I have not had time to do my lesson that was created this summer as we are not at that point in the curriculum. However, I do find that I talk about my experience quite a bit in the classroom as I'm teaching. I also put my you tube address on the board and suggested that they check out what I did this summer.... I have 97 Hits!. My students will come into the room and tell me that they checked out the video -- I then ask them if they understood it, and the reply is always no. I guess that I will have to make another one where the students have more models of what the Raman Microscope does and an example of what has been done with Ranjith's research to help the students understand it better.
I also have implemented science notebooks in a different way than I have in the past. I'm still not there yet - in other words, it's not where I would like my students to use them but we are getting started. Students did not reflect after they did a lab or an assignment before this, now I am requiring that they do after each unit, I think that, to some of them at least, this reflection is making science more meaningful to them.
My next step is the blog -- I will introduce that next , then the lesson. I hope that if I bring up this experience throughout the year, students will understand that things that are learned are built upon and used in many different ways.-- Also, with me getting turning 50 this year, maybe they will see that you are never too old to learn new things.

Notice that each of these "dots" have boatloads of other dots- now we'll look at one of them close up. Remember, this is the eye of a fly- think about how small this is!
This is a picture from the electron microscope - these dots are on one of the dots of the eye of a fly. I can't believe the detail! I know, "Calm Down Mrs. Neagle" - it's just that I am truly in awe when I think about what we can do and see now with our current technology.

I finally was able to upload my video on you tube and have also copied onto this blog - check out Ranjithe's Lab with the Raman Microscope.
While John was working on that lab, I ran down to Ranjith's lab -he was not there . I want to get the results and compare them on my computer - so that I can work on my presentation. I need to make sure that I have analyzed the data so that I can come up with some conclusions or redesign.... (note steps of the Scientific Method).
Hopefully, I will have the powerpoint presentation posted to the blog this week so that you can get a better understanding of the lab that I've been working in.

This week, we were asked to create our lesson plan,(check) add to the blog (doing it now) and create a video that we will put on you tube and later on a link to my website ( which I haven't made yet)
We attended a meeting on Monday that took the whole day - it was pretty interesting on Problem Based Learning (or PBL for short) -- It links local businesses with schools to help solve problems that they are having with something that they are manufacturing or plan to manufacture. The students are to brainstorm and try and solve the problem. It was fun but all of us felt that our time could have been better served working in the lab or working on the products that WE need to produce in only 2 1/2 weeks!
Tuesday we had another meeting but then I spent my afternoon creating my lesson plan - I am very excited about trying it out - yes, you current eighth graders are my guinea pigs for trying it out but I think you'll like it :) .... anyway, Mr.P and I then went with Prof. Morse on a presentation fo fiber optic history -- very interesting stuff - especially thinking about the fact that fiber optics were make in 1913 but really not utilized for another 60 years -- now, almost 100 years later-- look at how much we use them! In TV's. Cell Phones, Ipods, Xrays, etc. Pretty awesome stuff!
Today we went to 2 labs -- pictures will follow. My lesson is on identifying White powders using different equipment or different tests and determine what the Mystery white powder acts like.
We looked at several white powdery substances under the electron microscope - can you tell what they are?
Asprin, Baking Soda, Baking Powder, Cornstarch, Powdered Sugar (not necessarily in that order)
All White powders and yet .... They look so different up close!
The other lab was my lab with the Raman Spectroscopy Microscope. I used the portable one today. I got all the data that I needed with it. I will be needing to get the actual fingerprints so that I can show them in school. My students will have to figure out which is which, just like the above pics.
I spoke with Ranjithe about videotaping him tomorrow -- hopefully, it will go well and I can post it by Friday. He said that we can do that tomorrow afternoon.
All in All, it has been a good week, busy but productive. I feel much better having a plan for my poster and having my lesson plan done.. TTFN (Ta Ta for Now)

Using discs -, we put a film on the disc and put it in the centrifuge to spread it out evenly.
We then put it on a hot plate so that we could dry it on.
We put this disc into a machine which etched out the design.
After we did that, we put it on the hot plate again.
We then removed the film from the spots that were etched out.
We checked the disc through the microscope and checked out the design on the film,
Then cleaned our mess.
On Monday we were to meet early in the am with Helen Fawcett so that we could be introduced to our new lab. We got there on time but she was not there.
Assignments this week, continue with blog, make a 5-10 minute video and up load it on You tube and begin lesson plan.

