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

Last school year I was able to bring Marine science students (3 classes ) to coconut island in kaneohe, HI.  THey have a wonderful lab set up where students are able to view plankton under high magnifications as well as an opportunity to sort therough a sample of ocean into the many species. They also got to see the shark enclosures.    The students said it was a life changing experience.  Our 9th grade biology students were able to go to Papahana kuaola also in Kaneohe where they were able to work in the taro patch and collect invasive frogs fromt he stream.  

Now virtual trips may be available as well to be able to explore over seas.  THe feeling you get traveling with your classmates is second to none.

The Rock Cycle | Posted in Earth and Space Science

Hello!  I am a student teacher and am making a lesson plan for the Rock Cycle.  I have a couple a resources for the lesson plan itself but, I am having trouble with the length of the lesson plan. I tend to make the lesson plan longer so the students have more time to explore and have opportunity for group discussion. This a 6th grade class and is only 45 min. How can I still have the hand-on activity within this period of time? Any suggestions?
