TEK 3

• C) evaluate the impact of research on scientific thought, society, and the environment;

• (D) describe the connection between chemistry and future careers;

• (E) research and describe the history of chemistry and contributions of scientists.

 

Blood Typingand the Discovery

• In 1865 Augustinian Monk “ Gregor Mendel” found that individual traits are determined by “factors” later know as Genes, which are inherited from parents. His approach transformed from art to science. he started with parents from the know genetic background. He deduced that genes come in pairs and are inherited one from each parent. He discovered the laws of Inheritance:

• The Law of Segregation• The Law of Independent Assortment• The Law of Dominance • He did experiments on Pea plants that lasted for eight yrs. 1856-1863.

After that he published his results in 1865.his works and the laws of Inheritance was not appreciated at that time. During the time he grew over 10,000 Pea plants, keeping tracks of progeny number and type. It wasn’t until 1900 after the rediscovery that his experimental results were understood.

Today in Science Dealing with DNA

• In the world that we live in now you can use DNA in Forensic Evidence can be used now in court offences and to identify some one with hair strands and finger nails. There’s a lot of things now that Scientists can use now to do resources on people. This comes in handy when dealing with DNA study.

• “Skilled examiners of fingerprint evidence agree that the process of comparing latent fingerprints of unknown origin with inked impressions of known origin is an "art," rather than a science?”

• So the study of DNA has helped us today in the history of Scientific work.

Antoine Lavoisier• Antoine L. Lavoisier was a Frenchman who was born into Paris on

August 26, 1743. The son of a very prosperous lawyer, was educated at the College des Quarte Nations were he studied range of academics.

• He was following his father foot steps, he obtained his license to practice law in 1764. He shortly turned around and gave his life to science. He studied Geology under Jean Etienne Guettard from 1763-1767. He wrote and published a paper on How to Improve the Street Lighting in Paris. His work on agriculture, he became a member of the Royal Academy of Science in 1768. He also joined in the Farmer’s General a (company were they collected taxes and tariffs for the Government). Three years later he married a farmer general daughter where Jaques Paulze learning how to read (which Lavoisier did not know how to do). Also becoming a skilled draftsman and engraver.

• In may of 1794 he and the others (Farmer’s General) were arrested and thrown in jail. The trial lasted of about one day and were all ordered to to executed. He tried to ask to finish some scientific work and the judge said “No need for scientists. His body was thrown into a common grave.

What he did?

• He invented the balance of .0005grams.

• He played active parts in the events of French Revolution.

• He served in the committee of the hospitals and the prisons of Paris

• During the revolution he published a report on the state of France’s Finances.

• In 1789 he became a alternate deputy and drew up codes for other deputies to follow.

• He moved to Arsenal in Paris and created a laboratory for his growing experimentations.

How he Impacted Science?

• Today we use the balance for things that deal with science.

• To equal out things that we need to take notes on.

• We now use labs for experiments to get the idea of how things work.
