Q1. Draw a neat and properly labelled diagram of the human brain. Label the cerebrum, cerebellum, and medulla oblongata, and describe one major function of each.
Q2.Explain how the cerebrum, cerebellum, and medulla work together when a student reads a textbook, writes notes, maintains body posture, and continues breathing normally.
Q3.During an inter-school football match, a player observes the ball, decides to pass it, runs toward a teammate, maintains balance while kicking, and continues breathing rapidly throughout the game. Explain the role of the cerebrum, cerebellum, and medulla in coordinating these

Answer the following:
How many students identified the brain parts correctly?
Calculate the percentage of students who answered correctly.
Calculate the percentage of students who answered incorrectly.
Suggest one reason why students may confuse the functions of these brain parts.
Q3.Read the following situation:
During the school annual function, a student walks confidently onto the stage, remembers the speech, speaks clearly, maintains body balance while moving, and continues breathing normally throughout the performance.
Based on your understanding of the brain:
