Find and compare
For the first round, an adult will be the ‘Nature Guide’ and find something in nature to pick up and show to the group. The children then have a designated amount of time (for example 60 seconds) to search the space for an item that is similar to the item that the ‘Nature Guide’ has. Whoever has collected an item that is the most similar will be the new guide and have a short amount of time to find something new that they will then present back to the group. The game then repeats.
