Caroline's+Experiment

To show how plants need light, I will challenge a plant to grow around obstacles to reach its energy source.

My experiment for this PBL project will involve phototropism, a growth response between a plant and an external stimulus, light. Plants generally grow towards a source of light, so my experiment will be inside a shoebox maze, where the plant must grow towards the light around some obstacles. I will tape pieces of cardboard inside a box 1/3 of the way on each side, and cut a hole at the top. The plant will be thoroughly watered and placed at the bottom of the box, with the hole at the top. After a week I will open the box and see how the plant grew sideways to reach the light.
