Final answer:
A hypothesis is a possible explanation for an observed phenomenon, based on scientific knowledge and logical reasoning. It must be testable and falsifiable. Formulating a hypothesis involves asking a question, conducting research, and proposing a potential explanation.
Step-by-step explanation:
A hypothesis is a possible explanation for an observed phenomenon, and it is formulated based on scientific knowledge and logical reasoning. It must also be testable and falsifiable. For example, if you observe that plants grow taller when given more sunlight, your hypothesis could be that 'increased sunlight exposure leads to increased plant growth.'
To form a hypothesis, you need to ask a question, conduct research, and then propose a potential explanation that aligns with what is already known about the topic. Testing the hypothesis through experimentation and analyzing the results will help you either accept or modify the hypothesis.
