Abstract

The invention relates to a buoyancy experimental device and method for physics teaching. Experimental equipment for studying the magnitude of buoyancy in middle school physics is quite simple, operating is quite troublesome, visuality is bad, no experimental method is given clearly, a demonstrative experiment and a grouping experiment cannot be well completed, and the teaching effect is poor. The bottom ends of supporting rods are connected with an adjustable base, and the top ends of the supporting rods are connected with an adjusting device. The adjusting device is connected with weights, water tanks are placed under the weights, and the water tanks are filled with water or solutions. An overflowing opening is formed in the upper edge of each water tank, and a square cup is placed under each overflowing opening. The buoyancy experimental device and method are used for buoyancy experiments in physics teaching.

Description

technical field [0001] The invention relates to a buoyancy experimental device and an experimental method for physics teaching. Background technique [0002] The experimental equipment for studying buoyancy in junior high school physics is relatively simple, the operation is cumbersome, the visibility is not good, the experimental method is not clearly given, the demonstration experiment and group experiment are not easy to complete, and the teaching effect is poor. Contents of the invention [0003] The purpose of the present invention is to provide a buoyancy experimental device and experimental method for physics teaching to solve the problems of troublesome operation, poor visibility and poor teaching effect in existing buoyancy experiments, and the height and support angle can be adjusted. [0004] Above-mentioned purpose realizes by following technical scheme: [0005] A buoyancy experiment device for physics teaching, which consists of: a water tank 1, a square cup...
