change the acceleration of a falling object?
A science activity which compares the acceleration of a book and a piece of paper.

Back to Gravity
Groups of students were given an old book, a piece of white paper, and a
scissors. They skillfully cut the paper to be the same length and width of the book.
First, they dropped the paper and the book at the same time, same height, and same
direction. They recorded their observations in a data table. Each group attempted to try
numerous methods of changing the shape of the paper, so the paper will hit the floor at
the same time as the book.
We're having fun!
Even though objects free fall at the same acceleration rate, air resistance does influence the accelerations of different objects by their shape, speed, density, and size.
