• How can large amounts of data that have been collected over a long period of time (e.g., data related to climate change) be used to make predictions about the future?
Sample Tasks
1. Have students examine how cryptocurrencies use large server farms to collect, store, and mine information. Have students describe implications and consequences of these large server farms, including the amount of energy they consume.
2. Have students discuss how biometric data is captured and used to identify people using facial recognition software. Have students describe implications and consequences of the collection, storage, and use of biometric data by various companies and organizations.
3. Have students investigate the sources of data used to monitor the effects of climate change. Have students discuss how this data is being used to make predictions about future scenarios, and how these scenarios could inform the actions that people take now.
