=Dmitri Mendeleev= For my Invention Convention project I have to write a one- person speech and present it in character. The inventor I chose Dmitri Mendeleev (Men- de- le- ev). He was a Russian chemist who invented the all important periodic table of elements. I chose this person because I myself am Russian and I think he sounds like a very interesting man.

1. Q: Who is the inventor? Dmitri Mendeleev was born on February 8th, 1834 in Verhnie Aremzyani village, near Tobolsk (Siberia). His parents were Ivan Pavlovich Mendeleev and Maria Dmitrievna Mendeleeva and he was the youngest child of his 17 siblings.His dad died soon after his mom's glass factory had burned down. His mom wanted him to have a good education so he attended school at age 13, 10 weeks before is mom's death. He later studied in France under Henri Regnault and in Heidelberg, Germany, with Robert Bunsen and Gustav Kirchhoff. In 1869 he created the first valid periodic table of elements.In 1870 he married. He died January 20, 1907 (age 72) of influenza in St. Petersburg, Russia. 2. Q: What about their life impacted their ability to create the invention? Mendeleev didn't have such a smooth life time but he was very successful otherwise. He was able to learn science from one of his sister's husband. I'm not quite sure what inspired him but he went all over Europe to study and I think he wanted to be a chemist from the start. It never said why he wanted to be a chemist.

3. What is the invention? Dmitri Mendeleev was the first man to create a valid periodic table of elements. The periodic table of elements is a chart that explains the chemicals in our everyday products. For example, H20 as we all probably know is water because water is made up of hydrogen squared and oxygen. Element 101 was named mendelevium in his honor. To the left is the original copy of the chart.

4. How did it come to be invented? The reason he came up with this idea is probably because he was an expert on atomic weights. After he became a teacher, he had written a textbook on the principles of chemistry.He attempted to classify the elements according to their chemical properties and eventually he tryed different patterns which led him to the periodic table of elements. After he invented it he realized a mistake. He suggested that atomic weights of gold and tellurium were incorrect. He also realized three elements were missing. Unfortunatly, before he could discover them others did. He was one of the greatest scientists of his time.

5. How did the invention affect society at that time? The periodic table of elements did not immediately become popular. It was valued more in late 1800's. Not many people back then payed attention to the chemical elements in their food or beverages.

6. When did it completely become popular? The periodic table of elements never became extremely popular but it had some attention.When it was first invented no one really payed attention. It really became popular in the late 1800's.

7. Is the invention still used today? Yes, the invention is used by many chemists today. In addition, some people have large posters of the periodic table of elements in their homes. Why is it still used today? It is still used today because chemists and other scientists need and want to study the things around them and the periodic table of elements is the perfect helper. How is it still used today? The periodic table of elements is used by chemists to study the things around them. Are there any modifacations? Yes, later on three other missing elements were discovered. The three—eka-aluminum (gallium), eka-boron (scandium), and eka-silicon (germanium)—were discovered by Paul-Emile Lecoq de Boisbaudran, Per Cleve, and Clemens Winkler in 1875, 1879, and 1886.

8. Could this invention have an impact on the future? Explain. Yes, this invention could definitely be used in the future. Many chemists will probably use it and maybe more chemical elements will be discovered. More and more people will decide to put a poster up in their house of the periodic table of elements because some chemical elements may be good for your body. Maybe some day they will make a scanner that will be able to scan the object and say what chemical element it contains. You never know...

