Module 2: How the Idea of Atoms along with the Idea of Elements Evolved

                   The second module talks about the progression of the concept of atoms and elements from the ancient times (500 B.C.E) to the sudden rise in intellectuals in the golden age (1600's to 1800's). This series of discoveries eventually leads to the branching out of the fields Nuclear Chemistry and Nuclear Physics, the applications of which in the present day proving to be boundless.
                   
                   Like the previous module, this one contains three lessons, their key questions indicated below as guide:

Lesson 4: The Nuclear Model of an Atom
                   Merely a review lesson, the aim is to align students' contrasting concepts (if any) about atoms and correct some misconceptions. Here, the basic chemical concepts involved in chemical reactions are recalled upon discussion (e.g. atomic number, atomic weight, valence electrons, etc.). Key Questions are as follows:
a. What are atoms?
b. What are the different subatomic parts? What are their role/function especially in chemical or nuclear processes?

Lesson 5: The Development and Discovery of the Atom and its Subatomic Parts
                    Having aligned our concepts and corrected misconceptions about atoms, the group shall now find it easier to relate to the discussion about how man's knowledge on atoms evolved from a mere idea to figuring out its exact structure and nature. Key Questions are as follows:
a. When did the IDEA of atoms first come out? Who introduced it?
b. Were there contrasting beliefs about atoms and elements in the past? Whose?
c. Who discovered the different subatomic particles? How were they discovered?

Lesson 6: From Alchemy to Chemistry
                    Understanding the structure of the atom eventually led to discovering its vast range of applications. Key Questions are as follows:
a. How did Alchemy springboard the branch of science called Chemistry?
b. How are they similar?
c. How did Dalton's Atomic Theory help understand the concepts behind chemical elements?
