Having an Awesome Time Doing Science

September 10, 2009

I noticed that an two-day old highlight on a paper looked richer than new highlights, even though the highlighter was the same.

The experiment: Highlight a block on a piece of paper. Cover half the block, leaving half exposed to the sunlight and evil fluorescent office lighting.

Controlling for: Effect of time on highlight colour.

Observation: Covered half is lighter than half exposed to light.

Conclusion: Lighting interacts with highlight colour.

Threat to validity: What if air flow is the real cause of highlight colour change?

Future research: Does it matter if the light is fluorescent or sunlight?

    To test your air flow threat, I suggest doing another controlled experiment with overhead transparencies (available in the copier room) to allow for sunlight and limit airflow.

    high five!

    Scotch Tape … and paper is pretty porous so you may need to cover both sides of the paper 🙂
