- As needed, submit a question to one of our instructors for personalized support.
Who's it for?
This chapter of our Middle School Life Science Tutoring Solution will benefit any student who is trying to learn about sight, hearing and other senses and earn better grades. This resource can help students including those who:
- Struggle with understanding the structures of the inner and middle ear, the eye's receptors, the optic nerve or any other topic related to the human senses
- Have limited time for studying
- Want a cost effective way to supplement their science learning
- Prefer learning about science visually
- Find themselves failing or close to failing their sight, hearing and other senses unit
- Cope with ADD or ADHD
- Want to get ahead in middle school life science
- Don't have access to their science teacher outside of class
Why it works:
- Engaging Tutors: We make learning about sight, hearing and other senses simple and fun.
- Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
- Consistent High Quality: Unlike a live science tutor, these video lessons are thoroughly reviewed.
- Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about sight, hearing and other senses on the go!
- Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.
- Discover how the eye's cornea, lens, pupil and iris contribute to eyesight
- Learn about the functions of the rods, retina, fovea and cones of the eye
- Study the ways in which the optic nerve transmits information, and explore the functions of the eye's photoreceptors
- Examine the structures of the middle and external ear
- Learn about the correlation between the inner ear and balance
- Describe the contributions of the senses of taste, touch and smell
1. The Eye and Eyesight: Large Structures
The eyes are covered by several layers of protective tissues that help with the reflection of light and maintaining eyesight at different levels of light. Learn about the structure of the eyes, the description of the cornea, and how helps in maintaining eyesight.
2. Receptors of the Back of the Eye: Retina, Rods, Cones & Fovea
The receptors of the back of the eye enable humans to see the world in color and in detail. Study the retina, rods, the cones and fovea, and metaphors to help you remember what each photoreceptor is responsible for.
3. How Receptors of the Eye Conduct Information via the Optic Nerve
The receptors of the eye conduct information by catching light particles and converting the information into electrical signals that the brain can process into an image. Learn about photoreceptors, photopsin, rhodopsin, and the optic nerve.
4. Anatomy of the Ear's External Structures
The external part of your ear is what the sound waves reach first, so they have an important function in the hearing process. Discover how the hearing process works when you are talking to your friend on the phone and the role of the ear's external structures, including the pinna, the meatus (a.k.a. the ear canal), and the tympanic membrane.
5. Binocular Cues: Definition & Examples
By using binocular cues, the brain is able to create a three-dimensional image of an environment. Define binocular cues and discover its two variations: retinal disparity and binocular convergence.
6. Conduction Deafness: Definition & Causes
In this lesson, we will explore what the conducting system of your ears is and what structures are included in that system. We will also look at what some of the causes of conduction deafness are.
Earning College Credit
Did you know… We have over 220 college courses that prepare you to earn credit by exam that is accepted by over 1,500 colleges and universities. You can test out of the first two years of college and save thousands off your degree. Anyone can earn credit-by-exam regardless of age or education level.
