Abstract:
Today, the Spectroscopy is not very well represented in the Romanian curriculum of Physics for high school. We are trying to develop a new method of understanding the phenomena that can be investigated spectroscopically. Our perspective begin with a short theoretical consideration of what light means for a Romanian high school student, as for example what is the role of the quantum transitions in the absorption and the emission of the electromagnetic radiation. We are intending to develop a question based curriculum in what concerns the Spectroscopy. So, we will try to find the answers to the questions as the following: What is light? How is the light emitted or absorbed? What are the quantum transitions? How can we detect the emission of radiation? What is spectrum? How can we obtain spectra with a classical spectrometer? How can we obtain spectra with a digital spectrometer? The students will notice the emission spectra or pattern of wavelengths (atomic spectra) emitted by different elements in the lab. Some of the challenges will be the verification of the Lambert-Beer law and the absorption spectra of a chlorophyll solution. We are trying to find out what type of monochromatic light are the green leafs using.
