Kye, Hannah – Science and Children, 2019
In this article, second graders learn the basics of engineering through an exploration of magnetic levitation (maglev) technology. The author designed and taught the lessons to a class of 26 students enrolled in a month-long summer science program. The maglev lessons took place over three mornings (15 minutes for the first lesson and 40 minutes…

Bakke, Leanne; Kieke, Michele C.; Krueger, Robert – American Biology Teacher, 2013
In daily life, students are allowed to use words such as "more," "some," or "increase-decrease" to describe the relationship between two events. In science, concise description is necessary, which requires the contribution of math. In the summer component of the Science Research Institute program, students integrated…
