What is a good topic to base my science poster on?

Its something about breakthroughs in science and I have to make a poster board presentaion with pictures and everything like that. My sister did the polio vaccine.

1. Confocal microscopy! You can download lots of great pictures. Acutally you could do "microscopy" generally and explain traditional light microscopes, electron microscopes, and confocal light microscopes. Developments in this field have revolutionised science by allowing scientists to study structures inside cells. Or if you need something more famous you could do the discovery of DNA and then link it up to the sequencing of the human genome.
2. there can be several things, a useful website is how stuff works? u want to make it interesting and something attractive that relates to everyone. i have done many and from my experience often the best is not because of the content but because of the presentation of the poster and explanation of it, ie imagine you are the best teacher explaining this amazing concept. remember its does not have to only be on medicine it can also be on chemistry, or phys .... hope that helps ;-)
3. penicillin The story of Sir Alexander Fleming's discovery of penicillin is well known. In 1929 he discovered a mould growing on a glass dish in his laboratory which appeared to kill the bacteria he was cultivating. In his follow-up studies, the crude penicillin broth that he had extracted from the mould was non-toxic to rabbits and mice.1 But it rapidly disappeared from their blood, and it seemed to work very slowly in the test tube. These results led Fleming to believe that penicillin would only be useful as an antiseptic for surface infections rather than as a powerful antibiotic for general infections. After this, he rather lost interest in his discovery, although a few patients with eye infections were successfully treated by the application of impure extracts of penicillin broth in the 1930s. Mouse protection test proves that penicillin fights bacterial infections There was great interest in developing antibiotics at the start of the 1940s because of the enormous death toll from septic infections. One of the substances tested by researchers was Fleming's crude penicillin broth. Had Fleming himself carried out a simple and well- established animal test2, the mouse protection test, then the potential of his discovery might have been realised ten years earlier. Howard Florey and Ernst Chain, searching for potential antibiotics at Oxford University in 1940, used the mouse protection test. This animal test was first described in 1911, was in routine use from 1927 and ultimately led to the introduction of sulphonamide drugs in the 1930s. In the test, Florey and Chain injected eight mice with a lethal suspension of bacteria, and four of these were also given penicillin. The fact that the four mice which received penicillin lived and all the rest died was definite proof that penicillin worked against serious bacterial infections. It was this test which set Florey, Chain, Heatley and others on the long road to purifying and mass producing penicillin. In 1945, Alexander Fleming, Ernst Chain and Howard Florey received the Nobel Prize for the discovery and development of penicillin.
