Answer:
A hypothesis is your best edjucated guess on what the outcome of the science fair project is going to be. So you would first need to come up with the science experiment that you want to do before you can come up with your hypothesis. Example: if your science project was mixing baking soda and viniger together to see what type of reaction you will get, your hypothesis is your guess on what is going to happen when you mix the baking soda and vinegar toghter. So my hypothesis for that experiment of mixing baking soda and vinegar together is that it will foam up and over flow from the container that I mixed them in. If that happens them my hypothesis was correct. So you need to have an experiment in mind before you can make your hypothesis for the experiment.
