Study the above figure. Explain how you would develop concept based on the information in Figure 11 Your answer should be based on the following steps: •Identify two common characteristics P1 – Shiny and lustrous P2 - Good conductor of electricity / heat P3 – High boiling / melting point P4 – Strong P5 – can be beaten and pulled •Develop initial concept Any two points above are metal Eg : Good conductor of electricity and strong are metal* •Give other example and non-example in relation to the concept Other example : lead // zinc // gold Non-example : sulphur // chlorine // bromine // iodine •Explain the actual concept Metal are substance that any two points Eg : *Metal are substance that are good conductor of electricity and strong
