<br/><br/> A scientist investigating the Everglades observes many things. You use your senses too to find out about other objects, events, or living things. Scientists might estimate the size of a tree in the Everglades. When they estimate, they tell what they think an object´s size, mass, or temperature will measure. Then they measure these factors in units.
