Answer: Must be testable
Step-by-step explanation:
A hypothesis is one of the most crucial steps when conducting a science experiment. Without a hypothesis, you won't know what you expect.
The hypothesis is a guess backed by reasoning before you start an experiment. It should be testable, and relating to your experiment because if it's not related to your experiment, you won't have anything to compare the experiment to when you're reflecting on the experiment and data.
An example of a hypothesis would be if you're comparing 4 types of candle sizes and seeing which one will burn all its wax last. Your hypothesis can be I think the 3rd candle will take the longest to burn since it has the largest diameter and is the tallest.
Hope that helped a lot. Let me know any further questions.
