The RMS Titanic struck an iceberg on its maiden voyage from Southampton to New York in April 1912 and sank within hours, resulting in the deaths of over 1,500 people aboard. The Titanic was ill-prepared for an emergency, with lifeboat capacity for only about a third of those onboard. As the ship sank bow-first into the freezing North Atlantic waters, chaos ensued in the launching of the vastly under capacity lifeboats, many leaving only half-full, while over 1,500 passengers and crew perished in the icy water from hypothermia or drowning.

Titanic survivors
1. RMS Titanic – who survived?
The RMS Titanic was a passenger liner that
struck an iceberg in the north Atlantic Ocean
on her maiden voyage from Southampton,
England, to New York City, United States,
and sank on 15 April 1912.
2.
3. At 11.40 pm, a lookout spotted an iceberg immediately ahead of Titanic and alerted the bridge.
First Officer William Murdoch ordered the ship to be steered around the obstacle but it was
already too late; the starboard side of Titanic struck the iceberg, creating a series of holes below
the waterline.
4. It soon became clear that the ship was doomed. Titanic began sinking bow-first, with water
spilling from compartment to compartment as her angle in the water became steeper.
5. Those aboard Titanic were ill-prepared for an emergency. There was only enough space in the
lifeboats for a third of her maximum number of passengers and crew. The officers did not know
how many they could safely put aboard the lifeboats and launched many of them barely half-
full.
6. The severed bow section headed for the sea bed, while the stern remained afloat for a few
minutes longer, rising to a nearly vertical angle with hundreds of people still clinging to it.[134]
At 2.20 am, the stern sank, pitching the remaining passengers and crew into lethally cold water
with a temperature of only 28 °F (-2 °C). Almost all of those in the water died of hypothermia or
cardiac arrest within minutes.[135] Only 13 of them were helped into the lifeboats though these

10. Titanic Facts and Figures
The Titanic set sail on its famous journey at 12:00 noon on April 10, 1912. The first stop
was Cherbourg, France. After picking up passengers, the Titanic once again set sail at
8:10pm toward Queenstown, Ireland. With 2227 people on board this great vessel left
Queenstown toward New York at 1:30pm on Thursday April 11, 1912. The Titanic sailed
on Friday April 12 and Saturday April 13 in clear weather. On Sunday, April 14 at
11:40pm, the Titanic struck an iceberg. 12:00am the captain was told that the Titanic
would only stay afloat for a couple of hours. At 2:20am Monday April 15, 1912 the Titanic
sank into the sea.
Using the above information, answer the following questions.
1. How long was the Titanic at sail from the time it first set sail until it finally sank?
2. There were 2227 passengers on board the Titanic at the time that it sank. 14 of the
lifeboats held 65 passengers each, 2 were emergency cutters which held 40 people
each and 4 were collapsible boards which held 47 people each. How many people
would all of these lifeboats hold?
3. Only 705 people survived the sinking of the Titanic. How many more people could
have been saved?
4. How many more lifeboats were needed to save all people aboard the Titanic?
11. Drawing dual bar charts
This a breakdown of the passengers on the RMS Titanic. Find the totals for each class.

2nd class 168 93 24 285
3rd class 462 165 79 706
Total 805 402 109 1316
This a breakdown of the passengers who survived the sinking. Find the totals for each class.
Men Women Children Total
1st class 57 140 5 202
2nd class 14 80 24 118
3rd class 75 76 27 178
Total 146 296 56 498
We’re going to draw bar charts comparing the number of passengers who were on the
Titanic, and the number who survived.
