Do you have an observation scheduled and you feel like you want to wow your administrator(s)? This is the lesson for you; it includes everything any observer would want to see. This example can be adapted to any type of research project. Use this as your idea template or use as it.
As it is there are links for video hooks to grab your students, it involves having the explorers coming through time to be interviewed by your students.

I teach ELA twice and they were grabbing students in the hallway who were coming into my second ELA class to learn the same concepts and telling them that they were about to have a lot of fun today. Let your administrator hear that and you are golden, OR just use to motivate kids because that's the type of teacher you are!
