OMSI is here to help support your students' distance learning. We’ve expanded our Science at Home content to include new curated STEAM activities and resources each week!
Week 25: Eyes
Put things in perspective! Explore the science behind eyesight and make observations about how you see the world.
Monday: Science Reading
Cameras and The Eye
Cameras and the human eye have a lot in common! Our eyes use a cornea, lens, iris, and retina to collect and direct light. Photoreceptor cells then turn light into electrical signals, which are sent via optic nerves to the brain where an image is perceived. Similarly, cameras have an opening for light, a lens to refract the light, as well as a surface where an image is formed.
- How are cameras similar to the human eye?
- How are cameras different than the human eye?
- Which is better, the camera or the eye? Why do you think so?
Tuesday: DIY Activity
Find Your Blind Spot
Can you find your blind spot? The retina in your eye senses light and transmits visual signals to the brain through the optic nerve. Your blind spot is the one area on your retina where the optic nerve connects—and where your retina cannot sense light or see!
Wednesday: Career Connection
Becoming an Ophthalmologist
An ophthalmologist is a medical doctor who specializes in the eye and vision care. Ophthalmologists differ from optometrists and opticians in their level of training, as well as in what they can diagnose and treat. Learn more about becoming an ophthalmologist in this video.
Questions to think about:
- How do ophthalmologists help keep human eyes healthy?
- What procedures might an ophthalmologist perform?
- What science topics would be important to study before becoming an ophthalmologist?
Thursday: Observation Journaling
Humans are capable of seeing certain distances and colors, as well as in different amounts of light and at certain angles. The vision abilities of animals can differ significantly, making their visual perspective of Earth very different from our own.
Today, make observations about how you see the world compared to other beings.
- Grab paper and something to write with.
- Find an environment where you can sit comfortably.
- Draw the space based on how you see it.
- Next, draw the same space through the eyes of another, for example:
- A dog that cannot see color
- A horse that sees with monocular vision
- A fly that has several lenses on its eyes
- A bird that is seeing the space from above
Get a greater understanding of the ways animals see the world and explore how dogs, geckos, and see things differently from humans.
Questions to think about:
- Did your perception of the world change after "seeing" it from the perspective of another animal?
- What similarities and differences do you notice between the drawings you made?
- What would you change about your eyesight?
Friday: Design Challenge
Designing Ideal Eyesight
Each animal, including humans, has eyes that suit their needs. Predators, for example, usually have eyes facing forward instead of on each side of their heads.
Your challenge this week is to design ideal eyesight for each imaginary animal described below. Draw each animal's eyes and write or tell someone a description of what you designed.
- An animal that flies and primarily eats fish
- An animal that eats plants and travels in herds
- A marine animal that lives at the bottom of the ocean
When designing eyesight for each animal, remember to consider these questions:
- Where are its eyes located on its head?
- Can it see color? If so, what colors?
- Can it see in the dark? Why or why not?
- How will its eyesight help it find food?
- Why did you select certain eye characteristic for certain animals?
- How have eyes evolved to suit certain types of animals?
- What would you add to human eyes to make them more ideal for us, especially in a world dominated by screens?
