This learning resource focuses on understanding digital footprints, specifically distinguishing between active and passive data. It presents a scenario involving a nostalgic post about a lemonade stand from three years ago as a case study of how online activities can persist over time and impact future opportunities. Through structured activities, learners identify data points included in their posts, contemplate how others might interpret this information, and discuss the permanence of digital content. The resource emphasizes the consequences of online presence, particularly in professional contexts, encouraging students to reflect on the long-term implications of their digital actions.
