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?
Describe one way to reduce random errors in an experiment.
Describe the difference between systematic and random errors.
Describe what is meant by 'parallax error' in measurement.
Explain how calibration of equipment can reduce systematic errors.
Explain the impact of not controlling variables in an experiment.
Explain why it is important to identify sources of error in an experiment.
Explain why it is important to report sources of error in a scientific report.
Explain why repeating an experiment can help identify random errors.
If a student reads the meniscus at the top instead of the bottom when measuring liquid, what type of error is this?
What is a source of error in a scientific experiment?
