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 8
A student hypothesizes that increasing the amount of sunlight will increase the rate of photosynthesis in plants. What is the independent variable in this hypothesis?
A student observes that some plants in the shade are shorter than those in the sun. What is a possible hypothesis the student could test?
A student wants to know if the type of soil affects plant growth. Write a possible hypothesis for this investigation.
