Seventh graders discover that the few seconds between pressing power and a ready screen hide a careful sequence, as the computer wakes its hardware and loads its operating system, then put the steps in order.
Students will be able to…
You press power and a few seconds later the desktop appears. A lot happens in those seconds to wake the machine. What are the steps, in order?
Project this and put the steps of a computer starting up in order — tap each one from the power button to the ready desktop.
Tap any phase to open the teacher moves and student actions.

Preview the three formative checks. Tap “Sample answer” to see what mastery looks like — hide them before you print for students.
Have students draw the steps from power to desktop, label each one, and mark where the operating system loads, so the hidden sequence becomes clear. A printable startup worksheet is in the Computer Science library.
Tap a card to flip it, then rate whether you knew it. Built from this lesson’s vocabulary.
