1. 4.5 Fire and brimstone 18 February 2016 Are the following materials metals or non metals? Osmium Hydrogen Chromium Argon Uranium Radon Plastic Salt

2. Learning outcomes I can: Before the unit I have learned this I have revised this I can identify elements and compounds from their names. (Level 5) I can explain the difference between elements and compounds using ideas about atoms. (Level 6) I can talk about how the Periodic Table is arranged in groups and periods. (Level 3) I can tell if an element is a metal or non-metal by looking at the Periodic Table. (Level 4) I know some properties and uses of metals and non-metals. (Level 4) I can identify whether an element is a metal or a non-metal from its properties. (Level 5) I can use the Periodic table to make predictions about the properties of elements. (Level 7) I can use information about chemicals to write down a detailed risk assessment. (Level 6) I can use my observations to explain when a chemical reaction has happened. (Level 6) I can summarise chemical reactions using word equations. (Level 6) I can describe how distillation separates mixtures. (Level 5) I can explain how a mixture is different to a compound or element. (Level 5) I can talk about why the total mass does not change during an experiment. (Level 6) I can discuss how chemicals can be used for both peaceful uses and in war. (Level 5) I can use symbol equations to show what happens during reactions (Level 7)

5. Learn about: What non-metals are like, and what they are used for The differences between metals and non- metals New materials for special used

6. Sulfur You find sulfur where you find volcanoes Sulfur is a non-metal Long ago, it used to be called brimstone Not many elements are non-metals Most non-metals are gases, one is a liquid and the rest are solids The properties of non-metals are generally the opposite of metals

13. To conduct or not conduct Energy ball demo

14. Uses of non-metals Although there are fewer non-metals than metals, they have a lot of important uses

16. Metals or non-metal?

17. Jasmine, Becca and Ryan have different ideas about how to decide which of these elements are non-metals and which are metals Jasmine suggests putting all the solids in one group as all metals are solid, the others are then non-metals Ryan thinks we should put all the conductors in one group as metals conduct heat well. All the others will be non-metals Becca disagrees and thinks that those that conduct electricity are metals so the others are non-metals

18. Question For Jasmine, Becca and Ryan, make a list of which elements they have decided are metals and which are non-metals Explain who has the best idea (6)

20. New materials from non-metals Scientists are able to make new materials from non-metals Carbon fibres are made from carbon Carbon is a weak, brittle substance but carbon fibres are very strong anf light The body of the Eurofighter is strengthened with a large proportion of carbon fibres As well as making the aeroplane strong and light, the carbon fibres make its body hard for radar to detect

21. ‘All metals are similar, but non- metals are all different to each other’
