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.
Alignment summary( Target)
Lesson 1
Students will arrive at their Takeaway by observing a data set with varying data ranges and key words. Changing the timeline and adding in other key words can lead to changing the Takeaway and Trust of the graph.
Included resources

The Science of Craft: Building New Materials with Old Techniques
STEM is older and more expansive than you might imagine. Crafted materials, like knit sweaters and woven baskets, were our ancestors’ solutions to everyday problems. In this lesson, we learn the geometry and physics of traditional crafts, and explore how these technologies help us engineer new solutions for the future!
Alignment summary( Target)
Lesson 1
Students learn that the starting structure of mechanical metamaterials (yarn, reeds, beads) create patterns that help determine their crafted structures. The patterns in which yarn are knitted determine how a sweater looks and moves.
Included resources
3 lessons and 5 supporting media items.

Electric Crystals: Exploring how crystal symmetry can power everyday life

Crystals aren't magic, but they are amazing! In this student-driven, lecture-free lesson, students will do card sorts, build hands-on models, solve engineering design puzzles, and more! The whole experience is connected through a beautifully crafted comic and supporting videos.
Alignment summary( Connected)
Lessons: 1, 2, 3, 4
Students create molecular models of crystal unit cells, as well as geometric models of unit cells. They interpret how the two types of representations have different benefits and uses, and when each representation might be useful. They also draw connections between the two models and explore how the symmetries of the more detailed model constrain the allowed configurations of the coarser model.
