Oops! I Made a Dye
The teenager that accidentally invented the first synthetic dye
Who is William Henry Perkin?
This particle jumps between energy levels and creates colorful light
What's an electron?
Part of the atom living in the nucleus and has a positive charge.
What is a proton?
This kind of color mixing happens on a screen when red and blue light combine to appear purple.
What is additive color mixing?
This word describes what happens when improving brightness makes waste or water use worse.
What is a trade-off?
Dye color that Perkin discovered
What is purple (mauve)?
This particle is released when an electron drops to a lower energy level
What's a photon?
Name of the speedy, negatively charged particle that orbits the nucleus of an atom.
What is an electron?
This kind of color happens on a CD when rainbow colors appear because light is separated by wavelength.
What is structural color caused by diffraction?
This is the problem when a student says, “My design was better because it looked nicer.”
What is not having measurable improvement?
Chemical that Perkin originally was trying to make in his experiment
What is synthetic quinine (to treat malaria)?
Tool used to analyze the spectrum of light, you created one for this expedition.
What's a spectrometer?
Neutral particle that also lives in the nucleus and keeps the atom stable (sane)
What's a neutron?
This happens when an excited electron falls to a lower energy level and releases a photon.
What is emission?
This is the design problem when dye concentration, soak time, and material type are all changed at once.
What is having too many variables?
It made purple dye cheaper, easier to produce, and longer-lasting
Why was Perkin’s discovery such a big deal for the fashion industry?
Part of the electromagnetic spectrum that our eyes can actually see.
What's the visible light spectrum?
Name of the core of the atom.
What's the nucleus?
This usually explains why a green leaf or dyed fabric looks green in white light.
What’s how objects absorb other wavelengths but the green one?
This is why testing a prototype only once is weak evidence.
What is scientific reliability?
Sea creature used before Perkin’s dye to make purple
What are sea snails?
Part of the molecule that reflects the color for us to see it.
What's a chromophore?
Number that give element its identity. It is equal to the number of protons in any element's nucleus.
What is the atomic number?
This is why fireworks and dyed fabric can both show color, but through different science.
What is absorption vs emission?
This is what is wrong with the statement: “This design worked because it was more beautiful.”
What is that the explanation is subjective and not based on measurable scientific evidence?
