Extract from the Official Bulletin:
2nd: Health - Medicines
Practice an experimental approach to determine the concentration of a species.
The Universe - Stars
Emission and absorption spectra: continuous spectra of thermal origin, line spectra.
Emission or absorption lines of an atom or ion.

1st S: Observe - Colors and images
Color, vision, and image
Practice an experimental approach to illustrate and understand the concepts of object colors.
Distinguish perceived color from spectral color.
Sources of colored light Different sources of light: stars, various lamps, laser, LED, etc.
Distinguish a polychromatic source from a monochromatic source.
Colored materials Practice an experimental approach to determine the concentration of a colored species from a calibration curve using the Beer-Lambert law.

1st STI2D/STL: Common core - Habitat - Lighting
Light sources.
Wavelength, color, and spectrum.


Introduction:
The new generation of CCD detector spectrometers allows for real-time recording of any spectrum across the entire range of wavelengths.
Optical fiber provides great flexibility for capturing any light source.
The cuvette holder and filter, removable without tools, open up the field of manipulations towards the study of filters and chemistry.
All these technical advances, combined with great ease of use, make them essential and highly versatile tools for carrying out numerous experiments from 2nd to 12th grade.
