Homo Erectus
Homo erectus is an extinct species of early human that lived during the Pleistocene period, approximately 1.9 million to 70,000 years ago. They are believed to be one of the first human species to use and control fire.
Physical Characteristics
- Cranial capacity ranging from 650cc to 1250cc
- Thick skull with prominent brow ridges
- Robust and muscular build
- Shorter stature compared to modern humans
Behavior and Technology
Homo erectus is known for their advanced tool-making abilities and the control and use of fire. They are believed to have used fire for cooking, warmth, and protection.
Migration and Habitat
Homo erectus is thought to have migrated out of Africa and spread to regions across Asia and Europe. They adapted to a variety of environments, including savannas and woodlands.

Concepts of Physical Science (SB1, SB2, SB3, SB4)
The student demonstrates an understanding of the structure and properties of matter by describing atoms and their base components (i.e., protons, neutrons, electrons).
The student demonstrates an understanding of the interactions between matter and energy and the effects of these interactions on systems by recognizing that atoms emit and absorb electromagnetic radiation.
