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