1. Marvellous Metals By Elizabeth Ratcliffe

2. Properties of Metals Metals are useful – most are good conductors of electricity and heat. Most are shiny when they are cut. Some are magnetic such as steel. Every metal, except mercury, is not a liquid at room temperature. The core of the Earth is solid iron and nickel according to scientists.

3. Reactive Metals You can test reactive metals with a flame test. Different metals have a different flames. Potassium burns lilac and copper burns blue-green. They can be used for fireworks.

4. Reactive Metals The reactivity series shows how reactive metals are. The least reactive metals are pure like platinum.

5. Groups of Metals – Noble Metals The unreactive metals, such as gold and platinum, are noble metals. They are pure metals. They are good for making coins, masks and jewellery as they don’t tarnish so they look as good as new for years. http://theancientweb.com/wp- content/uploads/2015/01/Greece_Ag amemnon_Mask.jpg

6. Groups of Metals – Alkali Metals The alkali metals are 6 metals that are very reactive, like potassium and sodium. They have low melting points, they are also very soft and easy to cut. They all react with water. Potassium explodes when it touches water and burns in oxygen!

7. Groups of Metals – Alkaline Earth Metals These are not as reactive as the alkali metals but they are more reactive than the noble metals. They are harder than alkali metals. Some form the veins in limestone. Calcium Carbonate

8. Groups of Metals – Transition Metals These metals have lots of uses because they are easily shaped and are strong. Metals include iron, gold and copper. Transition metals can be used for bike frames. http://www.whycycle.co.uk/cms- files/0timetrials.jpg

9. Groups of Metals – Poor Metals There are 9 poor metals. They are generally pretty soft. They are rarely used on their own. One of the poor metals is Polonium, it is deadly and highly radioactive. It was discovered by Marie Curie and it was named after the Latin for Poland which is Marie’s homeland. Another poor metal is Aluminium which is used for bikes, cars, spacecraft and cooking foil.

10. We have found out… Metals have different properties Some are hard and some are soft Some are poisonous or radioactive and some are not Some have different melting temperatures They can be used for many different things Scientists are still finding out about different metals, and uses for them today.
