4. Impact Brought an end to trench warfare
Thousands of tanks made contribution to British and French war effort
Still used today

5. How Machine Guns Operate
Two types of how machine guns received energy
Recoil system
Bolt locks to barrel
Stays together moving forward and back creating energy
Gas System
Pressure of exploding gas drives piston
Piston fires back a bolt to back of gun which provides energy
Both systems had cycles repeat over and over again to fire bullets continuously

6. Before and During Before World War 1 During World War 1
Two armies charging at each other in an open field with mostly single fire muskets
Stabbed at each other with bayonets
Lots of land gained at end of war
During World War 1
Machine guns kill thousands of men in an open field
Caused enemies to build trenches in order to protect themselves from machine gun fire
Gained little land since both armies were stuck in trenches and became very hard to advance

7. How the Machine Gun Helped
Led to invention of tanks and gas warfare
Made stalemates in trenches so people had to think of new ways of killing each other
Created an anti-aircraft weapon for ships and land bases
Created a weapon on airplanes instead of bombs
Were much more effective in killing masses of platoons or battalions than single firing guns

9. Gas Attack on the Western Front
Types of Poisonous Gas
Mustard Gas (C6H8CI2S):
Blistering agent
Caused skin to blister away, temporary blindness, uncontrollable watering of the eyes, and vomiting
Chlorine/Phosgene Gas:
Chocking agent
Burns or seriously damages respiratory system of whoever inhaled it
Blood Agents:
Interfered with the level of oxygen in the blood of the victim
Lessened oxygen levels killing victim of oxygen loss
VX (C11H26NO2PS):
Nerve Agent
Killed through loss of consciousness, impairment of normal breathing, and suffocating
Gas Attack on the Western Front

10. Types of Protection Against Poisonous Gas
Masks and Helmets were used by all even horses
British Hypo Helmet
Earliest protection used
Had some protection with eye pieces
Weak but broke easily
Small Box Respirator
Invented after and worked better than the Hypo Helmet
Protected whole face, eyes, and hands
Anti-Gas Chemicals
All masked were dipped in these chemicals
Consisted of sodium hyposulphite, washing soda, glycerin, and water
What to do without a mask?
All soldiers carried two masks (in case one was defective)
If without a mask, soldiers were instructed to place a urine filled cloth all over their face

11. How was Poisonous Gas Created and Used?
By scientists in labs by combining different chemicals with each other at different temperatures
Germans were the first to create poisonous gas
Used
Tear-Gas shells were fired in artillery pieces or released from canisters in the front line
Releasing gas after explosions were not effective
The explosion dispersed the gas too much making it not potent enough to do any damage
Not until the Battle of Verdun in 1916 did the explosive to gas ratio was perfected
A makeshift German gas laboratory near the front

12. Effects of Poisonous Gas
1,200,000 people were gassed in World War 1
91,200 of which died
Forced enemy to invent protection against the gases
Caused enemy to not properly follow orders
Not used in World War 2
Use of poisonous gas was banned by Germany in 1925
3.25%
96.75% 12
