You could start the activity by talking about the importance of attaching a fuse first. Or maybe setup the batteries with a fuse attached beforehand.

Subject: rechargeable batteries

Hello colleagues,



I have been told that rechargeable batteries are not suitable for "build a circuit" activities with kids because they can  get hot when short circuited and/or dump their entire charge at once.



But I'd love to get away from using disposable batteries in our school programming, where we have kids building "dexterity testers" (in the style of the game Operation).



Any suggestions or experience with this?



thanks



sandy
