About This Chapter
Below is a sample breakdown of the Sight, Hearing and Other Senses chapter into a 5-day school week. Based on the pace of your course, you may need to adapt the lesson plan to fit your needs.
|Day||Topics||Key Terms and Concepts Covered|
|Monday|| The Eye and Eyesight: Large Structures; |
Receptors of the Back of the Eye: Retina, Rods, Cones and Fovea;
How Receptors of the Eye Conduct Information via the Optic Nerve
| The iris, pupil and cornea; |
How the eye's photoreceptors transmit information to the brain;
Functions of the rods, cones and optic nerves of the eye
|Tuesday||Anatomy of the Ear's External Structures||How the pinna and tympanic membrane transmit sound waves|
|Wednesday||The Middle Ear: Structures and Functions||The characteristics of the middle ear and the ways in which it carries sound waves|
|Thursday||How the Inner Ear Supports Hearing and Your Sense of Balance||How fluid in the ear facilitates hearing, and discovering how the ear's vestibule and semicircular canals help maintain balance|
|Friday||Taste, Touch and Smell||A look at the receptors that are responsible for these senses|
1. The Eye and Eyesight: Large Structures
Would you be able to see anything without a lens in your eye? Does the lens change shape? Does the iris? What structure gives you your eye color? Find out all of this and about things like the ciliary muscles and the cornea as we delve into this lesson.
2. Receptors of the Back of the Eye: Retina, Rods, Cones & Fovea
Find out how we see the world in color, what rods and cones are, and how camera film fits into all of this. In addition, you'll find out what the retina is and what gives you the ability to see at night.
3. How Receptors of the Eye Conduct Information via the Optic Nerve
You will learn how your eyes are able to see the image in front of you thanks to special cells called photoreceptors. In addition, these receptors have very important proteins called rhodopsin and photopsin; and all of these things work together to transmit information to your optic nerve.
4. Anatomy of the Ear's External Structures
What is the pinna? Is it the same thing as your earlobe? Does the eardrum have anything to do with the tympanic membrane? Find out as we explore all of this and other important structures involved in the sensation of hearing as sound enters your ear.
5. The Middle Ear: Structures & Functions
Your middle ear turns sound waves from the world around you into vibrations, which can be used to make nerve signals for your brain. This is a big job for the tiniest bones of your body. Learn about the little bones, or ossicles, of the middle ear.
6. How the Inner Ear Supports Hearing and Your Sense of Balance
You usually think of your ears for hearing, but did you know they also help you maintain your balance? In this lesson, you will learn about the structures of the inner ear and how they help support hearing and your sense of balance.
7. Taste, Touch & Smell: Proprioception & the Somatosensory System
How do taste, touch and smell work? Also, what is proprioception? Throughout this lesson, you'll get a detailed description on each of these remarkable senses.
