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
