Hypothesis Formulation
Biology ⇒ Scientific Inquiry and Experimental Design in Biology
Hypothesis Formulation 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 Hypothesis Formulation.
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 10

Describe how you would identify the independent and dependent variables in a hypothesis.
Describe the difference between an observation and a hypothesis.
Explain the role of prior research in hypothesis formulation.
Explain why a hypothesis should be falsifiable.
