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.

Field Trips | Posted in Elementary Science

Hi Rochelle,

Field trips can be a great way to engage students with science.  Our school asks us to include one field trip for each class.   Local museum and other educational institutions are a good place to start.  I've taken my chemistry students to a local aquarium the past two years where they have a hands-on program on water quality in the aquarium as well as a local waterway.  Biology students do a program at the natural history museum.  Environmental science students have done field studies at local parks, a waste treatment plants and composting facility.  This year we began the school year with a service project.  Students were bused to a number of location organizations, parks and institutes to do some volunteer work, but also to learn about the needs in the community.  A couple groups went to a local nature park and another to an arboretum where they both helped in planting and weeding and also learned some of the science behind maintaining a healthy ecosystem.  Think about what resources are available in your area and then make some phone calls.
