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.
Physics Songs | Posted in Physical Science
I like your idea of having songs for science! I feel like that is a great way to get students engaged and motivated. I know hearing song in school that pertained to learning helped me remember things. I can always remember the 50 states and capital song from 4th grade. Students I think would be more eager to learn the song without really realizing they are actually learning something along the way!
Project-based learning in a geology classroom | Posted in Evaluation and Assessment
I am a pre-service teacher, currently student teaching in a high school geology classroom. I would like to implement more project-based learning with my students. What are some effective strategies that you have found helpful in implementing a project-based learning unit? Also, how do you incorporate collaboration and self-assessment during a project-based learning unit?
Any comments or advice would be extremely helpful. Thank you!
