“And one cried unto another, and said, Holy, holy, holy, is the Lord of hosts: the whole earth is full of his glory.” ~ Isaiah 6:3
A science teacher teaches about two things and two things only.
Matter & Energy
The entire universe made of these two things. Specifically, anything tangible is matter.
Matter is made of atoms, the smallest identifiable piece of matter related to a chemical.
A science teacher often teaches of atoms and how atoms act. Different atoms have different personalities.
Some examples include:
Uranium-238 is radioactive and used for energy and weaponry.
Potassium-32 is used to treat and detect cancer.
Helium-4 is light and able to fill party balloons.
They are all able to do these things because of their structure. Atoms are made of sub-atomic particles (protons, neutrons, and electrons), and sub-atomic particles are made of more sub-atomic particles called quarks and so, so, on.
Every time you change the structure…
