This lesson contains three parts and probably will take a double lesson.
The first, introductory presentation looks at where three different, common metals come from and introduces the ores of Zinc, Magnesium and Iron with a visual comparison with the pure, elemental metal. There is a slide showing a vast open-cast Haematite mine to show the scale of ore extraction to supply our demand for metals.
The second presentation is for the basic metal and dilute Hydrochloric acid practical.
It shows the basic method, safety and comes complete with a blank results table to project onto the whiteboard.
It also contains a Teacher Demonstration of how to collect the resultant Hydrogen gas - in order to demonstrate the characteristic 'squeaky pop' of ignited hydrogen.
Finally, there is a worksheet for more academic groups to learn how to name the salts produced from the reactions of the different metals with hydrochloric acid reactions.
If you like this lesson, please don't forget to review it and feel free to browse my shop where there are many more.
Many thanks
