Do you need to buy physics experimental equipment in junior high school?

There is no need to buy physics experimental equipment in junior high school.

You will see in school that it is boring to repeat school experiments at home with professional equipment, which can't exercise children's innovative thinking ability. It is best for students to look for daily necessities instead of professional equipment according to the principles learned in school, and reproduce the phenomena and principles seen in school, so as to develop children's intelligence, improve their hands-on ability and innovation ability, and improve their IQ in physics.

Commonly used physical experimental instruments are:

(1) Basic measuring tools and instruments, such as meter ruler, vernier caliper, micrometer, balance, spring scale, metronome, dot timer, thermometer, measuring cylinder, barometer, teaching ammeter, voltmeter, universal ammeter, oscilloscope, signal generator, etc.

(2) General instruments, such as projectors, film machines, magnetic teaching boards, vacuum pumps, physical supports, power regulators, etc.
