Imagine that you are collecting contributions door-to-door to raise money to pay for programs to help teen mothers stop smoking when they are pregnant.

As a result of smoking when pregnant, you know that low birth weight occurs, and babies are often born premature.

You realize that you will get more, and larger, donations if you lie and say you are collecting for medical help to premature babies.

Always Usually Sometimes Rarely Never

Is it wrong to lie, even if your motivationor cause is a good one?

Or do the ends justify the means?

The War Continues• Battle of Midway

– Major turning point in the Pacific Theatre– Ended the Japanese Naval superiority in the Pacific– Morale boost, but not enough

• Although the war ends in Europe in May 1945, in some ways it was getting worse in the Pacific Theatre.– Desperate, and unwilling to surrender, the Japanese pilots began dive-

bombing Navy vessels when they would run out of fuel or ammo…– They thought this sacrificial death would resurrect the old spirit that had

once saved them from defeat from the Chinese/Mongols called the kamikaze.

• US supply lines were stretching thinner and thinner as they neared the island of Japan (explain)

• Morale = 50/50 (explain)• 4 years of fighting had taken its tole…Will we be able to win?• Invasion?

Albert Einstein’s Letter to FDR Concerning the A-Bomb

The Manhattan Project

Three Phases– Phase One - Data

• Scientist at work in labs (Los Alamos, NM) preparing data on how to split atoms, and how to get the “most bang for their buck”. Wanted to “clean sweep” an area 25sq miles.

– Phase Two – Mechanics• Engineers at work to get an airplane big enough to carry the

“gadget” deep into Japan / Military to get close enough to Japan to launch the aircraft.

– Phase Three – Resources• Oak Ridge, Tennessee uranium mine where the supplies

needed to make the bomb were being dug out of the ground and sent to Los Alamos.

At the time of the bombing, Hiroshima was a prosperous city of nearly 320,000. The bomb exploded almost directly over the center of the city. Two square miles of the city were completely leveled by the bomb, and the intense heat generated by the explosion started fires as far as two milesfrom ground zero.

Some shadows were cast by people caught by the explosion.   The circular grey patch on the steps is a shadow formed by a woman who was sitting there waiting for the bank to open for business.

She was just a junior high school girl,

only 14 years old....
