Core Skills Analysis
Science
- Will identified that visible light is part of the electromagnetic spectrum and can be separated into colors using a prism.
- Will described how each color corresponds to a specific wavelength range, linking wavelength to energy.
- Will explained the three main types of spectra—continuous, emission, and absorption—and what they reveal about the source of light.
- Will connected the concept of light spectrums to real‑world uses such as analyzing star composition and identifying chemicals.
Tips
To deepen Will's understanding, have him construct a simple spectroscope with a CD fragment and a cardboard tube, then record the spectra of different light sources (incandescent bulb, LED, sunlight). Follow up with a research project on how astronomers use spectral lines to determine the elements in distant stars, and ask Will to create a visual poster that matches colors to their wavelength ranges. Finally, integrate a short writing reflection where he explains why the spectrum is a powerful scientific tool, reinforcing both content knowledge and communication skills.
