I found an Aims curriculum book titled, Cycles of Growing and Knowing. Within this book there are many lessons that encompass the ideas of plant cycles and also human cycles of growth. All of the lessons not only integrate math and science but rely on math to accomplish the collection of data or data analysis. Similar to the jet toy lesson the pumpkin lesson also involved the processes of observing, collecting and recording data, and comparing and contrasting. But since the science of this lesson was life science and the jet toy challenge was about physics, the two are very different challenges. Both of the lessons relied on observation, predictions and class discussion as components of their success.
