The brain is a complex and vital organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It controls and coordinates actions and reactions, allows us to think and feel, and enables us to have memories and learn from our experiences.
The human brain is divided into three main parts: the cerebrum, the cerebellum, and the brainstem. The cerebrum is the largest part and is responsible for higher brain functions such as thinking, perceiving, and planning. The cerebellum is located at the back of the brain and is involved in coordination and balance. The brainstem connects the brain to the spinal cord and controls basic functions such as breathing and heart rate.
Functions of the Brain
The brain performs a wide range of functions, including:
Sensory processing: The brain receives and processes information from the senses, such as sight, hearing, taste, smell, and touch.
Movement control: The brain coordinates voluntary and involuntary movements of the body.
Emotion and behavior regulation: The brain plays a key role in regulating emotions and behaviors.
Memory and learning: The brain stores and retrieves information, and enables us to learn from our experiences.
Earth/Space Science: Students will use scientific skills and processes to explain the chemical and physical interactions (i.e., natural forces and cycles, transfer of energy) of the environment, Earth, and the universe that occur over time.
Earth History: Explain how sedimentary rock is formed periodically, embedding plant and animal remains and leaving a record of the sequence in which the plants and animals appeared and disappeared.
Explain how sedimentary rock buried deep enough may be reformed by pressure and heat and these reformed rock layers may be forced up again to become land surface and even mountains.
