Today at the lab, we tested two substances which represented urine samples for proteins and for reducing sugars. We decided to label one sample Mary and another sample John. These are the results we got:

Today, in our biology class we watched a presentation on nephritis and took notes about the topic. Here are my notes:

Last week at the lab we made a practical which consisted in testing the effects on 2 substances which we pew tended were urine samples to test them for glucose or proteins. These are the results we obtained:

Two weeks ago in the lab, we made a practical which considered on testing the effect of inspired and expired air on different things. This is the entry on the teacher’s blog (http://cadem.cumbresblogs.com/2019/10/21/testing-inspired-and-expired-air-in-the-lab/) and these are my results and analysis.

Blowing onto the thermometer:

The temperature rose from 25 degrees to 30 degrees. This was because of the heat our breath has.

Exhale onto the mirror

A kind of fog was formed in the mirror because of the heat our breath has that leads to the production of a sort of vapor when it gets into contact with an object such as a mirror.

Blow into limewater 

The test tube were the lime water was, was filled with a vapor due to the contrast between our breath and a cold surface such as glass.

Blow onto the glowing splint

Unluckily, in my group we didn’t get to blow into the wooden splint so we weren’t able to finish the practical. However I believe that if we had kept on blowing, we would have provided the fire with oxygen so at least a small flame would have been kept glowing.

Today in our biology class, we took notes on kidneys’ structure and functions. These are the notes I took along with Valentina Pease, Serena Braun and Mora Malenchini: https://docs.google.com/document/d/1I9v-axqDllfnp0hsxeOJ5rEV82l-T6TrUbBAm-mu5o0

Last Wednesday at the lab, the teacher brought to kidneys and we had to cut them in halves, take pictures and make a biological drawing. These are the pictures I took and the drawing I made:

In our last class at the lab, the teacher brought some small intestines in order for us to get a clearer idea of what they look like. These are the pictures we took:

Last Wednesday, in our biology class we began working with the end of chapter questions of chapter 9 in groups and the teacher told us we had to finish them by next Tuesday. This are the answers my group wrote:

Some weeks ago, at the lab, the teacher brought a cow’s heart for us to dissect. The first thing we did was cutting it open and spotting the coronary arteries, the pulmonary artery, the valves, the vena cava, the aorta, the pulmonary vein, the ventricles and the atria. Then, we were able to cut it through the septum without rupturing any tendon. Once we had the two halves, we analysed them in depth and made a biological drawing.

In our last Biology classes we have been working on ECGs. These are the notes I’ve taken on how they work:

ECGs

In our last class at the lab, we worked on a practica which consisted in watching our teeth with a mirror and then making a biological drawing of them. After that, some class mates used a mouthwash to check if they had any plaque. If they had plaque, their teeth would turn blue, if they didn’t nothing would happen.
