Mastering Hypotheses Flashcards
(16 cards)
What is a hypothesis?
A hypothesis is a clear, testable statement that predicts what will happen in an experiment and tells you what you’re measuring.
Why is a hypothesis more than a guess?
Because it is based on observations and predicts a measurable outcome.
What does a hypothesis connect?
It connects the independent variable (what you change) and the dependent variable (what you measure).
What format helps in writing a hypothesis?
The ‘If…then…because…’ format.
What is the independent variable?
The factor that you change in an experiment.
What is the dependent variable?
The factor that you measure in response to changes.
Give an example of a hypothesis using oil and butter in cookies.
If I use oil instead of butter in my cookies, then the cookies will spread more during baking because oil is liquid at room temperature and doesn’t hold shape like butter.
Why is writing a good hypothesis important?
It helps you stay focused, collect the right data, explain results clearly, and communicate like a scientist.
Why avoid vague hypotheses?
Because they do not clearly define what is being changed or measured.
Why avoid non-testable hypotheses?
Because they don’t provide measurable outcomes.
Why is it important to include variables in your hypothesis?
To make it clear what is being changed and what is being observed.
What is a good activity to practice writing hypotheses?
Think of a kitchen experiment, identify variables, and write a hypothesis using the ‘If…then…because…’ format.
How can you tell if a hypothesis is testable?
It should predict a measurable change that can be observed.
What should every hypothesis include?
What you’re changing, what you expect to happen, and why.
What role does reasoning play in a hypothesis?
It explains the scientific reason behind the expected outcome.
What’s the benefit of using a structured hypothesis format?
It clarifies your experiment’s focus and improves communication.
