Objective: Where does this stuff come from?

We brainstorm foods we ate that we think come from plants, animals, or other sources. We taste maple syrup and maple sap, foods that we are surprised come from plants and watch a video of sap being extracted from a tree. This motivates us to review nutrition labels for the plant foods we ate. All the plants have some food molecules like carbohydrates, proteins, or fats. We know we get our food from eating, but how do plants get their food? Where is the food in plants coming from? We develop a model to try to explain this and come up with questions to form a Driving Question Board (DQB). We brainstorm investigations to figure out the answers to our questions. 

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.

Norm Focused Reflection 

What students will figure out

• All plant foods we looked up nutrition information for have food molecules in them. Not all of the plants have the same food molecules (carbohydrates, fats, proteins), but all of them have some sugar.

• Plants might get their food molecules from different sources (i.e., water, sunlight, soil).

• We have lots of questions about where the food in plants comes from.

• We have ideas for future investigations to pursue that could help figure out these questions

NEXT LESSON We will investigate possible sources of food molecules such as carbohydrates, proteins, and fats inside plants using a hydroponic plant system and a list of potential candidates. We will do a lab with food indicators to confirm or eliminate each candidate.
