In this science project, you will examine fingerprints from siblings versus pairs of unrelated individuals to figure out if general fingerprint patterns are genetic or random. . Have you …In order to deal with these large numbers more easily, scientists use a logarithmic scale, the pH scale. Each one-unit change in the pH scale corresponds to a ten-fold change in hydrogen ion concentration. The pH scale is theoretically open-ended but most pH values are in the range from 0 to 14.

A scientific question usually starts with: How, What, When, Who, Which, Why, or Where. Here are some characteristics of a good science fair project question: The question should be interesting enough to read about, then work on for the next few weeks.
