The HYPOTHESIS is another name for a PREDICTION. When you are writing the hypothesis you are trying to predict the answer to your question. You should always give a reason for your prediction. It can be based on prior knowledge, observations, or research and is proven true or untrue by investigation.
For example: Question:Does soaking bean seeds before planting affect how fast they
will grow?
Possible Predictions:
I think that bean plants that have their seeds soaked before planting will grow faster because it will make the hard seed covering soft.
I do not think that soaking the beans will make the bean plant grow faster because soaking the seed will just make the seed mushy.
