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 researcher wants to test if salt concentration affects the rate of photosynthesis in algae. Write a possible hypothesis for this experiment.
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.
A researcher hypothesizes that 'increasing light intensity will increase the rate of photosynthesis up to a certain point.' Is this hypothesis testable? Yes or No.

A researcher hypothesizes that 'increasing light intensity will increase the rate of photosynthesis up to a certain point.' Is this hypothesis testable? Yes or No.
True or False: A hypothesis can be based on previous scientific studies.
True or False: A hypothesis can be changed or revised based on new evidence.
True or False: A hypothesis can be considered a theory if it is supported by a single experiment.
