Create your own spectroscope and explore the spectra of various light sources. This project helps you understand light's unique properties while having fun with hands-on experimentation. Ideal for middle school science fairs.
Different light sources will produce distinct spectra that can be analyzed using the spectroscope.

Cut a slit in one end of the cardboard tube.
Cover the opposite end with black construction paper.
Insert a CD at an angle inside the tube.
Seal the tube and ensure light can only enter through the slit.
Shine different light sources through the slit onto the CD.
Observe and record the light spectra produced.
Repeat with various light sources.
Draw conclusions based on the observed data.
You should observe different patterns of colors (spectra) for each light source, highlighting their unique properties and composition.
