Seeing the Signs: Color and Viewing Distance

Medium
Seeing the Signs: Color and Viewing Distance | Science Fair Projects | STEM Projects
Have you ever been driving and seen a sign you couldn't read? We're testing to see if the color of the text on the sign makes a difference in how far away you can read it. We'll use different colors of spray paint on metal sheets and measure how far away people can read them.

Hypothesis

The hypothesis is that participants will be able to view signboards with white or yellow text and a dark green background from a further distance, as compared to red or blue text.

Method & Materials

You will spray paint metal sheets with green paint, then use stencils to spray paint words in different colors. You will then measure how far away people can read the words.
You will need metal sheets, spray paint, stencils, cardboard, students, a ruler, a paper cutter, a football field, a measuring tape, and an assistant.

Results

The results showed that the students were able to read the white and yellow-colored words from a farther distance compared to the red and blue words. This proves the hypothesis correct.

Why do this project?

This science project is interesting because it tests how color affects how far away people can read a sign. It also shows how important it is to have signs with good color contrast in order to keep drivers safe.

Also Consider

To improve the reliability and accuracy of the results, a larger sample of colors should be used. This science fair project may also be repeated with participants of different age groups.
