- You will be given an „Adaptations for Movement‟ worksheet.
- Write in the adaptations that each species has for moving through its naturalhabitat.
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
