CKS 3: Yr 8 Chemistry Unit 3 –What's My World Made Of? Part 2 Lesson number: 2. Lesson Title: The Periodic Table- Metals and Non Metals Lesson Outcomes Learning Outcome 1: Task 1: Group elements explaining the characteristics used for doing so. Level 5 Learning Outcome 2: Illustrate trends in elements using periodic table including what elements are metals and non metals. Level 6 Learning Outcome 3: Explain the trends in periodic table using secondary data. Level 7 How I did Targets Connector (Level 4) Write the names of first 10 elements and their symbols from the periodic table. Use your diaries TJ

BIG picture Key Question: What is the difference between an element and a compound? • What skills will you be developing this lesson? • HSW- by planning and carrying out an investigation/ Interpreting data/ evaluating an experiment • How is this lesson relevant to every day life? Chemicals and reactions used to work machines for example, for fireworks • Literacy- by writing explanations using correctly spelt keywords and good grammar. Where does this lesson fit in to the rest of the topic? Lesson 2 • Team work- during a practical investigation • Quick Discussion: • What do you already know? • Participation- during a practical activity • Reflection- through self and peer

Keywords: Create sentences using the keywords to show that you know what they mean. Put your hand up if there is any key word from the list that you don’t understand. Periodic table Group Trend Secondary data

New Information for Learning Outcome 1 • Visual: Demonstration • Audio: Demonstration • Kinaesthetic: Class experiment

New Information for Learning Outcome 1 A standard set of symbols is used to represent elements l The symbol for many of the more common elements uses just the first letter of the name. H = hydrogen C = carbon F = fluorine l Others elements have the first two letters. Li = lithium Al = aluminium He = helium O = oxygen N = nitrogen I = iodine l Some of the symbols are not always as you might expect. Pb = lead Au = gold Ag = silver

New Information for Learning Outcome 1 Two important rules should be followed when writing the symbols of elements so that there is no confusion. 1. The first letter of an element’s symbol is always a capital letter. e. g. N (not n) for nitrogen 2. If there are two letters in the element’s symbol, the second letter is always a small letter. e. g. Co (not CO) for cobalt No, Watson! It was carbon monoxide poisoning – not cobalt.
