Objective: What other inputs could be sources of food molecules for the plant?

We revisit the composition of air and light to look for possible sources of food molecules. After looking at air and light (in addition to water and hydroponic plant food) we figure out none of our initial candidates contain whole food molecules. We 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. 

Standards:

• MS-PS1-3: Gather and make sense of information to describe that synthetic materials come from natural resources and impact society. 

• MS-LS1-2: Develop and use a model to describe the function of a cell as a whole and ways parts of cells contribute to the function. 

• MS-LS1-6: Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms. 

• MS-LS2-3: Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.

We will see whether candidates from above the surface that contain parts of food molecules go into plants. We will use data we produce and secondhand data to figure out that plants are taking in carbon dioxide and releasing water and oxygen.

What students will figure out

• Air and light do not contain whole food molecules that can be taken in by plants.

• Air, hydroponic plant food, and water contain the same atoms that food molecules contain. These are parts of food molecules that could be taken in by plants.
