1. Weapons of WWI

2. Flamethrower invented by Germans shot a stream of gas/oil that ignited in the air used to chase men out of trenches very unstable

3. Flamethrower

4. Machine Guns invented by Americans shot a steady stream of bullets reason for building trenches. Early machine guns needed 4-6 men to work them and had to be on a flat surface. They had the fire-power of 100 guns.

5. Large field guns had a long range and could deliver devastating blows to the enemy but needed up to 12 men to work them. They fired shells which exploded on impact.

6. Poison Gas invented by Germans used to harm a large amount of men at once (gas masks) main gas used was mustard gas gas was unpredictable and unstable

7. Chlorine gas causes a burning sensation in the throat and chest pains. Death is painful - you suffocate! The problem with chlorine gas is that the weather must be right. If the wind is in the wrong direction it could end up killing your own troops rather than the enemy.

8. Mustard gas was the most deadly weapon used. It was fired into the trenches in shells. It is colourless and takes 12 hours to take effect. Effects include: blistering skin, vomiting, sore eyes, internal and external bleeding. Death can take up to 5 weeks

9. Soldier with Mustard Gas burns

10. Skin exposed to mustard gas…

11. Mortars A mortar is essentially a short, stumpy tube designed to fire a projectile at a steep angle (higher than 45 degrees) so that it falls straight down on the enemy. designed by the Chinese Lobbed shells into air to go directly into trenches.

12. Zeppelins Zeppelins (blimps) were first used to scout and bomb cities (London and E. England - did little damage but scared people) was used during the early part of the war in bombing raids by the Germans. They carried machine guns and bombs. They were abandoned because they were easy to shoot out of the sky. Filled with hydrogen gas (easy to blow up)

13. Airplanes Planes were used to scout the enemy positions later were armed with machine guns and bombs

14. Tanks Invented by the British Used for the 1 st time in WWI huge metal platforms armed with canons and machine guns used to attack trenches w/o endangering troops.

15. The first tank was called 'Little Willie' and needed a crew of 3. Its maximum speed was 3mph and it could not cross trenches The more modern tank was not developed until just before the end of the war. It could carry 10 men, had a revolving turret and could reach 4mph.

16. Submarine Torpedoes mainly used by Germans to attack Allied shipping The Germans used torpedoes to blow up ships carrying supplies from America to Britain.

18. Trenches
