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.

Science Trips | Posted in Informal Science

There was a great science field trip that I got to observe in my students teaming called Days of Taste. It was a three day process that followed the process of a well-designed experiment and combined the subject of health and good eating all in one! A nearby farm partnered with the school to come to the school the first day and introduce the topic while giving the students different types of demonstration powders to get their taste buds flowing and practice prediction and data collections. The second day the kids went to the farm to see the process of making milk and cheese and harvesting the crops that they are growing. The third and final day, the farm comes back to the classroom alongside of a local restaurant that benefits and works with the farm to finish the investigation process and confirm or reject hypothesis. Then they get to use the foods that they learned about to create a salad that would be the best fit for your health. The combination of incorporating science, health and arts with they creation and display process works out great for the students learning benefits!

inquiry Based Lesson Plans | Posted in New Teachers

Hi Stephanie, 

There are a lot of ways to incorporate inquiry into a second grade classroom.  If you aren't very familar with inquiry, a good place to start is with this article from Science and Children (The Many Levels of Inquiry) that discusses the four types of inquiry. It gives some sample suggestions of how to use the four types of inquiry in your classroom.  

From there, I would look my curriculum and decide what types of inquiry I would want to use as I am teaching. What types of topics are you going to be covering in second grade?  What information do students need to know in third grade?  Knowing that information better helps in planning.  If you your state has adopted NGSS and you are unsure, you can always start by looking at the NGSS standards that can be found here. 

Another resource you might look at is an ebook, A Year of Inquiry, that the Learning Center has at a nominal fee.  

Respond back and we can brainstorm together.
