DOC Physical and Chemical Change Experiments A physical change involves a change in physical properties. Physical properties can be observed without changing the type of matter. Examples of physical properties include: texture, shape, size, color, odor, volume, mass, weight, pH and density. Chemical changes are changes substances undergo when they become new or different substances. Physical Change vs Chemical Change Lab physical changes are: melting, freezing, condensing, breaking, crushing, cutting, dissolving, and bending.

DOC Physical & Chemical Change Lab - The Science Queen Background: When a physical change occurs, only the form of the substance changes. Chemical changes, however, result in the formation of new substances with different properties. Some general signs of a chemical change include a change of color or odor, the formation of a precipitate (solid), the formation of a gas, and a change in heat or light. In this lab, you will perform different activities and, based on your observations, determine whether a chemical or physical change has taken place.
