Food Systems Lessons

If your class is interested in growing food at school, or exploring how to purchase local food for the school cafeteria, you should look through the lessons in this section. They will guide students through a process of examining where the food served in the school cafeteria comes from, calculating the energy use associated with transporting that food, and looking for better options. Students can explore the possibility of starting a school vegetable garden, and will go through the planning process to design and hopefully build one.

Lessons are listed in order in the menu to your right. Each lesson is available as a pdf linked on the page.

Seventh Grade Ohio Science Standards Addressed by the Lessons in this Unit

  • Explain how energy can change forms but the total amount of energy remains constant.
  • Investigate the great variety of body plans and internal structures found in multi-cellular organisms.
  • Investigate how organisms or populations may interact with one another through symbiotic relationships and how some species have become so adapted to each other that neither could survive without the other.
  • Explain how the number of organisms an ecosystem can support depends on adequate biotic (living) resources and abiotic (non-living) resources.
  • Explain that photosynthetic cells convert solar energy into chemical energy that is used to carry on life functions or is transferred to consumers and used to carry on their life functions.
  • Investigate the great diversity among organisms.
  • Analyze alternative scientific explanations and predictions and recognize that there may be more than one good way to interpret a given set of data.
  • Identify faulty reasoning and statements that go beyond the evidence or misinterpret the evidence.
  • Use graphs, tables and charts to study physical phenomena and infer mathematical relationships between variables
  • Design and build a product or create a solution to a problem given two constraints
  • Explain how needs, attitudes and values influence the direction of technological development in various cultures.
  • Describe how decisions to develop and use technologies often put environmental and economic concerns in direct competition with each other.