We have to present our posters to 2 different groups - once to the group at BU and then to the group at NEU . I was under the impression that we were creating a poster that can be used in the classroom that brings in the experience that we had this summer -- and for me - the different experiences in 4 different labs. I asked about this because the examples of posters that were shown were so dense with information, that I did not think that this would help my classroom and their understanding of what we did this summer. I was told that the poster should be geared towards my colleagues- not my students and be at the quality where we would present this information to the NSTA. I think that I am going to make my poster with some understanding of what is being done in the lab but in a more simplified version so that my students can see what is being done in the "real world". A mix of the 2 worlds....
Anyway, this week, we were introduced to our new lab and it looks pretty neat. We have a little guidance with the equipment but at the same time, we can use and experiment on different substances. I am thinking about the standards and where this information will fit and I keep thinking about the properties of matter unit and how some substances react to others. This will lend itself to a poster too. Different white powders, able to identify them on the machine and understand which reactant to produce a chemical change to the substance. I am looking forward to starting my tests on it -- We are planning on being in the lab All day tomorrow -- no meetings to attend to so that will be alot of fun.

Yesterday morning, we had a meeting with one of the liasons from the RET project to discuss how we were progressing in our lab....
Well, the person that we were working with was on vacation and we were asked to devise a system to feed the solution evenly to the nebulizer but not sure what to do from there - waiting for an answer as to whether we could purchase the part and start to build and test our prototype. We were then met by Leah, the lab liason and she said that there was a project originally planned for us but it was outsourced to a co in Tennessee - so we were there to observe and help as needed - but no longer a set plan.
We went to lunch, came back and Leah introduced us to another gentleman and his lab on looking at the waves of different types of light -- he showed us how the machine worked and then left. Mr. P. and I played for a while - testing out my flashlight, the flash on a camera and such and then got bored and went back to our office - again with no direct plan.
We were met again by Helen - the RET project liason and she said that we will be going to a different lab that really could use our help-- YEA!!! We will be testing out a new machine and comparing the results with a much larger machine and giving them feedback on the new equipment. We will be testing the light waves of ecoli -- this is a really good test because they have been able to see that different strains have different light (color) - which coincides with properties of matter. It will be helpful in the doctor's office because instead of him saying,"Try this medicine"- he will know immediately what will kill that bacteria and give you the right stuff.
Hopefully, we will stay in this lab for the rest of the time so that I can post on the progress.

1. This photo shows the set up of the lab. There is a glass tube where the silicon will be deposited and it's sprayed on into the flame by the device in the middle with the knobs. The devise with the knobs moves to the right and left as the glass tube turns to ensure an even flow of the material
3.This is the beginning stages of the experiment or test-- The silicon is mixed with oxygen which causes it to burn and deposit the soot onto the glass tubing. Another note -- notice the dark line in the center of the flame ; it was important to make sure that this was there but not too high up onto the tube. I think that this is a cold spot and you want to ensure that the hottest part is at the tube.

This is a 6 week course where teachers have the opportunity to work in the field and learn about how Science is being used in the real world.
This course is on Biophotonics ( Bio -- what?!...) - Essentially it's looking at life science (biology), general science ( scientific method) and engineering to enhance things like X Ray machines, find Skin Cancer with Lasers or Identify diseases with light.
I thought that this would be truly exciting so I signed up and got in!
We were partnered with a lab team and another teacher (the other teacher is a pretty cool guy - Mr. P- that teaches Physics and Astronomy in Weymouth). My lab is on "Scintillation measurements for high resolution X-Ray project lab"- the Lab Professor is Ted Morse.
I was given two assignements for the first week -- 1. learn as much as you can about Fiber Optics and 2. learn as much as you can about Total Internal Reflection or TIR for short.
I have to say that there is a big learning curve and I have a lot of catching up on reading and understanding of these two topics -- I guess my summer reading isn't as light as I thought it would be.... More to come, me and my lab partner's project this week is to devise a way for the Silicon solution to spray evenly onto the glass tube... I'll explain with pictures in my next blog.
