Science Experiments

Question: How to do the results for this science experiment?

I have to write up an experiment for the effects of phototropism on plants and I was wondering what I should put in the results section other than my observations? My teacher said to include tables and graphs but I’m not sure what to put in a table or a graph that would relate to phototropism. For my experiment I used 4 cress plants and they successfully grew towards the light.

Answer: Here are a couple of ideas:
1. Angle of the leaves vs. time.
2. Angle of the stem vs time.
3. Distance from vertical to the top vs. time.

Make sure that you put the light on the opposite side and see what happens.
