Heart Dissection

Kia Ora everyone! today I’m going to tell you what we did and how we did the heart dissection.

Equipment – Scalpel, Scissors, Tweezers.

1st thing we did was cut the heart in the soft part and open it up.

2nd thing We locate the four rooms of the heart which are the: Right Atrium, Left Atrium, Right Ventricle, Left Ventricle

3rd thing is to locate the remaining different parts of the heart.

Extra – 

Veins – Veins carry oxygen-depleted blood back to the heart from the rest of the body. They have thinner walls and lower pressure compared to arteries. Valves in the veins help prevent the backward flow of blood and assist in returning blood to the heart.

Arteries – Arteries are blood vessels that carry oxygen-rich blood away from the heart to the rest of the body. They have thick, muscular walls that help to maintain high pressure as blood is pumped from the heart. This allows the arteries to deliver blood to all the tissues and organs throughout the body.

Heart Valves – Heart valves are specialized structures in the heart that ensure blood flows in the correct direction. There are four valves: tricuspid, pulmonary, mitral, and aortic. They open and close with each heartbeat, allowing blood to flow through the heart’s chambers in the right order.

 

Doing this Dissection is really fun!

 

That is all for today

Thank you!

Chicken Leg Dissection

Kia Ora Everyone! Today I’m going to tell you my Aim, Method, and Results of the chicken leg dissection

Our aim for today is to dissect a Chicken leg and look at the tendons, muscles, and bones of the chicken using some scissors and tweezers

We do that by first removing the skin to see the muscles destroying the lower part of the drumstick and removing all muscles to look at the bones.

A chicken leg quarter with the meat removed, showing the femur, knee, tibia, and fibula

Discussion

The chicken leg tendons help connect muscle and bones together

The Femur of the chicken leg helped to hold the thigh meat

The knee joint is important because it is needed for any form of movement.

 

That is all for today

Thank you.

 

Effects of heat

Kia Ora everyone! today I am going to tell you the 4 experiments I’ve done in these past days.

Conduction (Dropping Pins)

Contraction (Imploding Can)

Convection (In Liquid)

Diffusion (In Liquid)

 

In Conduction, our goal is to watch the pins fall while the rod is heating up.

In Contraction, our goal is to watch the can implode.

In Convection, our goal is to watch the potassium spread to the water while the water is boiling

In Diffusion, our goal is to watch the potassium spread to the water.

 

I really like the Contraction experiment.

I like it because imploding can is one of my favorite things.

Here’s my write-up about it!

Our aim in the Contraction experiment is to watch the can implode

and I think that the can will implode, of course.

that’s all for today

thank you!
