Step 3 - Asking a question
|Making a prediction/hypothesis|
When we increase/decrease
... we think that the
number of seeds germinating
will increase / decrease / stay the same
At this stage, pupils are being asked to select the variable they want to investigate. They choose one of the things that they have said they could change and one of the things that they said they could measure.
The question posed is: If I change this (the chosen variable or independent variable), what will happen to that will increase / decrease / stay the same (the chosen measurement or dependent variable)?
