Concord Consortium
The Concord Consortium: Molecular Workbench: A Suspended Rope
Adjust the elasticity and mass of a rope suspended between two points to see how it will be affected by gravity.
Better Lesson
Better Lesson: Falling Objects
Students will determine if objects fall at the same speed by testing a variety of objects as they let them fall from above. They will learn that gravity is the force that is pulling on the object. Included in this instructional activity...
