Electric Current
Michael Faraday discovered that when a wire carrying an electric current is placed next to a single magnetic pole the wire will rotate. This led to the development of the electric motor. He was also the first person to produce an electric current by moving a wire through a magnetic field. -
Theory of Evolution
Charles Darwin's theory of evolution he argued all organisms evolve or change very slowly overtime; organisms evolve or change slowly over time, this allows species to survive in its environment. If a species doesn’t adapt it may become extinct. -

Theory of Relativity
Albert Einsteins theory of relativity explains the relationship between speed,time, and distance. This theory states the speed of light will remain the same regardless of how fast someone or something is moving toward or away from it. This became the foundation for modern science. -

Antibiotics
Alexander Fleming discovered the first antibiotic, penicillin which he grew in his lab using mold and fungi. -
Double Helix Dna Structure
James Watson from the u.s. and francis crick of England discovered the double helix structure of dna. This is made up of two strands that twist around each other and have an almost endless variety of chemical patterns.
