  1. Use this powerpoint to guide you through today’s lesson an use it to help you with homework Year 7 Particles Topic

  2. BATs Suggest what evidence we have today to suggest that matter is made up of particles L4 Describe how thinking has changed over the years L5 Research information from a range of sources L6 Activity Use the internet to find the year in which major discoveries about atoms were made. Add these to the timeline. Put the scientists in Chronological order (oldest discovery first) The History of Particles

  3. The History of Particles • Democritus (460-370BC) If you cut something up finally you will have an indivisible particle ‘atomos’ separated by empty space ‘vacuum’ • Aristotle (350BC) Thought that you couldn’t have a vacuum • Newton (1643-1727) Particles of a gas are held together by aether • Boyle (1627-1691) Thought that Aristotle was right.. vacuums do exist! • Torricelli (1643) Created a vacuum • Einstein (1879-1955) Proved that aether definitely doesn’t exist

  4. How much can you remember about Particles? • http://www.bbc.co.uk/schools/ks3bitesize/science/chemistry/particle_model_intro.shtml • http://www.docbrown.info/ks3chemistry/7Gmc.htm • Try these quizzes about particles – all correct gets a merit!

  5. Plenary and Homework • Create a crossword or wordsearch or quiz about the Particles topic • You need to make up questions about particles. • The answers to these questions will be the words in your crossword or wordsearch. • Finish this at home – you will try it out on a partner next lesson!!
