Science 9 Name: ______________________ Date: ________________ Class: ____________ Properties of Metals and Non-metals Lab Objective: To distinguish between metals and non-metals Background: Most elements can be grouped into two different categories – metals and non-metals. The properties (characteristics) of metals are very different than those of non-metals. Materials: Carbon (charcoal) Aluminum foil Copper wire Sulphur Extension (optional) Small light bulb 2 Alligator clips D battery Steps: 1. Obtain all materials from your teacher. 2. Make observations about each element. 3. Complete the table below. Extension 4. Set up the alligator clips, battery, and light bulb according to the diagram below. 5. Attach the other end of the alligator clips to the material being tested. 6. Record your observations on conductivity. Sample of aluminium, Science 9 Element Name: ______________________ Date: ________________ Class: ____________ State of Matter (solid/liquid/gas) Malleability/Ductility (can it be bent or stretched?) Lustre (shiny or dull) Conductivity (does it conduct electricity?) Aluminum Carbon Copper Sulphur 1. Which of the elements are metals? _________________________________ 2. Which of the elements are non-metals?______________________________ [HINT: Use your coloured periodic table] Science 9 Name: ______________________ Date: ________________ Class: ____________ Analysis Based on your observations and what you know about these elements, fill in the table below that summarizes the properties of metals and non-metals. Metals Non-Metals State at room temperature (solid, liquid, or gas) Lustre (dull or shiny?) Malleability and ductility (bendable or brittle?) Conductivity (ability to conduct heat or electricity) 1. What do you notice about the properties of metals and non-metals? ______________________________________________________________ ______________________________________________________________ Extension 2. Based on its location on the periodic table, what properties would you expect sodium (Na) to have? ______________________________________________________________ ______________________________________________________________ ______________________________________________________________
