Notable Points for Students
Planets can be categorized based on their composition. These include:
1. Terrestrial or Rocky Planets: They are mercury, venus, earth and mars. They are called terrestrial or rocky planets for the following reasons:
They have a rocky and compact surface.
They have no rings around them.
They have a few natural satellites.
They rotate slowly around their axis.
2. Gas or Jovian Planets: They include jupiter, saturn, uranus and neptune. They have the following features:
They are called jovian planets because they are bigger in size when compared to earth.
They are composed mainly of hydrogen and helium gas, hence the name 'gas planets' or 'gas giants'.
They rotate rapidly.
They have many satellites.
They have rings around them.

Geography
The following rules are required for a body to become classified (or regarded) as a planet:
It must orbit the sun.
It does not orbit another planet. This means that it must not be a satellite.
It must have sufficient mass which accounts for its self-gravity.
It must assume a nearly round shape.

Physics
Force can be balanced or unbalanced.
When forces from different directions act on an object and consequently bring about the object's motion, then such forces are unbalanced.
Conversely, if theses forces bring about zero motion (static position or no movement) on the object of reference, then it's a balanced force.
In summary,
An apple hanging on a tree (without any form of movement) has a balanced force.
An apple falling from a tree has an unbalanced force.
Physics

Chemistry
John Dalton is an English chemist who brought clarity into the composition of matter and the basis for their chemical reactions.
Below are Dalton's Atomic Theory:
All matter consists of tiny indivisible particles called atoms.
Atoms of the same element are identical to each other in every aspect because they have the same shape and mass, while atoms of different elements are different in all respect.
Atoms are indestructible and can neither be created nor destroyed.
Atoms of different elements can combine with each other in simple whole number ratios to form compounds.
Atoms of the same element share similar physical and chemical properties. They can also combine in more than one ratio to form two or more compounds.
Meanwhile, understand that the above theories of John Dalton had been modified.

Chemistry
All human beings are entitled to a fundamental, inalienable, non-discriminatory, indivisible and universal rights which is termed human rights.
These fundamental rights of humans will allow each and every one of us to live in freedom, equality, fairness, respect, peace and justice.
