Termite Handedness Summary: Animal behavior is the underlying concept of how living organisms act when presented a certain situation or environment. Understanding animal behavior in simple organisms such as termites can give us basic insight into how animal behavior works. In our experiment we tested termite “handedness” – if termites prefer to turn left or right. We did this by placing a termite in an ink path with a fork in it which would cause the termite to choose between going left or right

Ink Chromatography Lab Background Information Paper chromatography is an analytical method that is used for separating and identifying mixtures of substances into their smaller parts. Paper chromatography works because the ink used contains several dyes (pigments) that when place on porous paper are dissolved in a solvent by capillary action. When the pigments (solutes) are dissolved in the solvent (water & alcohol mixture) they move through the paper at different rates depending on their
