If we are testing how long different ball types take to roll down a ramp, what is one variable that must stay the same?
(The height of the ramp, the surface of the ramp, the way the ball is released, etc.)
True or False: A fair test must always be done inside a science lab.
(False—fair tests can be done anywhere, as long as variables are controlled.)
Why is it important to record results accurately in a fair test?
(So we can compare results and draw correct conclusions.)
What is a hypothesis in an experiment?
(A prediction or educated guess about what will happen in the test.)
True or False: In a fair test, we can change two things if we think it will make the test better.
(False—you can only change one thing at a time to keep it fair.)
If we are testing how different surfaces affect how far a toy car rolls, what is the independent variable?
(The type of surface.)
If we are testing which type of paper plane flies the farthest, name one thing that must stay the same.
(The way we throw the planes, the force used, the wind conditions, etc.)
What do scientists do with their results after a fair test?
(They analyse the data, look for patterns, and write a conclusion.)
