Students should grow, harvest and cook their own food. While doing so, every subject should be involved.

Chemistry and Biology are the more obvious ones for sake of soil testing, plant biology, cross pollination, and composting. Chemistry also should be involved in cooking.

Math and science classes for sake of grids, spacing, growth charting, control groups, etc as well as conservation.

Economics for understanding all of the costs involved from planting, to harvesting, to buying equipment and hiring labor, shipping to grocery stores, disposal of food that isn't purchased. Additionally, budgeting for ingredients to prepare meals.

History can bring a lot of this to life by studying agricultural history and the accompanying economics, including the world events surrounding them. I'm sure there's plenty of literature go to along with it as well.

And you can even get into computer science, engineering and robotics by setting up FarmBot's in schools, which are open source. Students can learn to use them as designed as well as program new functionality.

Help students learn by making it both beneficial, relatable and connected.
