| titleOfInvention | A kind of chemical dissolution degree demonstration teaching aid |
| abstract | The utility model is related to a kind of chemical dissolution degree demonstration teaching aids, housing forward end is provided with cationic slot, anion slot and key-press module, cylinder is made in each cationic block and each anion block rear end, electronic tag is embedded in each cylinder, each electronic tag is encoded with unique identification.When the utility model is used, cationic block is inserted into cationic slot, anion block is inserted into anion slot, then it is dissolving combination, slightly soluble combination or precipitate combination to select combination by key-press module, it is whether correct by central control module judging result after selection, it then shows on a display screen to wrong and specific explanation, during so that content of courses involvement is started, and learnt in the form of game, effectively raise teaching efficiency. |
