Teachers, save “(A2) Classifying by Properties” to assign it to your class.

An observation is something you find out about objects, events, or living things using your senses. A property is a characteristic of something that you an observe. Color, shape, texture, size, and composition are properties. Composition means what it is made of. Objects and substances can be classified, or sorted into groups, based on shared properties. Classifying is the process of using observations to group objects or events according to similarities and differences. There is always more than one way to classify objects because all objects have more than one property. Hands-on Activity 1. Observe the objects on the tray. 2.
