Guest Speakers in the Middle School Classroom | Posted in Next Generation Science Standards

Aloha!

I teach 7th grade life science from 8:40a-2:20p and have about 8 guest speakers a year.

I have found that most guest speakers are willing to stay all day and repeat themselves!! I usually provide them with water and lunch/snacks.

I have found that most guest speakers do not provide notes for students to take, so I ask for their PowerPoint before they come in order to create a student handout. My students are much more engaged when they have something to follow and take notes on.

Go for it! Guest speakers enrich the unit and experience!

First Day of School Science Activities | Posted in Life Science

Payton,
I really like your idea of group work and discussion in the classroom. This form of teaching should be implemented in every grade level. It is a positive way where students can learn from one another as they are collaborating together on a group project. Different roles are divided between the students in each group allowing students to depend on one another. Discussion, in my opinion, allows students to reflect on what they learned that day, provide opinions about the assignment, and possibly suggest what they want to learn more about. This process makes students become active learners! I can see my future classroom using these learning strategies.

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.
