A. It takes energy to change the motion of objects.
B. Energy change is understood in terms of forces--pushes or pulls.
C. Some forces act through physical contact, while others act at a distance.
Clarification for grades K-5: The target understanding for students in the elementary grades should focus on Big Ideas A, B, and C.
Clarification for grades 6-8: The target understanding for students in grades 6-8 should begin to transition the focus to a more specific definition of forces and changes in motion. Net forces create a change in motion. A change in momentum occurs when a net force is applied to an object over a time interval.
Grades 9-12, Standard 12: Motion - A. Motion can be measured and described qualitatively and quantitatively. Net forces create a change in motion. B. Momentum is conserved under well-defined conditions. A change in momentum occurs when a net force is applied to an object over a time interval.
In this lesson the students will create a dance composition inspired by water and ice. Students will explore textures of water and ice via prompts and cuing given to students in order to elicit spontaneous movement responses.
In this lesson, students identify ways to make objects move while recording their techniques. Students then engineer a track that will place an object as close to an exact location as possible. Students will test and revise their tracks.
In this lesson, students learn about forces on objects such as a push or a pull. Students interact with items in their classroom testing pushes and pulls. Students explore the strength of pushes through a toy race investigation.
This Engineering Design Challenge is intended to help first grade students apply the concepts of the various ways objects can move, and that the way to change the motion of an object is to apply a push or a pull. It is not intended as an initial introduction to this benchmark.
