Pippins find items on a checklist and take a picture of each one.
1) Divide children into groups
2) Go over checklist items with the children. Make sure they understand the task and the items on the checklist.
3) Show the children how to use the cameras.
4) Set a timer and send children out to find their items.
This could be a competition with the winner being the team that finds all items or finds the most items in a given time frame.
