How to Write a Hypothesis Flashcards
(20 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.
What happens if you increase yeast in bread dough?
If I increase the amount of yeast in the dough, then the bread will rise higher, because yeast produces gas that makes the dough expand.
What effect does chilling cookie dough have?
If I chill the cookie dough before baking, then the cookies will be chewier, because chilling slows fat spread and lets flavors develop.
What happens if you use honey instead of sugar in muffins?
If I use honey instead of sugar in a muffin recipe, then the muffins will be more moist, because honey holds more water and reacts differently during baking.
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.
How does writing hypotheses help students?
It teaches them to think and act like scientists.
