Learning Intention To be able to state the meaning of the word ore To be able to explain how to extract metal from ores

Elements can be split into two groups: METALS and NON METALS

Metal Ores Naturally occurring compounds Rocks or Minerals containing metals Found in earth’s crust

Metal Ores (copy) Metal elements (such as iron and aluminium) are found combined with rocks and minerals in the EARTHS CRUST. These naturally occurring COMPOUNDS are called ORES. Compounds are 2 or more elements joined together. The element looks very different from the metal ore it is extracted from.

Extracting metals from Ores Mining Physically remove metal ores from ground Metal ore looks different from the pure metal element Bauxite – aluminium oxide (Al2O3) Haematite – iron oxide (Fe2O3) Malachite – copper carbonate (CuCO3)

Lesson Starter (copy and complete) Metal Ores Metal ores are physically removed from the ground through the process of __________. The pure metal often looks very _________ from the metal ore.

To safely extract metal elements from compounds Learning Intention To safely extract metal elements from compounds

Extracting Metal from Ores Copper Oxide Tin oxide Aluminium oxide Heat with Carbon

Extracting Metal Elements Write a list of all the equipment and chemicals you used for these experiments Write a list of detailed instructions on how to carry out the experiment Write a detailed explanation of how to ensure safety with the experiment Draw a labelled diagram of how to set the experiment up

Lesson Starter What is an element? Where would we find metal ores? What are metal ores? How do we get the metal element from an ore?

To learn about the different PROPERTIES of elements Learning Intention To learn about the different PROPERTIES of elements

The elements Over 100 elements 84 metals 21 non metals Each element is different- different properties

Task Compare metals and non metals: Is it shiny? What state of matter? Feel them- brittle or hard? Do they conduct electricity? Do they conduct heat?

Properties of elements (copy) Metals are ______ when polished, they are good conductors of _____ and _______. Non- metals are _______ conductors of head and electricity.

States of Matter All metals solid at room temp except MERCURY Non-metals= solid, liquid or gas Solid non-metals= brittle MERCURY and BROMINE are the only LIQUIDS

Elements: States of Matter (copy) All metals (except mercury) are solid at room temperature Non-metals can be solid, liquid or gas; solid non-metals tend to be brittle. The only liquids at room temperature are MERCURY and BROMINE.

A list of all the elements https://www.youtube.com/watch?v=zGM-wSKFBpo PERIODIC TABLE

Lesson Starter Give 2 properties of a metal Give 2 properties of a non metal Give 1 example of an element which is Solid at room temperature Liquid at room temperature Gas at room temperature Find the chemical symbol for: Carbon Nitrogen Phosphorous berrylium

To learn about the ALKALI METALS Learning Intention To learn about the ALKALI METALS

The Periodic Table Mendelev Split into groups and periods https://www.twig- world.com/film/introduction-to-the- periodic-table-1395/ Mendelev Split into groups and periods Elements grouped based on chemical properties Elements in same group behave similarly

The Periodic Table Group 0: Noble Gases Group 1: Alkali Metals Halogens

The Alkali Metals *watch demos* What do they look like? What do they feel like? How do they react? - Why are they stored in oil? https://www.youtube.com/watch?v=ktIAjIWtEXM

https://www.twig- world.com/film/the-halogens-1420/ Group 7 elements Highly reactive Non-metals

Unreactive Non-metals Gases The Noble Gases https://www.twig-world.com/film/the-noble-gases-1421/ Unreactive Non-metals Gases

The Periodic Table (copy) The periodic table is a list of all the known elements; it was produced by the Russian scientist Dmitri Mendeleev. Elements in the same group behave similarly to each other: The group 1 ALKALI METALS are highly reactive metals The group 7 HALOGENS are highly reactive non-metals The group 0 NOBLE GASES are unreactive gases

Find out as much information about your chosen element as you can. Homework Find out as much information about your chosen element as you can. What does it look like? Is it hard or brittle? Can it conduct heat? Can it conduct electricity? Is it reactive?

Lesson Starter What is an element? Give an example of an element which is a) solid at room temp b) liquid at room temp c) gas at room temp 3. Find the chemical symbol for Nitrogen

Learning Intention To be able to state the difference between an element and a compound

Elements Elements are the building blocks used to make up every substance in the world and cannot be broken down into anything simpler Each element is made of the same type of atom

Compounds A compound is made when atoms of different elements join together

Elements and Compounds (Copy) An element is only made up of one type of atom. A compound is made when two or more elements join together chemically A new product is formed when a compound is made

Elements and Compounds (Copy) Element Compound

Elements and Compounds (Copy) Before the test tube is heated the iron can easily be separated from the sulfur using a magnet. This is because the iron and sulfur are two separate ELEMENTS When the test tube is heated the iron cannot be separated from the sulfur using a magnet. This is because a COMPOUND has been formed

Before You Go Magnesium Oxide Element or Compound?

Before You Go Oxygen Element or Compound?

Before You Go Iron Sulphide Element or Compound?

Before You Go Iodine Element or Compound?

Lesson Starter Draw a particle diagram of a) an element b) a compound Describe the difference between an element and a compound In yesterday’s experiment the sulfur and iron mixture could not be separated with a magnet after it was burned; why?

Learning Intention To give examples of signs of chemical reactions To safely carry out the burning Magnesium experiment

Elements and Compounds Iron + Sulphur  Iron Sulphide New substance made “Marriage” Compound formed- change of name If ends in “ite” or “ate”- oxygen also present “ide” ending if no oxygen Copper + Sulphur + Oxygen  Copper Sulphate

Task: complete the following Sodium + Chlorine  Copper + Sulphur  ______ + _______  Magnesium Hydride Copper + Carbon + Oxygen   Potassium Carbonate

Chemical Reactions 2 or more elements REACT to form a compound ALWAYS a new substance in chemical reaction Signs of chemical reaction

Experiment Apparatus Instructions Goggles Bunsen Burner Heat proof mat Magnesium Ribbon Tongs Collect all your apparatus and set up at your work station Goggles on! Light your Bunsen burner Take a small piece of magnesium ribbon and hold it in the tongs over the flame of the Bunsen burner Watch and see what happens Has a chemical reaction taken place? How do you know? Look at your ribbon now- what is different? Discuss

Making Compounds (copy) When two or more elements react together to form a compound a chemical reaction occurs. During every chemical reaction A NEW SUBSTANCE is made. When Magnesium ribbon was burned in the Bunsen burner, a white powder had formed. Magnesium + Oxygen  Magnesium Oxide

Write a sentence What other sign was there that a chemical reaction took place when magnesium was burned in oxygen?
