STEM as a "special"?? | Posted in STEM
[size=3][font=Trebuchet MS]Beth and everyone,[/font][/size]
[size=3][font=Trebuchet MS]You might also post this question on the STEM, earlychildhood and elementary [url=http://www.nsta.org/membership/listserver.aspx]email lists/listservs run by NSTA[/url]. You will add to the conversation and reach even more experienced NSTA members. The responses come to email instead of being archived on a platform but the conversations are just as helpful.[/font][/size]
[size=3][font=Trebuchet MS]My experience is with children ages 2.5-5 years old--also a wide developmental range : ) I haven't taught in your situation but over the years I've heard from others who have.[/font][/size]
[size=3][font=Trebuchet MS]They say that organizing the materials for 5 classes a day of children in grades K-8 will make your teaching time more productive. [/font][/size]
[size=3][font=Trebuchet MS]Think about what materials can be left out for subsequent classes. For example, having high shelves where I can quickly move trays of materials used by the 4/5s when the Twos come into the room is essential. [/font][/size]
[size=3][font=Trebuchet MS]Think about projects that can involve multiple ages at different levels, such as gardening. While middle school students are examining cell structure using microscopes, Kindergarten students can be planting seeds. The [url=Progressions Within the Next Generation Science Standards]NGSS Appendix E[/url]-Progressions Within the Next Generation Science Standards can help us make decisions about what to teach when.[/font][/size]
[size=3][font=Trebuchet MS]In keeping with research that shows children learn over time, plan to teach a concept over weeks and months, not just one week, especially the K-2 students.[/font][/size]
[size=3][font=Trebuchet MS]I hope your colleagues in the grade level classrooms can meet with you to see how you all can collaborate so science-technology-engineering-math doesn't become isolated from the rest of the children's learning.[/font][/size]
[size=3][font=Trebuchet MS]Best wishes for a successful program![/font][/size]

Teaching Earth Science for the first time | Posted in Earth and Space Science
I don't remember where I got this (possibly Facebook - or here!) but I use an inflatable globe and throw it out to a student. The student catches it and tells me how many of their fingers are touching water. They then share something about themselves and toss it to another student. Tally up the number of fingers touching water for each student and then calculate the average at the end It should be close to 70%, the amount of the planet's surface covered with water.
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.
