The lecture began, and the girls in our class felt embarrassed when they saw the title "Special lecture on adolescent health education in grade five". As soon as the boys in our class saw the word "adolescence", they began to dream. The theme is "The Secret of Growth". Seeing the word "secret", you must be curious to know the secret of growth, right? Then follow my introduction into Mr. Huang's lecture!
At the beginning, Miss Huang asked us three interesting questions:
1. When you exercise in physical education class, you will find several classmates sitting next to you. Why? Xiao Ming's voice has dropped gradually recently, and he has grown a little beard. What's going on here? Xiaokang saw red blood on Xiaoli's chair at the same table. What happened to Xiaoli? The students were very active and answered the questions one by one: 1. Because those students are menstruating, they are not suitable for strenuous exercise. 2. Because Xiao Ming begins to develop, he will grow a beard and his voice will slowly sink. Xiao Li is menstruating. The girls listened to the students' answers one by one, and their faces gradually turned red like red apples.
Next, Mr. Huang briefly described the puberty development time of boys and girls through slides: boys 1 1 over; The girl is about 10 years old. Then I talked about the second characteristics of adolescent men and women: men show long beards, prominent Adam's apple, thick bones, low voices and so on; Female breasts are enlarged, pelvis is wide, subcutaneous fat is rich, and her voice is sharp. Teacher Huang also showed us a video of "menstruation". After everyone watched it, the big conference room was full of vomiting.
Finally, Mr. Huang left the meeting room with the applause of the students and ended the lecture. This lecture let me know how to take care of my body.
