Ms. Chang is trying to prepare her health class students for the onset of puberty. What should she tell the boys that they are likely to experience first

Ms.Chang could tell the boys that they might observe that their height is growing less at first but then it will increase to grow at a constant speed, the growth of ADAMS APPLE will also be observed and the boys might have shrill voice for a few days, there will also be the growth of hair in armpits and pubic regions. All that u should do is the experience and don't worry coz these all are the part of our growing stage.

hope it helps

have a nice day
