Hi, I run wonderful learning Adventures covering everything from Greek Mythology to Seventeenth Century Piracy to the Story of the Thames (including a boat trip and/or Mudlarking on the foreshore) to Cool Shakespeare to creating one's own exquisite collection of coleoptera without hurting a single beetle... these are adaptable to all ages. My website is geared towards 6-12 yr olds, but I also give tours and lectures to adults, so your 12 and 14 year olds will absolutely NOT be talked down to!
