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.
STEM programs | Posted in STEM
STEM stands for science, technology, engineering, and mathematics. I don’t believe that this should be thought of as a new concept because we teach students science and math almost every day, and they encounter these subjects every day. Students walk outside, and there’s science all around them. Students use math every day to pay for drinks or food, simple addition or subtraction, and counting. They use technology every day too with cell phones, laptops, Ipads, etc. These topics aren’t hard for the students to learn because they already know things about them and encounter them every day. We just need to turn them into an educational teaching that promotes higher thinking.
I would implement STEM within my class by having my Kindergarten students work on simple yet, challenging experiments. For example, my students need to build a bridge for 21 elephant counters. All of my students know how to count to 100, and they all know how to make and build things like bridges, towers, cutouts, etc. Now they need to use trial and error to see if what they think works (science). They would then need to count how many elephants they can fit (math) on the bridge they built (engineering). In the end, the teacher can help the students record their finding on video or add the audio to a picture using an Ipad (technology).
Science Trips | Posted in Informal Science
Pam, I really like your idea of visiting a local university with students! I know from experience that children at this age look up to young adults, which provides a much greater chance for the students to listen! A great idea for them would be to visit the greenhouse (in the university has one) or, doing something even in a science class, or EL ED methods course.
