Abstract: A gas fixture safety cover comprising: a plurality of walls, and a plurality of nozzle slots located in the walls, and plurality of handle slots located in the walls, the walls and slots configured to allow the gas fixture safety cover to slide over a gas fixture and abut a countertop if all of the gas valve handles are in an off position, and further configured to prevent the gas fixture safety cover from sliding over a gas fixture and abutting a counter top if any of the gas valve handles are in a turned on position.

Abstract: A gas fixture safety cover comprising: a first wall; a second wall attached to the first wall, the second wall is generally perpendicular to the first wall; a third wall attached to the second wall and generally perpendicular to the second wall; a fourth wall attached to the third wall and first wall, the fourth wall generally perpendicular to the third wall and first wall; a first nozzle vertical slot in the first wall and extending to the bottom of the first wall; a second nozzle vertical slot in the second wall and extending to the bottom of the second wall and where the height of the first handle vertical slot is higher than the height of the first nozzle vertical slot; where when the gas fixture safety cover can only slide down over a two nozzle and two handle gas fixture when the two handles are both turned off; where when the gas fixture safety cover has slid onto a gas fixture when the gas valve handle is turned off, the gas fixture safety cover abuts a counter top, and where when the gas fixture safe

Abstract: A gas fixture safety cover comprising: at least one wall; at least one handle vertical slot located in the at least one wall, and the at least one handle vertical slot extends to the bottom of the at least one wall; at least one nozzle vertical slot located in the at least one wall, and the at least one nozzle vertical slot is generally perpendicular to the at least one handle vertical slot, and the at least one nozzle vertical slot extending to the bottom of the at least one wall; where the bottom of the gas fixture safety cover is opened. A gas fixture safety cover comprising: a first wall; a second wall attached to the first wall, the second wall is at least partially and generally perpendicular to the first wall; a first handle vertical slot located in the first wall and extending to the bottom of the first wall; a first nozzle vertical slot located in the second wall and extending to the bottom of the second wall; and where the bottom of the gas fixture safety cover is opened.

Abstract: A tactile biological cell model comprising: a plurality of organelle models configured to be manipulated by hand and arranged on a generally flat surface; where the plurality of organelle models are further configured to be arranged with respect to each other so as to represent the arrangement of a plurality of organelles of an actual biological cell. A tactile biological cell model kit comprising: a cell membrane model; a cell wall model; a central vacuole membrane model; a nucleus model; a plurality of chloroplast models; a plurality of amyloplast models; a plurality of chromoplast models; a plurality of coccus bacteria models; a plurality of bacillus bacteria models; and where each of the models are configured to be manipulated by hand and arranged on a generally flat surface with respect to each other so as to represent the arrangement of a plurality of organelles of an actual biological cell.

Abstract: A biological molecule puzzle comprising: at least one oxygen puzzle piece; at least two hydrogen puzzle pieces that are both simultaneously removeably attachable to the at least one oxygen puzzle piece; a first base puzzle piece removeably attachable to at least one puzzle selected from the group consisting of an oxygen puzzle piece, and a hydrogen puzzle piece; and wherein the at least one oxygen puzzle piece can be removeably attached to two hydrogen puzzle pieces to form a water molecule puzzle.
