Balls and Ramps
Grade Level: Second

Overview:

The ball is a universal toy that delights children of all ages. Children come to school having played with balls of many different kinds and in many different ways. They bring a great deal of familiarity with balls and intuitive knowledge of how balls roll and bounce; how easy they are to throw and to catch; which are better for certain games and which are worse. This module builds on those experiences by asking children to extend their explorations of balls, how they roll and bounce, and what they do on ramps.

The two major themes running throughout the unit include the properties and characteristics of balls and the different things that affect they way balls behave. They observe, use, and compare different balls noting the difference in materials, size, and weight. They then explore how balls are affected by gravity, inertia, momentum, and friction.

Goals:

-Explore, observe, discover, and describe the   characteristics and properties of balls and their motion
-Identify relationships between physical properties of   balls and their motion
-Introduce the concepts of gravity and mechanical energy,   velocity and acceleration, inertia, momentum, and   friction
-Communicating observations through drawing and   writing
