Learning Science Concepts through Play | Posted in Early Childhood
What a wonderful way to include play in an inclusive setting. Play does help with those kinds of concerns about ability. Best, Arlene

Field Trips | Posted in General Science and Teaching
I am currently a student teacher in 2nd grade. We recently took a field trip to our city's Children's Museum. There were tons of different hands on activities for them to engage in over a broad subject matter. However, they did have some wonderful areas for science specifically. One part of our Children's museum has a place called "force works" where the children can use basically a large cauldron that rushes water through the entire exhibit! The children can see how the force of the waves move whatever the put in the cauldron.
In addition to this, there were areas where the children were able to see the life cycle of certain animals, specifically chicks.
These are just a few of the science-related exhibits there are, but it was a great way to get the students more engaged and interested in how science works!
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.
