This resource appears to be designed to build towards this disciplinary core idea, though the resource developer has not explicitly stated so.
Comments about Including the Disciplinary Core Idea
While this lesson is targeted for Grades 3-5, students are not expected to understand electrical charges at the atomic level. Instead, teachers should use all information presented on the movement of electrons to reinforce their own knowledge, and to understand what students will be expected to know going forward. The investigative activities in this lesson should therefore focus solely on providing students with the experiences that will develop their understanding of static electricity as a force that can attract or repel between objects at a distance. While this lesson will develop student’s understanding that the size of the force depends on the distances between objects, they will need many more experiences in order to determine how the properties of the objects affect the size of the force. In addition to the activity extensions, it is recommended that the related resource “Charge It” be implemented as it will provide students further opportunities to make sense of these phenomena: https://www.teachengineering.org/view_activity.php?url=collection/cub_/activities/cub_electricity/cub_electricity_lesson02_activity1.xml
