Inquiry-Based Learning in Elementary School | Posted in Elementary Science
I believe that inquiry based learning is also extremely beneficial for students especially at the lower elementary grades. Like mentioned by others, this type of learning helps the students think for themselves. There are also different types of inquiry based learning, depending on how much direction you would like to give the students. If you are going to completely hand over the reins to the students this is called an open inquiry. In this inquiry the students will be in charge of coming up with a question/problem, procedure, and results/ analysis. This would be a great way to get the students to think creatively and problem solve. However, for the younger students it could be hard for them to come up with everything on their own. So, for this age group I would recommend a structured inquiry. For this, you as the teacher would come up with the question/problem, and the procedure for everyone to do. Then the students would have to analyze and reason as to why these things occurred. In my science methods class we did an experiment called "dancing raisins for our structured inquiry. We were given the question of, "Why do raisins, when added to a cup of sparkling water float to the top of the cup?" We were also given the procedure of putting five raisins in two cups with the same amount of liquid, one with sparkling water and one with regular water. Then it was our job to analyze why it was that the raisins floated in the sparkling water. I think that this would be a great idea of a structured inquiry for younger elementary grades. You can structure it, but still gets them thinking!
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 and Fairy Tales | Posted in STEM
This is a great idea to getting STEM into the classroom. Since the idea of STEM is somewhat a new idea i'm glad this shows how easily it can be incorporated. I also like how this activity can be used with many different books or novels so as a teacher you don't have to struggle to get a specific book.
