Hi Unclejed
This is an excellent school project. It is not too sophisticated yet does everything he needs. Add a volume control at the back end of the op-amp and his project is done.
Good thing some listen to kids, other dictate to them.

or just change R1 on the second diagram to a pot...... that would do the trick as a volume control

Wow! So many circuits! Thanks a lot guys! now i'm having trouble choosing one😕 ! hehehehe! But it's better than having trouble designing the circuit! 🙂 I'm planning to build the one sent by minion though... but I think unclejed's circuit is nice too! 🙂 hmmm... what should I do? hehhehe
