Observing Properties

The video tutorial introduces the concept of properties, which are characteristics determined through observation. It covers various properties such as color, hardness, reflectivity, thermal and electrical conductivity, and magnetism. The tutorial guides students on how to set up a data table to record observations of different materials. It provides a step-by-step demonstration using a wire to observe and record its properties, including color, hardness, reflectivity, thermal and electrical conductivity, and magnetism. Students are then instructed to observe and record properties of additional materials and attempt to identify them.
