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.

Periodic Table | Posted in Physical Science

I'm looking for the best way to teach the periodic table structure to 6th grade. My experience has been on the 9th grade level, so I'm not real sure how to approach the subject.

Science in Kindergarten: What Does It Look like, Sounds like? | Posted in Early Childhood

I know there is lots of good science instruction happening in Kindergarten classes everywhere. I am hoping that some of you will share some of your planned lessons or lessons you want to make more NGSS like. New lessons ideas might be sparked! Ideas might be built upon. What books do you use to begin science investigations? What science investigations lead to writing? Lots of opportunities. :-)
