Atomic+Theorist+WebQuest

Introduction The foundation of modern chemistry came from the insights and discoveries of a number of scientists who studied and questioned what makes an atom up, its parts and components; and why and what those components are. It is thanks to a large number of people that we know what we know today, and without each of their contributions it is unknown if we would have the knowledge that we currently have or if we would just be figuring it out currently. Democritus believed that everything was made of atoms and Aristotle had a unique, incorrect view of matter and what it was, but slowly those views were either built upon or diminished and the current views of the atomic theory were shaped. Objectives 1. To research the key scientists (theorists) who helped shape the modern atomic theory.

2. To explain the role each scientist (theorist) had in the creation of the modern atomic theory.

3. To compare the relationship between the discoveries made by each of the scientists.

4. To analyze the foundation of the theory and how discoveries made lead to future discoveries by others. Task You are to conduct research about the foundation of modern chemistry by completing this WebQuest. Using the worksheet (Theorists) under the resources section, you will search the given Internet sites to answer the questions on the worksheet. Upon completing the worksheet that contains the information about the theorists, you will use the other worksheet (Relationship of Discoveries) under the resources section to compare and analyze the discoveries and the foundation of modern chemistry.

Evaluation You will complete two worksheets, one on the theorists and one on the relationship between certain factors. Both will be checked by your teacher for completeness and accuracy. You will receive a short quiz in a few days to check your knowledge on the theorists that have contributed to the current atomic theory. The quiz will focus on the exact discovery that each scientist made. Study hard and good luck!
