  1. Haylee Peace & Devan Neal Period 3 The Life of Sophia

  2. Hello Sophia! Hi, my name is Sophia Cambell, and I am the famous Japanese Medaka egg. I come from a small island in the Pacific Ocean. Somehow, I wound up being observed and studied by Mrs. Wolfgang’s biology students. I’ve gone through a long journey, all the way from a tiny embryo until I finally hatched.

  3. Day one On the first day that I arrived at Punxsutawney High School, I was a young forty hours. At this time, I would have been at stage 22 in my hatching process. During this stage some features the students noticed about me were my oil globules, filament and cytoplasm.

  4. My Noticeable Features

  5. Words to Know • Oil Globule- A food source for the developing embryo, also helps pump blood through the embryo • Filament- A fine continuous strand of cells, that look like little hairs on the outside of the egg. • Cytoplasm- The cytoplasm is a storage place for chemical substances indispensable to life, it helps maintain the shape and consistency of the cell, and also provides suspension to the organelles.

  6. Day 3 • The third day that I was being observed I was at stage 23. At this point I began to develop a heart beat that was visible to my observers. When they tested my heart beat, they found that it was racing at 109 beats per minute. When observing through the microscope Haylee and Devan could still see my filament, as well as my chorion.

  7. Features

  8. Features

  9. Words to Know • Chorion- a membrane that provides nourishment to the embryo by surrounding the amnion and attaching to the uterine lining. • Heart- pumps blood through the embryo.

  10. Day Four • Haylee and Devan continue to take care of me. Today they put me under the microscope and took pictures of me. They change my water every day to ensure my safety. At this point in the process, I’m at stage 25. You can see my brain and optic cups, and my oil globule is still noticeable.

  11. My Features

  12. Words to Know • Brain- controls functions related to hormones, breathing, and salt consumption. • Optic Cups- bi-walled cup-looking indentation, formed by invagination of the optic vessel. It develops into the sensory layers of the retina.

  13. Free at last! • Day six rolled around and I was ecstatic to finally emerge from the small confinement of my cell. Once I was free I flew around the water like a missile! I was going so fast that Haylee couldn’t even take a picture of me! When she tried, my mouth was out of the picture.

  14. My Features

  15. Words to Know • Dorsal Fin- helps to stabilize the Medaka. • Yolk Sac-a membrane sac attached to the embryo that provides an early nourishment in the form of yolk. • Somites- Little dots you see on the tail that define the segmental pattern of the embryo. • Pectoral Fin- Helps the fish to steer and stop.

  16. Reaching the end! • I’ve had an amazing journey with Haylee and Devan, and they learned a lot through studying my embryology. I showed them the changes from stage to stage and that allowed them to relate it to human embryology. The enjoyed their time spent with me!

  17. Requirements for Survival • Before Hatching: • Haylee and Devan kept me in a container of spring water, they had to be sure and change the water everyday so I wouldn’t get sick or die. I am very small and easy to lose, so they used a pipet to take me from one container to another as the water was being changed. Because of my small size, they had to use a microscope to see how I changed from day to day. To help them monitor my changes they used a motic cam to take pictures.

  18. Requirements for Survival • After Hatching • After I had hatched I was put into a bigger bowl in Mrs. Wolfgang’s room. This bowl had a filter, so cleaning my water daily wasn’t necessary but it should still be cleaned every so often. I was also fed very small amounts about two to three times a day.
