Checklist
Problem definition
Is it a logical question?
Is there only 1 difference with the control group?
Hypothesis
Did you use:
If...... then.....
for example:
If
I replace water with lemon juice,
then
my seeds will germinate faster
Materials
Are all materials listed, and how much / many?
Experiment
Explain exactly what you did?
