MICROSCOPE BLOOD SAMPLES!

The other day I got to look through a microscope at blood samples. I tried 4 different samples; Sickle Cell, Smear, Kambio and Sperm. These were amazing to look at... but sperm was by far the best! Looking through the microscope made it look like purple and pink bunched up jelly beans!
I had so much fun, and microscopes are AMAZING!

Lowest Common Multiple & Highest Common Factor

Today we looked at the Lowest Common Multiple and Highest Common Factor

Check out this clip from class this week. It's a Sheep's pluck with air being pumped into its lungs.

Pluck

A few days ago me and my class had a look at some of the organs of a lamb. We looked at the liver,the lungs, the heart, the windpipe and the tongue was even there! We got to get a good look and feel of arteries and what organs feel like. The teacher showed us the sectum and pumped air into the lungs, it was good watching them inflate.

The other day we had the opportunity of dissecting a heart. This was a very interesting activity and I enjoyed learning all different parts that make up the heart. The key points we looked at was the trachea, veins and arteries. I learnt that the veins job is to transport blood to the heart, whereas the arteries transport blood away from it to the lungs. I also learnt how to find out the difference between the left and the right side of the heart. The left side's wall would be a lot more firmer than the right. I really wish we could do this activity again sometime.

In science today we got to dissect a heart, which was like the pluck that we did earlier
this weak, but it was even better. Luckily I got to be the one that made the incisions,
which made the experience even better than it already was. MVW took pictures and
taped it, so that was good too. The heart that we got was monstrously huge, and the wall
of the left ventricle was atleast 1 inch thick. Nearly all of the features were clearly visible,
but the valves were less obvious than they were in the text book. We didn't have any
problems, and everything was fun, even putting the scalpel together.

This has definitely been the best activity we have done in school, and I think lab pracs are
going to be one of the most fun things we do all year.

Yesterday we dissected a sheep's heart. It was really interesting and I would never have done that at my old school. We got to observe the key points that makes a heart function, including the trachea, veins and arteries. Sounds really gross but is actually really cool and I am really excited about what we will learn this year.

Today we did a heart dissection and we could see everything that we learnt in class

a few weeks ago .We got to feel the sheeps heart and we got to cut it open. On the

right side of the heart me and my friend could see some of the deoxygenated blood

that was still left inside the heart. And of the left side their wasn't much oxygenated

blood but the left side of the heart was really tough unlike the right side of the heart

which was soft. In previous lesssons jp7numeracy told us that the left side of the heart

is stronger then the right side of the heart becuase the right side of the heart has to pump

blood all around the body.

Pluck, Heart and More


In the past week our class has been doing some biology in the class. we started off with the pluck, were we got to have a look at the main organs of a lamb, including the Trachea, Lungs, Heart and the Liver.

2 days after we then got to dissect a sheep heart with my lab partner MN it was awesome!!!!! We had one cut each and then used the tweezers to poke through the main arteries and veins.

i cant wait till my next science lesson!!!!!!!!!!

Yesterday, I had the interesting experience of dissecting a sheep brain, I was scared cutting open the brain, so thats why I was a scribe. I documented the whole dissection! But that wasnt my only job, my second job was to examin the brain and all the parts including the aorta, right ventrical, left ventrical, pulmonary artery, pulmonary vein etc!!!

The Pluck.

Not to long ago, I undertook the challenge of touching the inner of a sheep! (the lungs, heart, trachea and liver)
I had to feel the lungs and other parts and observe things. I found out that the lungs expand majorly when we breathe in and out! The pluck was enjoyable and i had lots of fun!
Now I know more about the human body! (and a sheep's)

Today during class we had the heart dissection, this was very enjoyable. we learnt about where the veins are and that the walls of the left and right are very different. Shown on the left is the left wall of the heart, it is much thicker so it can deal with the pressure of pushing blood around the body.

Today we did a Heart Dissection. It Rocked!!!

In Term 1 this year we will be looking at Whole Numbers, Operations, Number Properties and Patterns, Fractions, Decimals and Percentages in Maths. In Science we will be looking at Body Systems, Circulatory System, Digestive System and Reproduction.

Some awesome pracs and learning coming up. Stay tuned!
