    Abstract: An interactive scholastic teaching device may use first and second portions of a touchscreen for presenting problems and receiving answers to the problems from a user. The first portion of a touchscreen display is used for presenting one or more scholastic problems for a user during a problem session, and the second portion of the touchscreen display is used for recording one or more traces manually input by the user on the second portion of the touchscreen display during the problem session. A memory stores the one or more traces. The touchscreen display may also include a third portion having one or more touch buttons structured to accept input from the user during the problem session, which may also be stored in the memory, and associated with the stored traces. The traces may be stored in image form, moving image form, or in data that may be re-created to form a moving image.

  • Patent number: 7637742
    Abstract: A carbon dioxide gas buoyancy experiment device that can demonstrate how the buoyancy force acts against the force of gravity and how an object's buoyancy in a fluid can be manipulated by altering the object's density. The device demonstrates how the buoyancy force works in practice by submerging bundles of hydrophobic fingers capable of collecting gas into a gas releasing liquid such as soda. As the finger bundles collect gas bubbles released by the liquid, the volume of the submerged finger bundles increases, thereby increasing their buoyancy and causing the finger bundles to ascend and float in the liquid. The finger bundles can be pushed back down in the liquid, but will rise again due to the increased buoyancy imparted by the gas bubbles that adhere to the finger bundles.
