Build a door bell


Do you know how gears, cranks and wheels work? You can find out by making a hand-operated doorbell for your room.  Once the doorbell is finished, it can be painted or coloured and then screwed onto your bedroom door. This is a creative making kit for curious minds.

Koa Koa project-based learning kits encourage kids to ask questions, experiment, be creative and understand how things work!
