Lesson Plan/Activity
Protect Your Brain, Grades K-5
Who this is for:
Background
The brain and spinal cord make up the central nervous system (CNS), and the CNS regulates everything that we do. It controls all of our motor and respiratory functions, mediates our senses (sight, smell, hearing, taste, touch), and allows us to form memories and process complex thoughts and emotions. This important system is highly sensitive to injury, but a few properties exist to help protect it, one of which is cerebrospinal fluid (CSF).
This popular and engaging Mr. Egghead activity teaches kids the importance of our two levels of protection for the brain—the skull and the cerebrospinal fluid. The raw egg in this exercise represents our brain while the specimen cup is our skull. One “brain” will be surrounded by water, which acts as the cerebrospinal fluid cushion, while the other will lack this protective barrier. Student volunteers will be asked to demonstrate the significance of the CSF in keeping the brain safe during sudden impact to the head.
Student Objectives
- Learn about the ventricular system.
- Discover the various protective factors for the brain.
- Understand the importance of providing extra protection for such a sensitive and important organ.
