The Drake Equation | Posted in Earth and Space Science
The Drake equation is not directly used by scientists in their research. Rather it is often used when talking about life in the universe to non-scientists, such as in astrobiology courses, as James mentioned. One of the keynote addresses I sometimes deliver is on astrobiology, and I discuss the Drake equation quite a lot, as it relates to many fascinating topics regarding the development of life in the universe, where we would expect to find life, and how common we might expect life to be.
The purpose of the Drake equation is not to give a precise answer to that fundamental question -- How many technological civilizations are in our galaxy? -- but to form the basis of discussions by presenting various types of information that we would need to know, if we wanted to answer that question.
So basically the Drake equation is a statement that "stimulates intellectual curiosity about the universe around us, for helping us to understand that life as we know it is the end product of a natural, cosmic evolution, and for helping us realize how much we are a part of that universe." (https://www.seti.org/drakeequation)
What the equation and the search for life has done is focus science on some of the issues concerning life in the universe, specifically the development of life starting with chemical processes, the development of multi-cellular life, and the development of intelligence.
Science in Kindergarten: What Does It Look like, Sounds like? | Posted in Early Childhood
Robin, your children might be interested in participating in a citizen science project. See SciStarter for a list of projects, some that even preschool classes can participate in.
First Day of School Science Activities | Posted in Life Science
I teach only science, so for me, I get the kids for a short time and I am looking to make it pop. In elementary classes, I start with procedures or expectations but I weave that into an inquiry/discovery lesson. Mostly I use units from the Picture Perfect Science books by Karen Ansberry & Emily Morgan. They include lessons on discrepant events like the jumping beans for 4-5th biology (where students learn that not everything is as it seems at a glance) or "Earthlets" where students learn the value of piecing together all the information that they discover. I've used their lesson on the learn'd astronomer or Rachel Carson, "a sense of wonder" in both cases to introduce in a soft-start way that science is more than "doing". It includes pondering, wondering, ruminating over how amazing creation is...and helping students to place themselves inside that story as active participants in the science journey.
