
