What is an Atomic Bomb?

It is a weapon in which an enormous amount of energy is released through nuclear fission or fusion.

They are very dangerous!! Atomic explosions can be made

through fission and fusion of Uranium-235.

Take a guess! Discuss it with

a friend.

Atomic bombs become famous

During World War II, Hitler

was developing a plan to create

the atomic bomb.

A Jewish scientist was afraid what Hitler might

do when he had the atomic bomb, so he

wrote President Roosevelt convincing him to try and beat Germany to the first

atomic bomb.

In 1942, Roosevelt

gave the ok for scientists

to start the “Manhattan

Project”, the search for the atomic bomb

in science.

Albert Einstein

even signed

the letter to

Roosevelt!

Even after Germany had given up, America pursued on. After

the first test, the scientists realized just how much power

they were working with was far more than they had originally

imagined.

Atomic History Con’t.

After Hitler’s suicide, the

scientists were sure that such a weapon was no

longer necessary.

The scientists wrote a strong petition to the

US government expressing their

opinion.

He then gave the order for the bomb to be dropped.

Unfortunately, President

Truman ignored their request and insisted

that their work had not gone to

waste.

WOW!

How are atomic bombs made? (Fusion)S

tep

1 Isotopes of hydrogen are smashed together at high pressures.

Ste

p 2 This creates helium, and releases a LOT of energy.

Ste

p 3 The

energy can be used for weaponry.

How are atomic bombs made? (Fission)S

tep

1 1 neutron splits an atom. S

tep

2 After it’s split, another neutron is released.

Ste

p 3 Then that

neutron splits another, until all the atoms are split.

Watch this fission movie!

Fusion Movie!! Nuclear Fusion can also be found in

the sun!!

So why do I care?

Atoms, which are so unbelievably small that they needed a new measurement to express their size, are able to create a weapon that can cause:

Are atomic bombs dangerous/illegal?

The American government has a special license to use nuclear bombs.

The radioactive materials needed to build an atomic bomb are illegal to obtain, so building one is as well.

Also, by having an atomic bomb, you can hurt others. So yes, it’s pretty much illegal.

What are they used for?

Atomic bombs are used simply for weaponry and war means.

However, some are built completely for study.
