Data Streams: A crash course in data literacy using stream ecology
Level-up data literacy skills by practicing the "PPSTT" Framework for unlocking any graph's secrets. Students watch scientists model this approach & then try it on their own using multiple data types, including: the frequency of certain words in books, streamflow rates, and maps.

Lessons: 1, 2
In the Prompts step of the PPSTT framework, students determine the units on the graph, and how those units influence how the graph is read.

Mā te rauhiringa tātou e ora: Powerful Solutions: How do we provide sustainable energy to communities?
Learn about the energy all around us through a hands-on power generating lab, a web app exploring resilient energy mixes, and stories about Māui’s innovation. In Te Reo Māori, the unit title translates to "It is through positive energy that we thrive." This unit connects to Māori leadership in self-sufficiency and sustainability as inspiration for the future of energy engineering!
