Explore buoyancy at home. Spring scales can be used in experiments Describe your experiments and take photographs.

Hang a mug from a spring balance, determine its weight, place half of the mug in a vessel (pan) with water, determine the weight of the mug, then place the mug completely in the ox, determine its weight. P = mg. The more part of the mug you lower into water, the less its weight, respectively, the greater the buoyancy force.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
