My students LOVE talking about aliens; whether they’re out there, what they might look like, and how we might communicate with them. We started off Lesson 10.3 with the Drake Equation activity to get my students thinking critically about the future and the possibility of intelligent life beyond Earth. I love using the Drake Equation activity because it can be the catalyst for a moment of revelation for students who have never considered the implications of the sheer size of the Universe for finding alien life.
I begin the lesson by posting 10 statements about the future around the room (feel free to download the template I created). Students write their name on the statements they believe are likely true. The statements range from, “Human-induced climate change will cause the extinction of our species” to “Technologically-advanced aliens will colonize our planet (and we’ll all die).” We discuss the statements with the most positive reactions to draw out why students have arrived at their conclusions.
After this discussion, I break the class up into six groups and give them each a step in the Drake Equation (as outlined on the activity worksheet). They have two minutes to decide on their response as a group. We then run through the activity with each group reporting their decision while I write our estimated chance of finding alien life on the board.
The last time we did this activity, my class ended with a number less than one, indicating that we don’t believe we will find intelligent life on another planet. We used this to consider our initial ideas about the future and to discuss whether anyone had changed their mind about versions of the future involving intelligent life beyond Earth.
