Lesson Starter IN YOUR OWN WORDS, write down the meaning of the word displacement and give and example of a displacement reaction.

Learning Intention To learn what an ore is To extract a metal using heat and carbon

Discovering metals Unreactive metals discovered first Unreactive- uncombined- pure Nuggets

Discovering metals More reactive metals combined with other elements Ores

Extracting metal Different ways More reactive the metal- more energy needed to separate it Not very reactive- heat alone Metals like zinc and iron extracted by heating in presence of carbon

Experiment AIM To extract copper from copper oxide

Apparatus 1 test tube Copper oxide Charcoal (carbon) Large beaker of cold water Bunsen burner Filter funnel Metal tongs

Method Place 1 spatula of copper oxide and 1 spatula of charcoal in the test tube Mix thoroughly Heat with blue flame After 5 mins plunge test tube into beaker of water that is inside a sink- CAREFUL Filter the solid out of the beaker of water and sift through the solid to look for signs of copper Write a short report including an AIM, diagram of the experiment and a description of what happened

Lesson Starter What metals would you find un-combined in the earth? What is a metal ore? Briefly describe how copper was extracted from copper oxide

Extracting metals More reactive metals= much stronger bonds More energy needed Most reactive metals- electricity Electroylsis

Experiment Collect electrolysis kit and copper chloride solution Connect equipment- get it checked before switching on the power Record any observations about what is happening at each electrode Draw a diagram in the space provided

Revision- acids, alkali, metal
