Evolution

• If there was no iron we could not have evolved in this way

• Hemoglobin is made up of iron

• Hemoglobin carried oxygen in our blood

• Iron played a big role in our evolution

Stars Life Cycle

• Live for billions of years

• Large stars become black holes

• Small stars become white dwarfs

• Explosion sends elements all around the universe

• When a star dies it creates a supernova

• Can no longer do nuclear fusion

• Dies when it reaches a very high temperature

BIG BANG

Life

• The stars are our origin

• Carbon, iron, all elements of periodic table

• The elements we rely on originated from the stars

• Would not have been possible without the elements from the stars

Elements

• Without the elements from the stars we could not live

• Earth has an iron core because of this

• Spread around the universe because of supernovas

• Created inside the stars

Simple Matter

he only elements evident straight after the big bang

Lithium

• Helium

• Hydrogen

• Simple atoms

Galaxies

They consist of billions of stars

• They explode and our sun and solar system is created

• Clumps get larger and larger and hotter

• Clumps of matter join together

Stars

• Gives off energy in form of heat and light

• Nuclear fusion occurs

• Dense enough to have nuclear reactions

• Large bodies of helium and hydrogen

• Billions of years before galaxies

Hydrogen Cloud

• Huge balls of gas became stars

• Created a huge ball of gas

• Was the whole universe
