North Carolina State University researchers developed a food-based learning intervention called "More PEAS Please!" for Head Start children in three North Carolina counties. The team, led by Virginia Stage, used both quantitative and qualitative methods to study the program. The study compared more than 125 students who received the intervention with almost 150 who did not.
One unit taught children about seeds: students handled different seeds, observed germination, and tested plant growth in different environments, such as with and without sun and water. They also prepared a simple seed salsa with tomatoes and corn. Teachers attended an all-day workshop early in the year and received supplemental resources; short YouTube whiteboard videos offered extra training.
Results showed positive effects: children in the food-based lessons increased their understanding of scientific concepts four times more than the comparison group, and their vocabulary grew by almost 20% compared with a 6% increase in the other group. Teachers reported improved skills in communicating science and nutrition through food activities.

Discussion questions
- Do you think hands-on food activities help children learn science? Why or why not?
- How could teachers in your area use simple seed activities in their classes? Give one example.
- Which part of the program (hands-on work, cooking, or teacher training) seems most important to you? Explain briefly.
