Variables in Experiments
Biology ⇒ Scientific Inquiry and Experimental Design in Biology
Variables in Experiments starts at 6 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Variables 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
Describe what a fair test is in the context of scientific experiments.
Describe what would happen if controlled variables are not kept constant in an experiment.
Describe what would happen if more than one variable is changed in an experiment.
Explain the difference between an independent variable and a dependent variable.
Explain why it is important to control variables in an experiment.
Explain why it is important to identify variables before starting an experiment.
Explain why only one independent variable should be changed in a fair test.
In a study to see if music affects plant growth, what is the dependent variable?
In an experiment testing the effect of sunlight on plant growth, what is the independent variable?
In an experiment to test the effect of fertilizer on plant height, what is the dependent variable?
