Prediction
Captions available
The idea
A prediction states what should happen if a hypothesis is true, often in the form "if … then." It turns an explanation into a result to look for.
In practice
If heat causes the wilting, then seedlings shaded from heat but given full light should not wilt.
Where people slip
A hypothesis explains; a prediction forecasts a measurable result of it.
