Heart dissection - Science

Aim:
To dissect and identify the parts of a heart.

Equipment:
Newspaper
Heart
Scalpel
Scissors

Method:
1. Spread out the newspaper 3 layers thick.
2. Identify the right atrium and the left atrium.
3. Stick your finger through the pulmonary artery into the right ventricle.
4. Stick your finger through the Aorta into the left ventricle.
5. Cut open both the left and right sides of the heart so you can see the left and right atrium, and then the left and right ventricles.



Results:
When I first touched the heart it felt very muscular and when I put my finger in the Aorta it felt quite slimy and wet. The smell of it was just disgusting. This was the first time I've ever dissected a lambs heart or even seen one but I think it was a good experience and that the dissection went quite well. I was able to identify quite a few parts of the heart like the Aorta, left and right ventricles and the septum. What I found out was that the left side was thicker than the right because it carries blood to the whole body whereas the right side only carries it to the lungs.

Rice and Chicken Patties - Home Ec

Friday 17th Feb



Our procedure of making rice and chicken patties.
Before we started we tied up our hair, put on aprons, took off jewelry and made sure our hands were clean and ready to cook and handle food.
Our health and safety rules applied to this recipe when we had to make sure our chicken was cooked properly, making sure we used the correct boards and knives so nothing cross contaminated and made sure that everything was clean before we used it.
A personal highlight from this cooking session was

Measuring Grip Strength - Science

Aim:

To measure grip strength with different positions.

Method:

First we made the device that measured our grip strength. We used popsicle sticks, a bulldog clip, blu tack, glue and a print out of a protractor.

We measured out grip strengths by pinching the bulldog clip with our thumb and index finger then a friend would look at the protractor and see what degrees it was on.

Results:

My results were 30 degrees pointing down, 30 degrees on neutral and then 15 degrees pointing up.

The main result of the graph is that the neutral position is the strongest.

Health and Safety - Home Ec

For the first few periods we have been looking at health and safety and hygiene. We have also learnt about bacteria, you can only leave out food for about 2 hours before the bacteria starts to grow. And also about cross contamination.

Health and safety is important in the classroom because there are a lot of hazards the could harm us. We need to keep ourselves and our food safe.

The routines we have put in place are just the basic things like washing hands, having hair up, aprons, wiping down the tables, etc.

Bacteria can't grow without a few things such as; Warmth, moisture, oxygen and food.

Building Sport Specific Muscles - Science

In Football/ Soccer it is really important to have strong leg muscles. So I am going to design a training program that will work out some important leg muscles, the Quadriceps and Hamstring.

Muscles work in pairs to move your body parts, they do this by contracting and relaxing. Muscles are connected to your bones by tendons, they’re attached so well that when you contract a muscle your bone and tendon will move along with it.

I would suggest these workouts to strengthen the legs..

• Squats.
• Step ups
• Lunges

When we use our muscles it causes them to strengthen. This training program focuses on squats, lunges and step ups. All of those focus on working out the muscles in the leg which will make them stronger for playing soccer.
