First Day of School Science Activities | Posted in Life Science
Hello Lauren, A good beginning of the school year activity would be one that gets students thinking about the scientific progress to set the standard for the labs that would come for the rest of the year. Some ways to do this are setting up different stations that could be good for observation like, the characteristics of a flower, or even the way worms interact. You can have students make hypothesis based on their conceptions of the different stations. You can also do another exercise that can be done in perspective lab groups as a team building exercise. This consists of giving each group a handful of marshmallows and spaghetti sticks. They have to building a tower with the materials and see who's stands up the longest. Its quite a fun first day activity. Hope this helps!
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.
Learning Science Concepts through Play | Posted in Early Childhood
In the last couple of years, I have learned just how important play is to students. Play is just as important in the elementary grades, as it is for students preschool and below. I have learned that allowing students to play through STEM activities, allows them to work out their problem solving skills, monitor their emotions, and enhance their social skills. I believe that as teachers we need to remember that we can't hover. We need to allow our students to have play time. They need this time to enhance their skills in multiple different areas. One of my favorite play activities that students can do is through clay. I have seen so many different students play with clay, but I have never seen the same creation from a different student. This play can be as simple as having clay on the table and letting them create whatever they want, or it can be as complex as asking them to create different structures to hold something or withhold wind or water.
I really like the link that you added! I believe that it is so important to allow students to learn and socialize through play as well as different experiments, and these different experiments would be great in the classroom.
