Atoms Lab
In this lab you will try to create life sized models of atoms. Construct your
model by cutting a 28 centimeter strip of paper in half as many times as
you can. If you can cut the strip of paper in half 31 times you will end up
with a piece of paper the size of an atom. Is there anything smaller? Yes,
the size of an atom nucleus would take about 41 cuts!
Materials : 1 strip of paper 28 cm long
1 pair of scissors
Tape
Procedure:
1. Take your strip of paper and cut it into equal halves. You can’t turn the paper. You will
always cut in the same direction.
2. Cut ONE of the remaining pieces of paper into equal halves.
3. Continue to cut the strip into equal halves as many times as you can. Again, only cut in one
direction. You should end up with a thin rectangle!!!
4. Tape your final piece onto this paper.
Final Piece

How far did you get? Here are some comparisons to think about!
Cut 1 = 14.0 cm = 5.5" = Child's hand, pockets
Cut 2 = 7.0 cm = 2.75" = Fingers, ears, toes
Cut 3 = 3.5 cm = 1.38" = Watch, mushroom, eye
Cut 4 = 1.75 cm = .69" = Keyboard keys, rings, insects
Cut 6 = .44 cm = .17" = Poppy seeds
Cut 8 = 1 mm = .04" = Thread. Congratulations if you’re still in!
Cut 12 = .06 mm = .002" = Microscopic range, human hair
Cut 14 = .015 mm = .006" = Width of paper, microchip components
Cut 18 = 1 micron = .0004" = Water purification openings, bacteria
Cut 24 = .015 micron = .0000006" = Electron microscope range, membranes
Cut 31 = .0001 micron = .0000000045" = The size of an Atom!
Analysis and Conclusions
1. How many cuts were you able to do? _______ What was the highest number of cuts in the
class?______________
2. How could you have made even smaller cuts? ____________________________________
__________________________________________________________________________
3. Could we ever cut something in half so much that it would just disappear? Why or why
not?_______________________________________________________________________
__________________________________________________________________________
4. Atoms are so small that if you lined 50,000,000 (50 million) of them up in a row, they would
reach about a centimeter. How many atoms would you have to line in a row to reach
across your hand (10 cm)? Show your work. _____________________________________

The ATOMS FAMILY
 Use the information in the story to fill out
The Atoms Family Album.
In the center of Matterville, there is a place
called the Nucleus Arcade, where two members of
the Atoms Family like to hang out. Perky Patty
Proton, like her sisters, is quite large with a huge
smile and eyes that sparkle (+). Patty is always
happy and has a very positive personality. Nerdy
Nelda Neutron is large like Patty, but she has a
boring, flat mouth and eyes with zero expression
(o). Her family is very apathetic and neutral about
everything. Patty, Nelda, and their sisters spend all
their time at the arcade.
Around the Nucleus Arcade, you will find a
series of roadways that are used by another
member of the Atoms Family, Enraged Elliott
Electron. Elliott races madly around the Arcade on
his bright red chrome-plated Harley-Davidson. He
rides so fast that no one can be sure where he is at
any time. Elliott is much smaller than Patty and Nelda and he is always angry because these
bigger relatives will not let him in the Arcade. He has a frown on his face, eyes that are
squinted with anger (-), and a very negative attitude.
The Nucleus arcade is surrounded energy streets where the Electron brothers ride. The
first energy street can hold only two Electron
brothers. The second energy street, called the
Energy Freeway, can hold 8 electrons. The third
energy street, called the Energy Superhighway, can
hold 18 of the electron brothers.
The Mood of Matterville is stable as long as
each negative Electron brother is balanced out by
one positive Proton sister. The number of residents
in Matterville depends on the Proton and Neutron
families.

History of the Atomic Theory
Atomic Models
Models are often used for things that are too
small or too large to be observed or that are
too difficult to be understood easily
In the case of atoms, scientists use large
models to explain something that is very
small
Models of the atom were used to explain data
or facts that were gathered experimentally.
John Dalton
The “Solid Sphere” Model
All elements are
composed of
“uncuttable” particles.
Atoms of the same
element are the same
Atoms of different
elements are different.
Early Models of the Atom
Democritus and the Greeks
Universe was made of empty
space and tiny bits of stuff
Called these tiny bits of stuff
atomos
Atoms could not be divided
J. Joseph Thomson
“Plum pudding” model
“Solid Sphere”
Model
Atom made of a
positively charged
material with the
negatively charged
electrons scattered
through it.
Ernest Rutherford
The “Planetary” Model
Niels Bohr
Borh or “Orbital” Model
“Planetary” Model
Mostly empty space
Small, positive
nucleus
Contained protons
Negative electrons
scattered around the
outside
James Chadwick
Discovered the neutron
Electrons move in
definite orbits
around the
nucleus like the
planets of the
solar system.
Werner Heisenberg
The “Electron Cloud” Model
Electrons travel around the
nucleus in orbits.
Cannot know where
electrons will be at any
given moment.
Electrons travel so fast,
they appear to form a
“cloud” around the nucleus.

The Best Element Flyer
1. You are trying to convince the class that your element is the best. Your element is so
awesome, so incredibly cool, that you want everyone to vote for it as official Class Element!
2. To have a successful campaign, your element must have an informational flier with a catchy
slogan. You need to convince the general population of the classroom that they should vote
for your element.
3. First, do some research on your element (Here are some helpful web-sites,
http://snurl.com/rydcx, www.chem4kids.com, http://snurl.com/rydbu). Make sure you get
the following information:






Number of protons
 Nonmetal, metal, or metalloid
Number of neutrons
 Uses
Number of electrons
 Any other interesting information
Melting Point
(who discovered it, how it got its
Boiling Point
name, interesting properties, etc.)
Phase (solid, liquid, or gas) at
Room Temperature
4. After getting all this information, you will make an informational flier about your element
that is the size of a regular sheet of paper. You want this flier to be an eye-catcher! Make
sure all the above information is on your flier. You can use your artistic skills or the
computer; just make sure it compels people to want to vote for your element!
5. You also need a cool slogan at the top of your flyer. This slogan needs to convince people
that your element is awesome. Be creative with the information you researched. For
instance, if you had Hydrogen, you could write, “Hydrogen is #1!” since it is the first
element on the periodic table. (Don’t use my example!)
