Objective: Do plants get their food molecules by taking them in?
We use a hydroponic plant system and indicators of food molecules to investigate whether soil, plant food, water, or air could be potential sources of food molecules in plants. We develop a list of candidates coming into contact with the hydroponic plants both below and above the surface that light is shining on.

Check for Understanding:
What students will figure out
Plants can grow without soil.
Water and hydroponic plant food do not have food molecules inside them according to food labels and food indicator experimental results.
Parts of food molecules might be found in water and hydroponic plant food.
Next Lesson We will revisit the composition of air and light to look for possible sources of food molecules. We will then look at air and light (in addition to water and hydroponic plant food) and we will figure out none of our initial candidates contain food molecules. We will realize that we might have to adjust our question and look to find whether plants could be putting together parts of food molecules, instead of directly taking in whole food molecules.
