For my students: this is a story of the beginning of the development of the atomic theory. Now, you are to first listen to the presentation. Your task will then to pick one of the four choices to complete:
1. Create a storybook complete with pictures that would compliment the presentation.
2. Create a diorama to tell a similar story
3. Make models of each stage of development.
4. Create a story for part 2 of the development of the atomic theory that will be coming up.

• The following is an adaptation of a science history story as told by Gregory L. Curran from the Fordham Preparatory school and myself.
•   To borrow an example from Albert Einstein, imagine if you had never seen a clock or a watch before, and someone gave you an intricate Swiss timepiece.  Imagine studying the motion of the hands, but never being allowed to remove the watch face and see the mechanisms which produced the sychronized movements.  If you thought about it long enough, you might be able to come up with a model to explain the motion of the hands, but you could never be sure that your model was an accurate depiction of what was going behind the face of the watch.   In fact, if someone was to come along with a better explanation for the motion of the hands, you would be forced to update your model.     Our atomic model has much in common with the imaginary watch from the above example.  We can&apos;t base our model on actual observations of atoms, because they are too small to be seen with our most sensitive instruments.  Instead, we must come up with a model of an atom that can account for and explain observations that we can actually see.  As new observations are made, we are forced to update our model to accommodate them.  As a result, our model of the atom has evolved over time, and we must accept the fact that it is likely to change again in the future.
