Description
The utility model relates to teaching aid, the recoilo experiment learning aid that especially a kind of suitable pupil uses.
Teaching aid can make the student deeply understand the content of courses taken, cultivates students'ability for practice and problem-solving ability.But because existing teaching aid more complicated, cost of manufacture is than higher, can only be for the teacher as teaching aid to student's demonstration, the student can not start, and is unfavorable for that the student deeply understands and consolidates content, and students'ability for practice and problem-solving ability are cultivated in inconvenience.Especially lack the schooling apparatus that uses for the pupil at present.
The purpose of this utility model is this problem of schooling apparatus of taking action on one's own to use for students in middle and primary schools at lacking at present, the recoilo experiment learning aid that provide a kind of simple structure, be convenient to mounting or dismounting, cost is low, makes things convenient for students in middle and primary schools, especially pupil to use.
Recoilo experiment learning aid described in the utility model comprises base plate, balloon, balloon support, gas, mouth, wheel and wheel shaft.Have tongue-and-groove and axis hole on the base plate.Balloon support one end has plug tenon, and the other end has slot.Be shaped on spout and slot on the valve.Balloon support one end is connected with slot on the base plate by plug tenon, and the other end is by the mutual cross connection of the slot on slot and the valve.Wheel shaft inserts in the axis hole of base plate versatilely.Wheel gently is pressed on the wheel shaft.Balloon is fixed on the valve.
When the student does experiment, at first balloon support, wheel and wheel shaft are contained on the base plate, valve is contained on the balloon support, balloon is enclosed within on the valve.Then, in balloon, blow up gas, whole device is placed on the desktop, just can hear the injection sound of air-flow and see that the base plate that wheel is housed moves round about this moment.What can understand thus is back attack phenomenon.
The utility model simple structure, easy to operate, cost is low, is comparatively ideal pupil's schooling apparatus.
