Abstract: The present application is directed to methods and apparatus for playing a throwing game, employing a ball in which the surface of the ball is divided into zones, with indicia contained in each zone. In preferred examples, the ball is shaped like a football, and the indicia indicate number of points to be awarded, if any. Preferably a player catching the ball will receive the number of points indicated by the indicia within a zone on which the catching player's thumb lands. Reach player's points are added in a running tally. The invention also concerning a ball to be used in such a game.

Abstract: A vehicle for performing an experiment demonstrating a Newtonian law of motion, including capturing data representing vehicle velocity over time during execution of an experiment, the vehicle comprises an interval timer for generating a time interval output representing equal intervals of time; a velocity indicating mechanism for generating a velocity output representing a velocity of the vehicle when traveling along a path during performance of the experiment; and a memory mechanism for recording the time interval output and the velocity output during performance of the experiment, the recorded time interval output and velocity output being recorded for use in at least one calculation demonstrating the Newtonian law of motion.

Abstract: A vehicle for use as an educational toy to demonstrate elastic interaction and magnetic attraction and repulsion includes a vehicle body and wheels for movably supporting the body. A magnet is supported on the body at one end thereof and an elastic member is supported on the body at the opposite end thereof.
