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 11

A scientist hypothesizes that 'increasing the amount of carbon dioxide will increase the rate of photosynthesis in plants.' What is the dependent variable?
A student hypothesizes that 'plants grow faster when given more sunlight.' Identify the independent variable in this hypothesis.
A student wants to test if the type of soil affects plant growth. Write a suitable hypothesis for this experiment.
Describe how background research can help in formulating a hypothesis.

Describe the relationship between a hypothesis and an experiment.
Explain the role of a null hypothesis in scientific experiments.
Explain why a hypothesis should avoid vague terms such as 'better' or 'worse.'
