Hi, This is Ella Fernandes and I am one of the Founders and I also created the online book check out. If you have not already, go to the website. Thanks - Ella Fernandes

Hi, this is Kaleigha and I'm an editor for Cecilia's Book Recommendations site. Here's a helpful tour of the website.

Cecilia Jones is doing a site that you can recommend books! I recommended some books and since I am a good reader, finally found some books I really like to read now. The best part was probably the Kid's Work. I got to read stories other people had created. I enjoyed the Secrets of WindClan series.Cecilia, wherever you are, that was awesome, and I recommend it to everyone. There is a book for everyone!

By the way on the STEAM lab page on schoology there is a link to a book recommendations site and it is really fun and interesting so I would recommen you go there. Because of that site, I found 3 books I want to read. And the best part is, they have an online book checkout, so I got the books I wanted the next day! So check that site out.

If you are doing the Final Project but don't have a Global Issue, go to the Project Idea and contacts page.

If u r talking about station 1 then I would suggest finding something in your own life that is very annoying and seeing how u could make it less annoying as I did.

# data[].attributes.body
That is not a station

# data[].attributes.body
station 5p

# data[].attributes.body
What station are you on?

# data[].attributes.body
I can't figure out which and how to enhance a product😥

I can't think of anything to do!

Here is a great article on how the laser cutter works!

How Does Laser Cutting Work?
Why lasers are used for cutting
Lasers are used for many purposes. One way they are used is for cutting metal plates. On mild steel, stainless steel, and aluminum plate, the laser cutting process is highly accurate, yields excellent cut quality, has a very small kerf width and small heat affect zone, and makes it possible to cut very intricate shapes and small holes.

Most people already know that the word "LASER" is actually an acronym for Light Amplification by Stimulated Emission of Radiation. But how does light cut through a steel plate?
How it works
The laser beam is a column of very high intensity light, of a single wavelength, or color. In the case of a typical CO2 laser, that wavelength is in the Infra-Red part of the light spectrum, so it is invisible to the human eye. The beam is only about 3/4 of an inch in diameter as it travels from the laser resonator, which creates the beam, through the machine's beam path. It may be bounced in different directions by a number of mirrors, or "beam benders", before it is finally focused onto the plate. The focused laser beam goes through the bore of a nozzle right before it hits the plate. Also flowing through that nozzle bore is a compressed gas, such as Oxygen or Nitrogen.

Focusing the laser beam can be done by a special lens, or by a curved mirror, and this takes place in the laser cutting head. The beam has to be precisely focused so that the shape of the focus spot and the density of the energy in that spot are perfectly round and consistent, and centered in the nozzle. By focusing the large beam down to a single pinpoint, the heat density at that spot is extreme. Think about using a magnifying glass to focus the sun's rays onto a leaf, and how that can start a fire. Now think about focusing 6 KWatts of energy into a single spot, and you can imagine how hot that spot will get.

The high power density results in rapid heating, melting and partial or complete vaporizing of the material. When cutting mild steel, the heat of the laser beam is enough to start a typical "oxy-fuel" burning process, and the laser cutting gas will be pure oxygen, just like an oxy-fuel torch. When cutting stainless steel or aluminum, the laser beam simply melts the material, and high pressure nitrogen is used to blow the molten metal out of the kerf.

On a CNC laser cutter, the laser cutting head is moved over the metal plate in the shape of the desired part, thus cutting the part out of the plate. A capacitive height control system maintains a very accurate distance between the end of the nozzle and the plate that is being cut. This distance is important, because it determines where the focal point is relative to the surface of the plate. Cut quality can be affected by raising or lowering the focal point from just above the surface of the plate, at the surface, or just below the surface.

There are many, many other parameters that affect cut quality as well, but when all are controlled properly, laser cutting is a stable, reliable, and very accurate cutting process.
