Embodiment Construction

[0007] In order to facilitate the understanding of the specific implementation of the present invention, it is now described in conjunction with the drawings of the description: first, use solid wood or other hard materials to make a rectangular base (1-1) of suitable size, thickness, and length, and use two The hinge (1-2) is connected with the matching inclined-plane bottom plate (2-1), so that it can be opened and closed conveniently, and forms a continuously adjustable angle during the opening and closing. Paste a rectangular panel (2-2) and (2-3) with obvious smoothness on the front and back of the experimental operation surface of the inclined bottom plate (2-1), respectively, on the inclined bottom plate (2-1) close to the hinge ( One side of 1-2) is wedged with a screw rod (2-4) of suitable size and length with a nut as a slope positioning rod, on the other end of the slope base plate (2-1) away from the hinge (1-2) Install two eyelets or fixed hooks (2-5) respectively...

Abstract

The invention provides a multipurpose experimental tool for science lessons. The multipurpose experimental tool is composed of a rectangular base (1-1), a beveled bottom plate (2-1), a protractor (3-1) and other main components, wherein the beveled bottom plate (2-1) and the protractor (3-1) are matched with the rectangular base (1-1). The experimental tool integrates multiple experimental functions of the science lessons in elementary and secondary schools, such as exploration on the relations between labor-saving conditions of an oblique plane and the gradient of the oblique plane, exploration on the magnitude of friction and the smooth degree of the surface where the experimental tool makes contact with an object, and comparison of the liquid viscosity with the liquid flowing speed, teaching experimental requirements of the science lessons in the elementary and secondary schools can be effectively met, the experimental tool can be used for multiple purposes and is very high in application value.

Description

technical field [0001] The present invention is a kind of multi-purpose scientific experiment equipment. It integrates the functions of various scientific experiments such as the relationship between the labor-saving situation of the slope and the slope of the slope, the magnitude of the friction force and the smoothness of the contact surface of the object, and the comparison of the viscosity of the liquid and the speed of its flow. The teaching experiment requirements of science classes in primary and middle schools should be multi-purpose. Background technique [0002] In the teaching of science courses in primary and middle schools, it is necessary to explore the relationship between the labor-saving situation of the slope and the slope of the slope, the friction force and the smoothness of the contact surface of the object, and the comparison of the viscosity of the liquid and the speed of its flow, etc. experiment. However, traditional teaching aids are all loose com...
