Students would observe three bio-bottles with the same types and amount of plants, but each one of them under a different light intensity. All of the bio-bottles would have the same conditions of watering.
After visually observing and recording the growth, students would then burn and dry the plants, weighting the dried remains to compare resulting mass.
