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.

Teaching Science to Kindergarten in a Short Time Frame | Posted in Early Childhood

Definitely start integrating science into everything else you do! That could mean a weather conversation during your morning meeting, reading a science content filled story during your read aloud time, having them write about a science topic, etc. Any time you can double up subjects, definitely take advantage of those opportunities!

Inquiry-Based Learning in Elementary School | Posted in Elementary Science

Hi Kevin! I am currently taking a undergraduate course called "Methods of Teaching Science" and we also have a major focus on inquiry-based learning. Personally, I believe that inquiry-based learning is great for students because it gives them a chance to think for themselves instead of merely being told an answer. Furthermore, science is an ongoing investigation of the natural world so even professional scientists are in a continual process of reviewing and asking questions. One way to incorporate this type of learning is to follow the 5E model (Engage, Explore, Explain, Elaborate, Evaluate) which easily aligns with Next Generation Science Standards. I suggest becoming familiar with both of these, if you are not already! I cannot think of any cons of introducing inquiry-based learning to lower elementary grades. Journal Article that addresses your question: https://learningcenter.nsta.org/resource/default.aspx?id=10.2505%2f4%2fsc17_055_01_18  I hope some of this is useful to you!
