I created this worksheet and scavenger hunt for an all girls STEM-careers camp. The girls were ages 6-12, so we completed the worksheet together, and did the scavenger hunt in two groups based on age. The clues for the scavenger hunt will probably need to be rewritten based on the locations you have available. Additionally, the answer to the first question on the worksheet is "girls rock", and this may also need to be changed in a typical classroom or enrichment setting. Overall, this is a great activity to introduce children to the idea of cryptography. Many of my campers really took off with the idea and wanted to learn more and improve their skills.
