Light is a form of energy that is an essential part of our daily lives. Light regulates plant and animal growth, climate conditions, and human vision. This Web Quest focuses on the operation of the human eye. The human eye contains a lens that allows you to see. The human eye isn't perfect and often needs some human intervention to function properly. Using their knowledge, eye doctors have to improve the quality of life for thousands of people.
In this Web Quest, you will assume the role of an eye doctor in the first year of medical school. As part of your medical training, you will be investigating such things as color perception, color blindness, night blindness, and blind spots. You will need to create an anatomically correct drawing and model of the human eye.
Print out the Student Data Handbook here.
Use the links below to collect data for the following activities. Record the data collected in you Student Data Booklet.
Students will work individually to complete the following assignments:
Identify and describe the function of the major parts of the eye.
Explain how the human eye perceives light.
Take and record results from the Color Blindness Test.
Explain how the blind spot is formed.
Describe the process the human eye undergoes when seeing at night.
Draw an anatomically accurate drawing of the human eye that contains the following 9 parts: blind spot, ciliary muscles, cornea, iris, lens, optic nerve, pupil, retina, schlera.
Create an anatomically correct model of the human eye with the same 9 parts as listed above.
Each student will be evaluated on their answers in their Student Data Booklet. Refer to the Assessment Tools provided in the Student Booklet for each activity above.
After making an initial study of the human eye and its basic function, answer the following:
1) What other problems are associated with the human eye, and how are they corrected?
2) What are the more common diseases that afflict the eye?
3) What career opportunities are associated with the human eye, and what do they do?
