Objective: Are any parts that make up food molecules coming into the plant from above the surface?

We conduct an investigation and produce data showing carbon dioxide decreasing and water increasing in the air surrounding plant leaves exposed to light. We analyze and interpret secondhand data, confirm carbon dioxide and water patterns, and discover that oxygen levels are increasing around the plant. This sparks questions about how these gases are getting into and out of the leaves. 

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.

What students will figure out

• Carbon dioxide enters plants through the leaves.

• Since carbon dioxide is the only input containing carbon, it is the source of carbon in food molecules.

• Plants also release water and oxygen from their leaves.

Next Lesson We will observe the surface of leaves and see small openings that could be how gases get into and out of leaves. We will also look inside of leaves and see green chloroplasts inside plant cells and discover that they move in response to light.
