multiple collisions with the iceberg the titanic s damage was not caused by a single impact with the iceberg at least six repeated collisions occurred because the ship was actually sucked into the iceberg due to a phenomenon called bank suction this occurs when a large ship passes close to another object such as a dock a ship or an iceberg the speed of a ship moving past an object creates an imbalance in water pressure the water pressure between the photo of the iceberg believed to have hit the titanic ship and object is lower than the pressure on the outside of the ship and the ship is then pulled toward the object fact while heading out to sea the titanic came too close to the new york a ship tied to a nearby dock the new york broke its mooring lines and was pulled towards the titanic but the two never collided · the tip of the iceberg is more than a saying due to the density of freshwater being less than that of saltwater icebergs float but only 1/8 is above water the remaining 7/8 is under water and can protrude posing the most danger · the average iceberg is -15 to -20 degrees c and can travel up to 3.6 kph in a very erratic path · most north american icebergs calved off freshwater glaciers in greenland and moved after being caught up in the labrador current · icebergs are usually white due to trapped air bubbles clear ice will reflect sunlight and appear blue algae causes a berg to look green brown and black icebergs are due to airborne dust and eroded soil trapped in the ice rusticles for the past nine decades saltwater and microbes have been attacking the titanic this exposes more metal to corrosive salt much of the ship is now covered in stalactite-like underwater accretions called rusticles not so unsinkable titanic expeditions building the titanic required three million rivets and the shipbuilder harland and wolff may have addressed a shortage by using substandard iron rivets not steel in the bow and stern scientists who reviewed company archives say naval experts suspect that popped rivets along six seams in the hull made the ship sink quickly the titanic was first discovered in 1985 by dr robert ballard since then rms titanic inc has conducted seven expeditions for research and artifact recovery to titanic in 1987 1993 1994 1998 2000 and 2004 workers loaded 5,892 tons of coal aboard the titanic for her maiden voyage she burned 690 tons of coal per day several thousand tons of coal remain scattered across the debris field coal locate the wreck of the titanic 52°w 43°n 51°30 w 51°w 50°30 w 50°w 49°30 w 49°w 48°30 w 48°w 42°30 n 42°n 41°30 n 41°n 40°30 n 40°n 4 locate and label the icebergs and the ship s position · icebergs reported by other ships 41º51 n 49º52 w where did it sink into the ocean 43°n 41º27 n 50º8 w 42º5 n 50º7 w 1 on your map color the ocean light blue and label it atlantic · titanic s first emergency message 41º46 n 50º14 w ocean · corrected titanic message 41º46 n 49º14 w 42°30 n · wreck site 41º44 n 49º56 w 2 color the land light green find where each of these countries are and label them ireland england france usa and canada the titanic wreck was located 12,600 feet 52°w 51°30 w 51°w 50°30 w 50°w 49°30 w 49°w 48°30 w 48°w where was the titanic going when it hit the iceberg 3 using the above map draw in the route of the titanic in red put a star where the ship sank 42°n below the surface of the atlantic ocean mt hood in oregon is only 11,230 feet high 41°30 n

word search signal flags bathtub science making metal float how can a ship made of thousands of pounds of steel plates like the titanic not only float but carry thousands of people their luggage furniture and cargo it all depends on how much water is displaced test out the principle of displacement using your body take everything out of the bathtub except the water use something to mark the level of the water on the side of the tub a piece of tape or a figure get into the tub how deep is the water now the water level goes up because your body displaces or pushes aside some of the water ships can float because their shape has been designed to displace more water than the weight of the ship take a piece of clay roll it into a ball and put it into the water what happens now take the same piece of clay and flatten it into a bowl shape place it on top of the water what happens now the clay can float the thinner and flatter shape has more space for water s buoyant force to push on so the water itself holds the clay up the clay boat displaces more water so it can float explore more what is a growler who was polar the titanic bear who was the unsinkable molly brown what does r.m.s mean which smokestack is fake learn to tie knots like a sailor check out the knot gallery at www.tollesburysc.co.uk read ruth becker s story i survived the titanic at www.nationalgeographic.com/ngkids/9607.titanic ruth was a 12 year old passenger on the titanic become a junior ice pick and track icebergs at www.uscg-iip.org/students signal flags are still used today by ships to communicate draw flags to spell out your initials see example or send a secret message to a friend www.wingood.com/flagselect.asp more cool sites www.webtitanic.net http search.eb.com/titanic www.titanic-online.com the titanic exhibit website www2.sptimes.com/titanic the sinking animation website kjm mission statement g.wiz makes science relevant technology understandable and learning an interactive adventure g.wiz is a non-profit science museum that provides unique quality museum experiences that have inspired creativity and curiosity for over 15 years at the blivas science technology center 1001 boulevard of the arts sarasota florida 34236 phone 941.309.4949 fax 941.906.7292 www.gwiz.org cymk gwiz-2136-10/08
