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."

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.
Gardening at school with young children | Posted in Early Childhood
I think you should do it in the spring considering that they have moved into a new location, meaning give it some time for them to settle in to their new environment. Regardless, doing it during the spring time will help the plants grow at a faster pace than any other season as during the spring, it isn't raining too much or it isn't too hot like the summer. I honestly find the gardening idea to be fascinating to both the students and the instructors as it shows students what living things like flowers, need in order to survive.
Learning Science Concepts through Play | Posted in Early Childhood
What a wonderful way to include play in an inclusive setting. Play does help with those kinds of concerns about ability. Best, Arlene
