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.
Speed and Motion | Posted in Physical Science
I am developing a lesson on speed and how weight can affect it. Does anyone have any materials and/or resources that could help supplement the lesson?
Implementing STEM in my classroom | Posted in STEM
I believe STEM is best implemented by allowing creativity, expression, and collaboration in the classroom. In all grades, but especially in the lower grades, I have noticed that students often learn best from each other. I would begin implementing STEM by designing activities around group work and/or students teaching each other.
In math, you can have students share how they got their answers step by step so that others can see and hear their peer's thinking and strategizing. In science, a great idea is having students work on group projects to "research" about the weather, water, and other Kindergarten TEKS. At the end of the week or lesson, the groups can share their findings with the class. I hope my ideas can help you implement STEM education in your Kindergarten classroom!