= My Speech = Privet! My name is Dmitri Ivanich Mendeleev and I invented the periodic table of elements. I was born on February 8th, 1834 in a small village, near Tobolsk Siberia as a Russian boy. Ivan Mendeleev and Maria Mendeleeva are who I would call ma and pa. It was never easy being the youngest of 17 siblings. My dad died soon after my mom’s glass factory burned down. My mom wanted her youngest child to have a good education so I went to school at age 13, 10 weeks before my mom died. I later studied in France and in Heidelberg, Germany. I studied atomic weights and then wrote a textbook called “The Principles of Chemistry”. In 1869, I invented the first valid periodic table of elements. A year later, I got married. The periodic table of elements is used by many chemists around the world. Basically what it is is a chart of all the chemical elements that surround us. For example, H2o as we all know it water or hydrogen squared and oxygen. And Hydrogen chemical, number 1, which is the most abundant chemical in outer space. Now it is being used to fuel green cars. In addition, carbon dioxide or Co2 is very abundant in the air around the world. (Points to chart) Here is my all mighty invention the periodic table of elements. It contains an assortment of elements with my favorite Element 101 Mendelevium. This one here is more modern than my original copy here. (points to original chart) I made this is invention when I was trying to classify the elements according to their chemical properties and eventually I tried different patterns which led me to the periodic table of elements I could just go back and remember when one night as I was sleeping I had the idea. I could see all the chemical elements patterns. And the next day I went to work. Life was very hard for me because both my parents were dead but I made it there anyways. It didn’t immediately become popular when I created it but in the late 1800’s it started to be more valued. Hopefully, in the future the top notch scientists of Russia or anywhere in the world will create a machine able to classify the chemical elements in what ever it is scanning. But for now we can just stick with the paper. Apparently, I heard that I did not include 3 always important chemical elements which were then discovered by other scientists. Sadly, I died on January 20, 1907 at age 72 of influenza in St. Petersburg, Russia. I was glad to hear that element 101 is named Mendelevium in my honor. I had won many awards but never the Nobel prize. I was known as one the greatest scientists of my time. To some people my invention was world changing and important but to others it is just another invention. But some people just don’t the importance of the chemical elements and how much they surround us in our everyday lives. I hope more people could understand this chart and realize that chemicals are all around us. Many hih school students take a chemistry class where everyday they look at the periodic table of elements and think “How in the world did someone invent this. Maybe you someday in high school you will take chemistry class and then you might just think of me.

=Thomas Edison= My questions for answering. Source: [|About.com] 1) When was Edison born? A: Edison was on February 11, 1847 in Milan, Ohio

2) Describe what Edison’s education was like. How does Edison’s education compare to your education? A: Edison didn't really have the best education out there. His mom taught him reading, writing, and math and everything else he would learn was in books that he read. Edison was only able to attend school for a few months. His education is quite different from mine and many other people's. I think the reason he went to school for such a short time was that his family could not afford it but he was still able to have a very successful future.

3) How did Edison spend his free time? A: He spent most of his time reading scientific and technical books and I am guess that is why he has so successful.

4) What opportunities did Edison have as a telegraph operator? A: I think his opportunity as a telegraph opportunity was that he was able to gain experience and travel the country.

5) What was Edison’s first successful invention? A: Thomas Edison's first successful invention was the "Universal Stock Printer". He was paid $40,000 dollars and he built a small laboratory in Newark, New Jersey in 1871. He was able to do a lot of work and make his invention better and better.

6) Edison’s second major invention was the tin foil phonograph. What did it do? The tin foil phonograph was Edison's second major invention. Basically, it was like a tape recorder able to record and play sound.

7) What contributions did Edison make to the electric lighting industry? If Edison had not thought of such a wonderful idea as the light bulb we might not have had any lights or electricity. We would sit in a classroom lit by day light or lanterns.

8) What was Edison’s third invention? How can its impact be seen on the world today? Edison's 3rd invention was motion pictures. Now we watch cartoons almost daily and it certainly makes a big difference today.

9) Describe one challenge that Edison had to face. Thomas Edison must have faced the challenge of loosing money in his investments. It must have also been hard to make the choices because one wrong choice could lead to a lot of money loss.

10) What do you think Edison will be remembered for the most? Why? Thomas Edison will probably be remembered for was his creativity and his skill. It is quite amazing that he did not have the greatest education but he still had a very successful history.

1- How do you think Thomas Edison improved the quality of people’s lives in the 1900’s though technology. He certainly made a big impact in 1900's. Now we can watch cartoons and regular T.V. We can turn on lights instead of lighting a candle. There is certainly a difference that he made in this century.

2- How have Thomas Edison’s inventions improved the quality of your life today? If Edison did not have such a wonderful idea life would look much different today. His inventions CERTAINLY improved life today.
