This Grade 4 Science worksheet introduces the main parts of the eye and ear and the jobs each part performs. Students learn how the pupil controls light, how the lens focuses images on the retina, and how sound waves travel from the outer ear to the eardrum and inner ear. Sentence correction, fill-in-the-blank, and short answer activities help Grade 4 learners build clear, accurate science vocabulary about the senses.

Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
The pupil are the white part of the eye that protects the inside.

Rewrite: The eardrum vibrates when sound waves hit it inside the middle ear.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. Light enters the eye through an opening called the pupil in the center of the iris.
2. The lens of the eye focuses light onto the back of the eye.
3. Sound waves cause the eardrum to vibrate inside the ear canal.
4. The inner ear holds tiny bones and the cochlea that turn vibrations into nerve signals.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. What is the job of the retina in the eye?
The retina sits at the back of the eye and detects light, turning it into signals the brain can understand as images.
2. How does the outer ear help us hear sounds?
The outer ear collects sound waves and funnels them down the ear canal toward the eardrum.
