Where does this matter?
Testable predictions help teams plan investigations before they spend time collecting data.
What should you keep in mind?
A hypothesis is not a guarantee. Unexpected results are useful when methods are fair and clearly recorded.

YOUR TASK
Which prediction connects a change to a measurable result?
READ THE BENCH CARD
Build a focused if–then–because prediction
Complete the three linked parts of a prediction. Use a measurable outcome and a reason that can be checked against evidence. A hypothesis is not a guarantee. Unexpected results are useful when methods are fair and clearly recorded.

BEAN SEED INVESTIGATIONCan a reader tell what changes and what is measured?
Build one prediction with a cause, a measurable result, and a reason.
