3. Fireworks Sounds
Narrow tubes of
fireworks create
pressure that releases a
long, high-pitched
noise
Short,thick tubes make
blunt, deep sounds

4. Electron States
Electrons begin at ground state
As the firework explodes the electrons
jump to excited state
When the electrons are jump back
down from the excited state back to
ground state the electrons emit light

5. Sparking Effects
Iron
Titanium
Antimony
Phosphorous

6. Dangers
Fireworks are very
unpredictable
Chemicals can be
exposed to someone
during explosions
Also, fire can be a hazard http://w8themes.com/wp-

7. Pollution
Gases are released from explosion and can be
deadly to humans if consumed
Carbon Monoxide and Particular Matter are
hazardous to the environment
These gases are creating large holes on the
ozone layer
