Include a diagram if you like) Insert various Comet’s Pictures Here The Portsmouth Grammar School Physics Chemical Composition (What are comets made of? Special Challenge: Why do we see comets’ tails, and why do they appear to trail off at an angle behind the comet?) Where do Comets come from? (research SHORT-PERIOD comets not long period ones – the long-period ones come from the Oort cloud which is way over the top for Year 9! Simply and BRIEFLY discuss the orgins and discovery of SHORT- PERIOD comets.
