2 Write down a conclusion that you can make from your results.

Do they support your hypothesis?

chlorophyll is found.
I can explain why plants need magnesium and nitrate.

I can suggest a hypothesis, and plan an experiment to test it.
I can make a risk assessment of my experiment, and carry out practical work
safely.
