Wild Journey • - You will be given an ‘Adaptations for Movement’ worksheet. • - Write in the adaptations that each species has for moving through its natural habitat. • Once you have finished the worksheet, you can begin your ‘Wild Journey’ • Get into groups of 5 or less • Each group will need: • 1x Wild Journey board game • 5x Species characters - use as your playing pieces on the board • 5x Species fact files - explains how your particular species is • adapted to moving through its natural habitat • 1x Rules sheet - read before beginning the game
If you land on your natural habitat square: roll the dice again. • If you land on your least suitable habitat square: miss a go!
