Single palm split bricks, steel balls to wear coins ... this teacher's course, not ordinary!

In the physics class of Mr. Liu Huadong, Henan Huaiyang Middle School, "single palm split bricks", "steel balls wears coins", "bulb nails", "A4 paper to mention boys" ... These "peerless martial arts" that sound like are all very He directed his classmates to understand the experiments of physical principles.

In order to make students fall in love with physics

Middle school teachers show "Peerless Martial Arts" in class

With a "snap", a female classmate split a brick at hand on the podium. The students exclaimed and the applause sounded warmly. This scene occurred in the physics class of Liu Huadong, Huaiyang Middle School in Henan.

Later, Teacher Liu's explanation began: "Broken bricks are not brute force, but through the" momentum theorem ', the brick raises slightly and hit the table with bricks. Big. This force can easily exceed its tolerance and split bricks. "

In order to let students fall in love with physics, Liu Huadong will try to ponder some interesting experiments when preparing lessons and integrate them into their own teaching.

For example, when Liu Huadong talks about the amount of motion and collision, it will allow students to experience split bricks and steel beads to wear coins; when they talk about friction, let students go to the sports field to come to the tug of war; Essence

As a result, such as the "arched principle", "cutting point stress" and "stretching line stress", such as boring and abstract nouns, become emotional in Liu Huadong's class in class, boring, boring, boring, boring The knowledge of physics class becomes vivid and lively.

Teacher Liu Huadong guided students to use the principle of leverage to "tear apples".

In the relevant principles of use force, an A4 paper lifts 80 pounds of heavy boys.

The students found that many experiments that sounded impossible were displayed in front of Teacher Liu in the "magic form", and never knew what "peerless martial arts" would show in the next section of physics class. "Physics is a boring course, and he will always find a way to make these boring content interesting."

Outside the school he is the popular science knowledge promoter

Put your wings for children's "Scientific Dreams"

At school, Liu Huadong is a good teacher. When he goes out of the school, he is even a promoter of popular science knowledge.

It is understood that Liu Huadong is also the head of the Rural Middle School of Huaiyang County, the Science and Technology Volunteer Service Corps of the China Science and Technology Museum Development Foundation of the China Science and Technology Museum and the science and technology volunteer of the Henan Science and Technology Volunteer Service Corps. Relying on the "Science and Technology Museum", he often organizes popular science popularization activities such as popular science lectures and innovation education, planning scientific experiments, and inserting wings for children's "scientific dreams". This year, Liu Huadong was selected as the "Star of the Year" of the National Science and Technology Volunteer Service.

Liu Huadong said that he liked to dismantle home appliances from an early age, so he fell in love with physics. When he was a child, he had a dream of becoming a scientist. Although he failed to become a scientist, as a teacher, he hoped to cultivate future scientists.

"I hope that through experiential classrooms, the esoteric physics is easier to understand, students prefer physics, and then apply what I have learned. I hope that the students I teach will be better than me. In the future, I can become a talent for trusting and reliable in the future! "

Liu Huadong does popular science for children.

Praise for Liu Huadong!
