Ideas for school electronics Yr 10/11 projects?

[ynew]

HI, I'm new to the forum, so apologies if there are millions of these on here and I haven't found them yet, but....
I am a science/ physics teacher who is teaching a mix of electronics and physics to yr 10/11 students next year - have not taught electronics before and want to be prepared. Does anyone have interesting ideas for what to make in class that would suit this age group (ie 13 - 15yrs?) will be for students who have mostly never done electronics before... want to make the course as hands-on and fun as I can - any imput appreciated. Thanks in advance!

Interesting:

How about winding a coil and levitating a ball?
