Below are the process instructions for the students. I give my students 5 days in class to work on this project. The students have access to a computer and I generally make this due on a Monday. This is aimed at high school juniors. I have assigned students to groups and I have let them choose their own groups. But have worked very well, with no noticeable differences in grades.

The teacher should be
comfortable with Power Point, because even students who think they know what
they are doing have questions.

To accomplish the task of
understanding the history of the atom, you will need to do research to discover
what has led us to our current model of the atom. The final product pf each
team will be either a Power Point presentation or a book. *(If your team has another idea on how to present your findings, please
talk to me about it.)*

1.
First
you’ll be assigned to a team of 3 or 4 students.

2.
Each
team member is expected to contribute equally to the project.

3.
Each
team will decide among themselves as to what each team member is going to do. *Remember that each person on the team is
expected to understand all the parts of atomic history, not just the part they
researched.*

4.
Each
team will be expected to present their project to the class.

One way to organize your
information is by scientist:

· Democritus

·

· Thomson

·

· Bohr

· Schrödinger

Some questions that might help you get
started:

**In
the Beginning**

¨
Who came up
the term atom?

**Democritus** (when? who? chemist, physicist, mathematician,
teacher, philosopher, etc.)

¨
What was the
main difference between Democritus and “the others” that came after
him?

¨
What part did
Aristotle have in the atomic development?

**Dalton** (when? who? chemist, physicist, mathematician,
teacher, philosopher, etc.)

¨
What is the
difference between a model and a theory?

¨
What was
Dalton’s atomic theory?

¨
What was his
atomic model?

¨
What did he
say about compounds and chemical reactions?

¨
What was the
problem or issues with this model?

**Thomson** (when? who? chemist, physicist, mathematician,
teacher, philosopher, etc.)

¨
What was his
model?

¨
What did it
contain?

¨
Did his model
have a special name?

¨
What particles
does his model have?

¨
What was the
problem or issues with this model?

**Rutherford** (when? who? chemist, physicist, mathematician,
teacher, philosopher, etc.)

¨
What was his
model?

¨
What led him
to make his theory?

¨
What
experiment did he do and why was he so astonished?

¨
What was
significant about his discovery?

¨
What particles
does his model have?

¨
Who discovered
the proton?

¨
What was the
problem or issues with this model?

**Bohr** (when? who? chemist, physicist, mathematician,
teacher, philosopher, etc.)

¨
What was his
model?

¨
How did he
explain the main problem with Rutherford model?

¨
How are the
energy levels thought of?

¨
What does
quantized mean?

¨
What is an
orbit?

¨
Can electrons move
from energy level to energy level?

¨
What was the
problem or issues with this model?

**Schrödinger** (when? who? chemist, physicist, mathematician,
teacher, philosopher, etc.)

¨
What was his
model?

¨
How does this
model describe the atom?

¨
Why is it
better than the Bohr model?

¨
What is an
orbital and how is it different than an orbit?

Below are links to websites
that you will help the students complete this project. Many of the websites
contain more information than just one topic. In the classroom are various
chemistry textbooks that you might find helpful and of course, you may use your
chemistry textbook. Also, a copy of my notes from last year will be available
for you to look at. But, no one source will give you all of the information you
need. So, you will have to use a variety of resources to complete this project.
In fact, you want to look at more than one source in order to not miss
important information and to verify the accuracy of the information.
