Democritus suggests the world is made up of atoms

# data[].attributes.body
In 430 bce, Democritus first discovered his atomic theory. He believed that atoms were uniform, solid and incompressible and that they moved in infinite numbers in space until stopped. His theory was significant because it led to more scientific discovery about the atomic universe that is crucial knowledge in science today.

Nicholas Copernicus shows planets orbiting the sun

# data[].attributes.body
In 1543 Nicholas Copernicus first showed his theory of earth and other planets orbiting the sun. It took more than a century for his theory to be accepted. However, this discovery, once accepted, was important because we learned more about space and how the solar system works leading to more scientific discovery about our universe which was equally important in our understanding of it.

In 1609 Galileo first invented the telescope. His invention was important in connection with Nicholas Copernicus's theory (as mentioned on previous padlet) because it allowed people to observe other planets in our solar system and it helped confirm many scientific theory's about space.

William Harvey shows that the heart pumps blood around the body

# data[].attributes.body
In 1618 William Harvey showed that the heart pumps blood around the human body. This scientific discovery was crucial for mankind because it helped lead to understanding about the human body. Understanding the human body is crucial because it allows us to help ourselves when we get injured or sick.

In 1662 the dodo bird became extinct. I think this was important because it showed people that animals don't stick around forever and that they can become extinct. I think it helped us realize to care and be more mindful of nature.

In 1687 Issac Newton made his infamous discovery of gravity. It was a crucial discovery because it led to an understanding of how gravity works. Once we understood that, it became easier to create inventions that defied gravity like the airplane.

Antoine Lavoisier shows air contains oxygen and nitrogen

# data[].attributes.body
In 1778 Antoine Lavoisier first recognized that air contained oxygen. This scientific discovery was important because we breathe and survive on air everyday and it helped to show why, and now scientists understand more, not only about air but about our human bodies and why we need it.

Edward Jenner vaccinates against small pox

# data[].attributes.body
In 1796 Edward Jenner first discovered a cure for small pox. However, In 1798 The first vaccine was developed. This discovery saved many lives of the people suffering from small pox and still helps people today with either immunity or treatment.

Charles Darwin publishes his theory on evolution

# data[].attributes.body
In 1859 Charles Darwin first published his theory of evolution. He stated that all species of organisms arise and develop through the natural selection of small inherited variations that increase the individuals ability to compete, survive and reproduce. This theory is important for many reasons, firstly it helps us understand our roots and (for example) why we have opposable thumbs. Secondly, it connects us more with nature and helps us to further evolve with science.

In 1879 Thomas Edison invented the first electric light bulb. The first lightbulb he created was only able to burn for a few short hours but it further evolved from thereon. I think this discovery was super important because without it we would only be able to work with the light of day. The light bulb helps us see better, and lets us work after the sun goes down.

Albert Einstein discovers theory of relativity

# data[].attributes.body
In 1916 Albert Einstein discovered his theory of relativity. He discovered that the laws of physics are the same for all non-accelerating observers. This theory is important because it helps scientists better understand the laws of physics. This understanding helps them create inventions that work with those laws.

In 1917 Ernest Rutherford split the atom. Before he split the atom, scientists thought the atom was the smallest thing, however they were wrong. I think this discovery was important because it gave us more knowledge on the fundamentals of material. It helped us expand the scientific world with the knowledge that there was more to dicover.

In 1953 Watson and Crick discovered a human DNA structure. This was important because it showed the connection between mother, father and daughter/son. It also helped us understand the structure of human biology.

In 2021 the James Webb Space Telescope was launched. This scientific telescope is important because its purpose is to find the first galaxies formed in the early universe, and to see starts forming planetary systems. Nothing has been discovered yet, however this is super important in discovering more about the universe we live in and potentially finding other galaxies or life forms.
