Transcript of Louis Pasteur

The first thing that we are going to talk about is his discoveries. Louis Pasteur's most famous discovery was when he found out bacteria made milk sour. Pasteur was appointed to make this test by the king and succeeded. He was excited because this was his first discovery which inspired him to invent a way of cleaning milk; pasteurization. As you may have already known, pasteurization was named after Louis Pasteur. Another famous discovery was when he developed 7 vaccines against diseases.
Louis Pasteur was born on the 27th of December 1822 in Dole, France, into a poor Catholic family. He was the third child of Jean-Joseph Pasteur and Jeanne-Etiennette Roqui. In 1827 the family moved to Arbois, where Pasteur attended primary school in 1831. He was an average student in his early years, and not particularly academic, as his interests were fishing and sketching. He made portraits of his parents and friends when he was 15 which were later kept in the Pasteur Institute in Paris. In 1839 he entered the French college and earned his BA degree in 1840. He continued there for a BSc degree with special mathematics but failed. He succeeded in 1842 from Dijon (an eastern city in France) with a poor grade in chemistry. After failing the entrance test for another college (The École Normale Supérieure) in Paris in 1842 and later on he succeeded in 1844, and received his medical licence the next year. In 1846, he was appointed professor of physics at a college (Collège de Tournon at Ardèche) but Professor Antoine Jérome Balard wanted him back at the other French college (École Normale Supérieure) as a graduate assistant for chemistry courses. He joined Balard and simultaneously started his research in crystallography.
Bacteria may be an unpleasant thing that can cause a lot of diseases and sicknesses. But we all know that it plays an important role in our life so that is why today our group chose the topic of 'Breeding Bacteria' for our experiment.

What you'll need:
1) Petrie dish
2) Agar (Jelly)
3) Cotton buds
4) Old newspaper (to wrap petrie dish when disposing)

1) Prepare your petrie dish of agar.
2) Using your cotton bud, swab a certain area of your classroom (E.g. collect a sample by rubbing the cotton bud on a surface of your choice).
3) Rub the swab over the agar with a few gentle strokes before putting newspaper on and sealing the petrie dish.
4) Allow the dish to sit in a warm area for 3 days.
5) Check the growth of the bacteria each day by making an observational drawing and describing the changes.
6) Dispose of the bacteria by wrapping up the petrie dish in old newspaper and placing in the rubbish
Thanks to Louis Pasteur, now we all know why milk becomes sour. As we now know how to pasteurize, we can now purify milk so we can actually drink it. Without his discovery, many of us would be dying from an unknown disease caused by the bacteria in milk. Many people appreciate his discovery and respect him. Our group found Louis Pasteur as a really intriguing topic to learn about. We hope you have learnt more about Louis Pasteur from our presentation. We also hope that you will enjoy our experiment on 'Breeding Bacteria.'
