THE HISTORY OF THE ATOM – PART ONE!
ANSWER THE FOLLOWING QUESTIONS, WHILE WATCHING THE PRESENTATION ON THE
ATOM!
1. Who was the first person to come up with the idea that all matter, like you, me, trees, desks –
are made of invisible particles called atoms? ____________________
2. Who destroyed the idea that we were all made of atoms? ____________________
3. During the middle ages, science was lost to most of the world. Who was actually doing
science, and had great technology, in the middle ages? ____________________
4. Who was keeping scientific ideas and experiments from being done during the middle ages?
____________________
5. Who was the first person to prepare laughing gas, and invent soda pop?
____________________
6. Who actually discovered oxygen, but didn’t realize it at first? ____________________
7. Who proved the theory of phlogiston wrong? ____________________
8. Who proved that substances actually burned oxygen, and did not give off phlogiston, by
weighing materials before and after they burned? ____________________
9. What Law did Lavoisier prove, that states that matter couldn’t be created or destroyed?
____________________
10. Who came up with the Law of Definite Composition, which says that all substances are made
up of definite amounts of each element? ____________________
11. Who stated that elements always come together in multiple ratios – like carbon and oxygen
can make C1O1, or CO2? ____________________
12. Because elements come together in ratios, that means that they are made of atoms. What
schoolteacher came up with the Atomic Theory of Matter? ____________________
13. The Atomic Theory of Matter states that atoms of different elements are going to look…..

scattered about, like chocolate chips in a chocolate chip cookie? ____________________
32. The plum pudding model freaked people out, because they did not believe they were made of
