Move it! This unit explores Newton’s Laws of Motion. Students have fun exploring the concepts of forces and changes in motion, action and reaction, angular momentum, and pendulums. A variety of hands-on investigations and related activities help learners make sense of motion.

Engineering Connection

Whether designing objects that move or stay put, understanding Newton's Laws of Motion helps engineers of all disciplines quantify the "invisible" forces acting on all objects. For example, engineers take advantage of their understanding of rotational inertia and angular momentum to maximize the thrilling spin experience on amusement park rides. Besides being used in clocks, engineers use pendulums in equipment to detect earthquakes, design buildings to resist shaking due to earthquakes, and help robots balance.

Lower Elementary Lesson
The Science of Swinging

Students learn what a pendulum is and how it works in the context of amusement park rides. While exploring the physics of pendulums, they are also introduced to Newton's first law of motion — about continuous motion and inertia.

Middle School Lesson
Ring around the Rosie

Students learn the concept of angular momentum and its correlation to mass, velocity and radius. In an associated literacy activity, students use basic methods of comparative mythology to consider why spinning and weaving are common motifs in creation myths and folktales.

High School Lesson
A Tale of Friction

High school students learn how engineers mathematically design roller coaster paths using the approach that a curved path can be approximated by a sequence of many short inclines. They apply basic calculus and the work-energy theorem for non-conservative forces to quantify the friction along a curve...

Lower Elementary Activity
Swinging with Style

Students experientially learn about the characteristics of a simple physics phenomenon — the pendulum — by riding on playground swings. They use pendulum terms and a timer to experiment with swing variables. They extend their knowledge by following the steps of the engineering design process to desi...
