This 20 minute timer counts down silently until it reaches 0:00, then gentle beeping alerts you that the time is up. This is a great countdown timer for playing right on YouTube, or embedding in a Google Slide deck for use as an activity timer in social studies or science classrooms. You can embed the timer on the same slide as the instructions for the activity.
