I have a hypothesis question...?

Question

A section of land is devoid of plants. A student stated the following hypothesis: Plants do not grow here because of lack of sunlight. Is this a valid hypothesis? Explain

Best answer gets 10 points!

Answer 1

A valid hypothesis is one which is capable of being tested. If this hypothesis is capable of being experimentally tested then the hypothesis is valid. I will leave it up to you to decide if this hypothesis is testable by experiment.

Answer 2

One shouldn't state a hypothesis negatively.  The way you test a hypothesis is to make an attempt to prove it wrong. But you can't disprove a negative!  Oh, and you can't provide more sunlight.  How about "Plants can be made to grow here by providing more light."

Answer 3

Yes. Because plants need sunlight to photosynthesise to then produce glucose which they then use for respiration and growth. Without sunlight > no photosynthesis > no growth
