| 7 | properties of metals, definition of metals physical properties of metal. mechanical properties chemical properties | Teacher: Tell the students that, the physical properties of metals are the characteristic of metals that can be obscene and measure. they are not acted upon by external force. e.g. color and density. Melting point electrical conductivity. Characteristic of metals which in being acted upon. it determines the range of usefulness of the metals. e. g. fusibility. this is conformed with the chemical composition and chemical reaction of metals e. g. matting, tempera ion and corrosion resistance |
| 8 | Physical properties of metals, ductility malleability hardness | Teacher: Pick a mild steel plate and use lack saw bleed to cut the metal to demonstrate the ability of metal to withstand, scratches, moers, abrasion or in dentition by harder bodies. Malleable metals should be homered, rolling. |
| 9 | Production of metals, production of metals type of metals. and their sources. steel, pig iron, iron ore, copper, cast iron, aluminum etc. method of extraction :- furans used for the production of metals – blast furnace. | Teacher: show different types of metals to students and state their sources. -state methods of extracting of ore from the earth crust. explains the uses of the metals listed. |
| 10 | production of metals, Bessemer counter process -open heart furnace -reuerboratony formulae etc. | Teacher: Sketch different furnaces for students to seed explain the principle of operation for reach of the metal production e.g. steel and pig iron etc. mention the three basic meridian used for the manufacturing processes |
| 11 | form of metals, sheet, flat, plates, square, chorines section, round pipes u shape, angle shape etc. | Teacher: Introduce students to different form of metals presenting different forms of metals to them and state how those metals are melted before running the melts into different sizes and shape of mold. which can then be used for constructional purposes |
