This week for Genomics we are learning about Zebrafish.
First we watched a video, filled in the missing words from the transcript of the video, defined new words and answered questions.
Next the group who were online that day (Kymani, Davlyn, Eh Htoo Wah, Wesley, Railey) created this profile of a Zebrafish.

New words: .
Anatomy- study of the body.
Post-fertilization - after the boy part and girl part come together to make a baby (when the cells combine)
Himalayas - mountain range that separates China and India
Embryo - a group of cells that turn into a baby or egg
Genetic - relating to your DNA
Himalayas - A country that has a lot of Mountains
Ganges - a long river in India
Organs - body parts
Juvenile - child/teenager
Sections - slices
Stained with dyes - putting different coloured liquids onto it so you can see different parts
Coronal - cutting in half vertically E.g. separating the front and the back
Transverse - cutting in half horizontally, E.g. cutting the head off the body
Sagittal - cutting in half vertically - E.g. cutting the left side away from the right side.
Main ideas in our own words:
Mariah - Zebrafish live in the river in india.And zebrafish are transparent and they have fresh water.And scientists study about zebrafish.Zebrafish is 2.5cm to 4cm long. And It takes 2 to 3 days for the egg to hatch and it’s lifespan is 2 to 7 years.
Coronal - cutting in half vertically E.g. separating the front and the back
Transverse - cutting in half horizontally, E.g. cutting the head off the body
Sagittal - cutting in half vertically - E.g. cutting the left side away from the right side.
Hope - Zebrafish is transparent and they live in Ganges river in the wild, in India where they have fresh water. Scientists study the zebrafish because they are transparent so the scientists see inside it. Zebrafish is 2.5cm to 4cm long, Embryo is the egg of the zebrafish and has three layers which are single cell,yolk and chorion. After the scientists breed about a hundred or thousands of zebrafish they kill them and look at them under a microscope to study them. It takes 2 to 3 days for an egg to hatch, the zebrafish lifespan is 2 to 7 years.
These are different kinds of cuts.
Coronal - cutting in half vertically E.g. separating the front and the back
Transverse - cutting in half horizontally, E.g. cutting the head off the body
Sagittal - cutting in half vertically - E.g. cutting the left side away from the right side.
Scientists kill the zebrafish at different ages(hour/days post fertilization). Scientists take photos of the different stages of how the organs grow. They use different kinds of dye to see different kinds of body parts and they take pictures of it to see the difference between zebrafish.
This is a 48 year old coronal, the big round part is going to This is a 48 transverse and the two big Be the body part circles are going to be the eyes
Zebrafish has three layers in its egg: the single cell,the yolk and the chorion. They live in India inside the Ganges river in the southern himalayas. Scientists kill the zebrafish with chemicals then cut them in 3 ways Coronal,Transverse and Sagittal. Scientists kill them in different ages (hours post fertilization).
Michael - Zebrafish live in a river in india. And zebrafish are transparent. They live in India where there is freshwater. Scientists study zebrafish because they are transparent. Zebrafish is 2.5cm to 4cm long. In its larval stages it is transparent and as it matures to an adult it develops stripes that run along the length of the
body and look blue in colour. The zebrafish are called embryos; the egg has three layers: The single cell. The yolk and the protective membrane. And it takes 3 or 4 days for the egg to hatch and the zebrafish lifespan is 2 to 7 years. After scientists breed about a hundred or thousands of zebrafishes killed them and looked at them under a microscope to study them. E.g cutting the head off the body, sagittal means cutting in half and vertically E.g cutting the left side away from the right side. Different types of dye to see different body parts like
the eyes then the scientist do pictures
Davlyn - The zebrafish lives in india rivers. Scientists like studying zebrafish because they don’t take that long to hatch or take long to grow up but with humans we take long to grow up, they also like to study them because the zebrafish are transparent so the scientist see inside it. The zebrafish eggs are called embryos; the egg has three layers: the single cell, the yolk and the protective membrane. It takes 2 to 3 days for the egg to hatch and it’s lifespan is 2 to 7 years. To see the inside of the zebrafish they cut the fish to see what is inside of the zebrafish, they cut the zebrafish in 3 different ways, Coronal means cutting in half vertically E.g. separating the front and the back, Transverse means cutting in half horizontally E.g. cutting the head off the body, Sagittal means cutting in half and vertically E.g. cutting the left side away from the right side. Different types of dye to see different body parts like the eyes then the scientists takes pictures.
This is a 3 day old fish, cut in the coronal way. The top part looks like it is the brain and the bottom looks like that is going to be the tail.
this a three day old transverse cut zebrafish. The center part will become the brain the and the two holes on the side will become the eyes.
Railey - zebrafish lives in a river in india, and they were known to be transparent/see through, and scientist study them because zebrafish don't take long grow and because they see through the egg so they didn't have to use xray and it only takes 2 to 3 days to grow or hatch an egg and they can survive for about 2 to 7 years depending of where they are. Scientist cuts them in different way to see or learn about them
These are the kind of cuts:
Coronal - cutting in half vertically E.g. separating the front and the back
Transverse - cutting in half horizontally, E.g. cutting the head off the body
Sagittal - cutting in half vertically - E.g. cutting the left side away from the right side.
Scientists also cut them in different ages(hour/days post fertilization) and take pictures or use dye of what they look like when they grow up and how long they are or see their body part like eyes and body.
this is picture shows how a zebrafish looks when its a 3 day old fish cut in coronal way.
this is zebrafish cut in a traverse it has a length of 3.5mm
Eh Htoo - we are learning about zebrafish. They are transparent and live in India's Freshwater lakes or rivers. Scientists study them because they are transparent and reproduce fast, scientists breed hundreds and thousands of zebrafish to study them.Then Scientists kill the fish in chemicals and cut it up. If they cut it in different shapes like coronal, cutting in half vertically, separating the front and the back, transverse cutting in half horizontally, cutting the head off the body Sagittal cutting in half vertically, cutting the left side away from the right side. When they cut it it will show different parts.Scientists kill way too much of the zebrafish.
These fishes are a year old and and they are cut Transverse you can see a lot of meat.
EXAMPLE
This is a 48 hour old fish, cut in the coronal way. The two big purple circles will become its eyeballs. The big red circle on the right will become its body.
This is a 12 month old fish. You can see its organs on the inside of its torso. It is fully developed with a long tail. It is cut in the coronal way.
