Day 34: Mirror Mazes

The mirror maze is my favorite lab of the year and above is a pair of students’ work from today. Only a small number of lab groups get this thing on the first try.

Download my flat mirrors lab.

Kids are asked to get a laser beam from start to end going through at least three mirrors. Since this is year three with the lab, I can tell you the most frustrating part is the mirrors being silvered on the back. Kids establish a line where the mirror goes then have to slide the mirror forward so the silvered side is on the line.

Kids have a real love-hate relationship with the lab because I refuse to tell them how to apply the law of reflection, which they worked out in the first half of the lab.

This day last year: Last Class Tests (which reminds me, I never posted the test results here)
