Major male reproductive organs include:
Testes
Scrotum
Sperm ducts
Penis
Major female reproductive organs include:

Revision of Light and Colours
Light enables us to see.
The rainbow colours are:
🌈 Red, Orange, Yellow, Green, Blue, Indigo, Violet.
ROYGBIV
Revision of Atoms and Elements
An atom is a tiny unit of matter.
An element is a substance containing only one type of atom.
Examples include:
Hydrogen – H
Oxygen – O
Carbon – C
Nitrogen – N
Revision of the Periodic Table
The first ten elements are:
Hydrogen – H
Helium – He
Lithium – Li
Beryllium – Be
Boron – B
Carbon – C
Nitrogen – N
Oxygen – O
Fluorine – F
Neon – Ne
