Sliding common objects, such as blocks, boxes, balls, empty containers, and even play foods down a ramp is a fun way for kids to start exploring some physical science concepts related to the position, force and motion of objects and to develop their abilities of technological design. Included in this article is a corresponding activity.
Ideas For Use
Let groups of students test a variety of small objects to see how they move. Which objects can you blow across the table? How do they move--rolling or sliding? What shape moves (rolls) the easiest? Where do you see this shape in the world? Students will discover that the small force of breath of air will move only the lightest objects or those with a round cross-section.
