In science and health lessons, a scab forms when blood clots and dries to seal a wound and keep germs out; new skin grows underneath and then the scab falls off by itself. In safety and hygiene, do not pick scabs — it can let germs in and leave a scar. Phrases: «pick a scab», «the scab fell off», «form a scab».
