Day 1 Biodiversity

I am all over the place and really should have planned out a unit rather than isolated lessons. Yesterday's lesson was distinguishing between native and non-native species and introducing the students to the unit. However, not all of the students were able to even to figure out on their own what a species was. I ended up giving them a "do now," having them define what a native species was, watch the invasive species cane toad video, and then define what a non-native species was. Finally they did a quickwrite on their own (in some classes where there was time) differentiating a native from a non-native species. I feel like there was a sufficient amount of group work as well as individual work in this lesson. However, I am not sure how beneficial (however successful) this lesson was overall because it was too stand-alone and out of context. I really need to plan the unit.
