Structure of the Atom
Lesson
An E3T model lesson for the MISD
UDL prototype project
Coin Exploration

Using the various materials in front of
you, explore the coins with your table
partners.

Make notes of the similarities and
differences between various coins.

You will have about 5 minutes.
Chemistry Song

While we listen to the song by Tom Lehrer, think about
the following:




What names do you recognize?
What is the list of items referring to?
What do the dates at the end refer to?
About how many items did he list?
Link to Song
Organization of Elements

The elements we heard in the song are organized
into “families” of similar characteristics.

There are 109
elements in the
current periodic
table.
Sticky Note Atoms



Protons
Neutrons
Electrons
Rules:





Protons and Neutrons in center (nucleus)
Protons spaced by neutrons
Electrons outside nucleus (as much space as possible)
Neutral atoms must have balanced charge
Electrons in levels (2 in 1st level, 8 in 2nd, 18 in 3rd)
What is the charge on a proton?

Questions before we move on?
My Favorite Element Project

Build a model of an atom with 6 or more protons.
-

Show proper placement and labeling of the protons,
neutrons, ad electrons.
Develop an explanation of the model, including:
-
How this element is used in the real world and why
you chose it.
The history of the element’s discovery.
Natural sources of the element.
Characteristics / physical properties.
•
•
Temperature at which it melts (melting point)
Temperature at which it boils (boiling point)
My Favorite Element Project

The model may be made from the materials of your choice.
Some ideas might be:
-

Legos
K’nex
Beads in wearable jewelry
Digital model
Clay / claymation
The explanation may take the form of your choice.
Examples include:
-
Podcast,
Videocast,
Digital story,
Song or rap,
Written paper.
