Making Musical Instruments | Posted in Informal Science
Thank you for sharing this post. I have a science unit that I do with my preschoolers, kitchen band, which is experimenting with sounds found in the kitchen. Never thought of using a carrot to make an instrument. It's intriguing to notice that you can make musical instruments out of almost anything. Thanks again for sharing.
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.
Increasing Student Engagement in Science Lessons | Posted in General Science and Teaching
I am a first semester student teacher in Houston Texas. I have to say that I love using Kahoots. I remember using them in many of my college courses which made it fun and exciting. Recently, my cooperating teacher and I had a training where we learned about another program that is similar to Kahoots which I think you might like as well. It is called Quizziz. The difference that I found interesting was that when using Quizziz, the teacher could assign the students "homework." This would allow the students, if they can, practice for tests at home on their own time.
We tried it out just today in the classroom as a quick test and the students absolutely enjoyed it. At the end of each class, all the students had asked if we could use this more often for future tests.
