How Fast Do Objects Accelerate To Earth?

WHY?

Acceleration is determined by the amount of gravity that exerts pressure on the object that is dropped. When dropping objects from a window two to three stories high, students can really see visually how objects fall down to the earth at the same rate because of the force of gravity. Determining the rate of acceleration adds to the experiment in showing how acceleration is similar whenever something drops.

ASSESSMENT: Can the student communicate what they observed?

four Student is able to communicate how the rate of acceleration is similar for two objects that weigh different amounts because of the force of gravity pulling on the objects. Student can calculate the rate of acceleration using the formula that was provided during the experiment.

three Student is able to communicate most of the information of how the rate of acceleration is similar for two objects that weigh different amounts because of the force of gravity pulling on the objects. Student can calculate the rate of acceleration using the formula that was provided during the experiment.

two Student is able to communicate some of the information of how the rate of acceleration is similar for two objects that weigh different amounts because of the force of gravity pulling on the objects. Student can calculate a portion of the rate of acceleration using the formula that was provided during the experiment.

one Student is able to communicate something about how the rate of acceleration is similar for two objects that weigh different amounts because of the force of gravity pulling on the objects.
