Using "The Threat of Invasive Species" TED-Ed video (4:45), students complete a WSQ-style write-a-long. The video can be found by searching the name on YouTube.
WSQ stands for "watch, summarize, question" and was developed by Crystal Krich for her flipped classroom (https://goo.gl/X8yPJ0). Using the WSQ method, the students take notes as they watch the video, they summarize their learning with some directed questions, and lastly, create either a "confusion," "discussion," or "curiosity" question to be addressed the next day.
My students watch the video as homework and the sheets are used to 1) make sure they watched the video, and 2) facilitate discussion the next day in regards to what they saw.
No key is provided on this version of the WSQ. Students should either have prior knowledge of, or be directed to look up, these vocabulary words: interdependence, exponential growth, logistic growth.
