A good hypothesis is not simply a guess.

Explanation:

Hypotheses should be based on previous knowledge of the topic. If you're going to drop an egg off the roof of your house, you have previous knowledge that eggs are fairly fragile, so your hypothesis would probably be that the egg would break.

However, if you're hypothesising about about a topic that you don't know a lot about, or if you are making a more specific hypothesis, sometimes your hypothesis will not be supported by your experiment. For example, if you're dropping an egg onto a layer of wool, and testing different numbers of layers to see how many layers of wool you need to lay down before the egg breaks, you might guess 10 layers of wool when the answer was actually 15. This doesn't mean that your experiment is useless, just because your hypothesis was incorrect, it just means that you've learned something new, and if you repeat the experiment, you'll be able to make a more accurate hypothesis.
