Solder up a circuit that flashes an LED and runs off a 9V battery.
That's the whole lab assignment. It's up to you to design a schematic, find parts, choose a construction technique, and make sure the customer (your professor) is satisfied. Feel free to ask questions, but you must demonstrate a working circuit by the end of class today.
If you need help soldering, read the comic book.
Here are some quick pictures of some of the student-built projects. The first student to finish the lab built an emitter-coupled multivibrator, which I like very much.
Another student built a free-standing artful one.
Most students built a simple 555 timer on a piece of perf board, which was a good solution.
Several students built their 555 timer circuits in the "dead-bug" style, which I appreciated.
One clever student produced this variation on a ring oscillator.
All great jobs.
