Human Eye


Human Eye explores the inner workings of the eyeball and how each part works together to help us see. Students will be able to explain the different parts and their unique functions. They will also learn why humans can only see visible light waves and not other types of waves.

You may choose to incorporate the ideas from the “Options for Lesson” section of the classroom procedure page, which lists suggestions for additional activities or tasks. One option is to assign students to research eye problems, eye color variations, and other things that relate to eyes in general.

What our Human Eye lesson plan includes

Lesson Objectives and Overview: Human Eye explores the different parts and functions of eyes. Students will discover how this part of the body allows us to process light and visualize color. They will learn about tears as well and how the lacrimal glands release moisture for a number of different reasons. This lesson is for students in 4th grade, 5th grade, and 6th grade.

Classroom Procedure

Every lesson plan provides you with a classroom procedure page that outlines a step-by-step guide to follow. You do not have to follow the guide exactly. The guide helps you organize the lesson and details when to hand out worksheets. It also lists information in the yellow box that you might find useful. You will find the lesson objectives, state standards, and number of class sessions the lesson should take to complete in this area. In addition, it describes the supplies you will need as well as what and how you need to prepare beforehand. For this lesson, you will need colored pencils and small flashlights for the activity portion.

Options for Lesson

The “Options for Lesson” section contains several ideas for additional activities and exercises to add to the lesson if you want to extend it or have extra time. One idea is to go through the content pages before distributing the activity. You could choose to assign the practice page as the homework and vice versa, using the crossword as an in-class assignment. Another option is to assign students to research other aspects about eyes, such as eye problems, color variations, color-blindness, and so on. You could let students choose or decide for them which topic they should research. Students could even create presentations to show the class that showcase what they learned during their research.

Teacher Notes

The paragraph on this page gives you a little more information on the lesson overall and describes what you may want to focus your teaching on. It reminds you to stress the importance of eye safety and also suggests looking at the “Options for Lesson” section for more ideas. The blank lines are available for you to write out any thoughts or ideas you have as you prepare.


The Human Eye lesson plan includes three worksheets: an activity worksheet, a practice worksheet, and a homework assignment. Each worksheet reinforces the lesson concepts and provides students the opportunity to showcase what they learned. Refer to the guide on the classroom procedure page, which describes when to distribute each worksheet to the class throughout the lesson.


Students will work with a partner for much of the activity, which focuses on various aspects of sight and the eyes in general. First, students will learn a little about depth perception using pencils. They must try a few times to touch the eraser ends together with one eye closed then with both open. Then they will write what they noticed in the space provided. Next, each partner will take turns shining light in the other person’s eyes with a flashlight and see what happens to the pupil.

Then students will take turns drawing pictures of their partner’s eye, including as much detail as possible. The next section focuses on reflexes. Each person will move their hand quickly and closely (without touching) to their partner’s face and write down what happens. Finally, students will discuss times that their eyes teared up or became watery. They will compare their stories to see what they might have in common and write down why they think their eyes make tears.


For the practice worksheet, students will review a diagram of the side view of an eyeball. Using the terms in the word bank at the top of the page, they will label the nine parts of the eye. You may choose not to allow students to use the content pages for reference as they work on this worksheet since the diagram comes directly from those pages.


The homework assignment requires students to complete a crossword puzzle based on what they learned. There are 19 total clues to solve. Again, you can decide whether or not you want to allow students to refer to the content pages for help to complete this assignment.

Worksheet Answer Keys

If you choose to administer the lesson pages to your students via PDF, you will need to save a new file that omits these pages. Otherwise, you can simply print out the applicable pages and keep these as reference for yourself when grading assignments.

Upper Elementary or Middle school Ear and Eye Lesson

These plans are self-explanatory even for the child. There is sufficient material to really cover the subject without the child being drown in reading. I was impressed by the labeled images that really help. Excellent source of the material.

Wonderful Resource

This item was very classroom friendly. The reading level of the materials allowed independent comprehension from my on level and above level readers and supported comprehension for my below level readers.
