How to Build a Model of an Atom
1.
Use a different color of M&Ms for each of the following:
neutrons
protons
electrons
2.
Neutrons and protons are in the center (nucleus) of the
atom
3.
Electrons orbit around the nucleus
4.
There are the same number of electrons (negative charge)
and protons (positive charge)
5.
You can choose how many neutrons (no charge) you want
to have in your atom
After you’ve created your atom with M&Ms, draw your atom in
your science notebook. Label the neutrons with an N, the
protons with a P and the electrons with an E. Color the
neutrons, protons and electrons with colored pencils.
-
This is my atom – your atom will
probably have a different number of
neutrons, protons and electrons
N = neutron
P = proton (+)
E = electron (-)

Activity – rub balloon on
cloth again after each
activity to recharge
balloon!
1. Move a finger toward
the balloon, observe
and listen.
2. Bring the charged
side of your partner’s
balloon close to your
balloon; observe and
listen.
3. Put the charged
balloon on the table
and try to gently roll
it.
4. Try to stick the
charged balloon on
the wall.
5. Hold the charged
balloon above a bowl
of gelatin.
6. Hold the charged
balloon near a thin,
steady stream of
water.
Observation – record what happens
