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
