Our lessons explore foods by connecting them to traditional concepts taught in secondary STEM education. Most lessons use a "sense-making" approach: essentially experiencing a food or recipe and then making sense of the process and product through use of observations, science concepts and building off of each other's ideas.

 

Most of our lessons include a hands-on lab or activity students can either do themselves or watch us do. To support and empower students in making connections and understanding the science concepts behind these foods, we design ready-to-go classroom slides, write anchor readings/articles, and produce videos. We also design student activities and worksheets that encourage further engagement and critical thinking.
