Answer this question: A teacher is doing an experiment in class to show the importance of physical properties to classify matter. He has six samples of different materials of the same mass of 12 grams (g). Some samples are bigger than others, but they all have the same mass. The teacher classified the samples into two groups using just one physical property. Then he asked the students: “Which physical property did I most likely use to sort the samples into these two groups? Group 1
Sample of aluminum Sample of steel Sample of copper
Group 2
Sample of glass Sample of plastic Sample of wood
Here is the list of different properties that you studied in this document: Solubility, density, thermal or electrical conductivity, magnetic property, and melting and boiling points. Write on the line which property you think the teacher used to classify the different materials: .
