How Does Light Help Me See Things And Communicate With Others?
In this first grade unit, students start by exploring how many shapes can be seen in various locations around a darkened classroom on different pieces of paper. They can not see all the shapes in these conditions. This leads students to start noticing and wondering about other phenomena related to seeing in the dark, which in turn leads to new questions about how they can make their room completely dark.

Why Is Our Corn Changing?
In this second grade unit, students investigate the mystery of harvest corn, something they saw as decoration, beginning to sprout what look like leaves and roots. Disagreements about how the corn is growing spark investigations that lead students to uncovering the functions of different parts of the plant as well providing evidence for what plants need in order to grow.
