Chicken Leg Dissection// Science//10Hh

Chicken Leg Dissection

Aim:    In this Dissection, I will locate and describe the various tissues and structure of the drumstick and thigh of Chicken.

Equipment:       Chicken drum with the thigh

              Dissecting probe

              Scalpel

              Dissecting scissors 

              Paper towels

              Dissecting tray

              Gloves

              Disinfectant hand wash and spray

Method:          

1. Place the chicken leg on a Dissecting tray and examine the exterior features. The tough outer layer is called the epidermis (Skin). The small bumps covering the skin is where the feathers were attached
2. Examine the lower leg. This is called the drumstick and it is the equivalent (same as) of your lower leg. The large muscle at the back of the leg is the same as your gastrocnemius. It also includes two bones- the tibia (large one) and the Fibula (the smaller/thinner one.
3. Examine the upper leg. On both the chicken leg and human, They both have a thing called the thigh this is called the femur
4. Carefully pull the skin off by sliding it down and off the lower leg. You may need to use the scalpel to remove it. But be careful not to cut any muscle tissue.
5. The muscles of the leg, like all muscles, work in bundles. Separate a bundle of muscle by inserting your thumb into the muscle of the lower leg. you'll notice that the muscle bundle is covered in a shiny lining called the fascia and this makes it hard to separate but if you push hard enough you will tear ut find that separating muscle bundles is a lot easier.
6. At either end of the muscle, you will see white cord-like tissue. These cards are called tendons. Tendons attached to the bone.
7. Using the scalpel, carefully remove all the muscles from the lower leg. using your dissection probe to examine any blood vessels you find and try to determine which muscles the blood is supplied to.
8. Near the bone, you should see thin, thread-like strands. these are the nerves
9. Using the dissection scissors, cut across the tendons that join the muscles to the bones. Be careful not to cut any ligaments that attach bone to bone. You should end up with all the bones still attached to each other, but no muscle tissue present.
10. Move the bones around the joints, The main joint between the bones of the lower leg and the femur is a hinge joint like the one in your knee. Not how the bones can move only in one plane.
11. Using your scalpel, carefully cut the ligaments, keeping the bones together.
12. In the joint between, the nones is a piece of cartilage. Cartilage allows joints to move smoothly and protects the bones against shocks to the body.
13. Break one bone in half and examine the marrow. This is where blood cells are made
14. Clean up your work area. Ensure you clean your bench using antibacterial spray. Wash your hands thoroughly with plenty of antibacterial soap and water,

Results:          

My observations from this experiment is that... The Chicken smells like a rubbish bin, but things I could see was each tendon and I ended up removing some, I could see and feel the muscles. The muscles feel like a more frim like an overcooked piece of steak. The tendons are not what I expected they feel like a very thin noodle type silicone. trough out this experiment I learnt how to understand the human leg skeletal muscle system by comparing it to the chicken. I saw how the joints work and why cartilage is needed, I saw tendons and ligaments and can now point them out on the human body 

   

Here are some photos Iong the way.

Micheal Mew// Art// 2019

Over the past few weeks we have been making Micheal mew Art pieces, For this, we have had to use different shapes colour textures. We have also had to make sure we had vocal points and leading lines. For my work, I used watercolours as well as pieces of work I cut out of the magazine and my focal point was the Mohua

methamphetamine

Meth use can cause irreversible harm this includes, Increased heart rate and blood pressure, Damaged blood vessels in the brain that can cause strokes or an irregular heartbeat, liver, kidney and lung damage this can cause collapsing or even death. This will really mess up your physical well being because you are gonna end up so reliant on the drug and become addicted. Things you can do to help someone who is struggling with being addicted to this drug is:Cognitive behavioral therapy.Contingency management.Family education.12-step support programs.

Breakfast muffins// Home ec

Last week we cooked Breakfast muffins, these where really yum we did end up changing around some of the ingredients but here is the updated recipe.

Ingredients 

1/2 Tbsp olive oil 

1/2 onion diced

4 slices ham

4 cherry tomatoes

1 1/2 cups self-raising flour

1 Tbsp parsley chopped/ diced

1/2 tasty cheese

1/2 smoked paprika

2 eggs

to taste sea salt and cracked black pepper

1/2 cup milk

Directions

1. preheat oven to 185c on fan bake.
2. line 8 large muffin holes (or a regular 12 tray) with baking paper squares large enough to come up the sides. (We used a canola oil spray)
3. heat the oil in a frying pan and saute onions for 3-4 mins until the onion is soft. Set aside to cool.
4. in a large bowl, combine the tomatoes, parsley, flour, cheese, paprika and season.
5. add the cooked onions and ham and stir to combine.
6. whisk together eggs and milk and fold into other ingredients gently until just combined.
7. spoon into prepared trays and bake for 12-15 mins until golden and puffed.

Things I will next time definitely add more ham and cheese and less parsley,
Things I learned, I learned how to saute properly and now I can do that easier next

Slave trade// Social Studies// 10Hh

Over the past week in Social Studies we have been working on the slave trade triangles, This is actually so upsetting to see how people were treated back in  days.
Here is my 'My Map' this is a diagram of where the Europeans sail to drop off the slaves.

Chocolate double helix// science// 10Hh

Double Helix made out of Chocolate.
A pair of parallel helices intertwined about a common axis, especially that in the structure of the DNA molecule (but instead this one is made out of chocolate)

Aim- To make a successful Double Helix made from chocolate
Equipment- One block of chocolate, Bowl, baking paper, piping bag, microwave, freezer, Spoon.


Method: 

1. Place all the Chocolate into the bowl
2. Put in the microwave for 30 take out an repeat if needed
3. When it's done lay down a flat piece of baking paper
4. Open the piping paper and spoon all the chocolate into it then cut a small hole at the tip
5. draw one wiggly line then another identical but mirrored then draw a line connecting the to sides of the helix together
6. place in the freezer

Observations

While making this double helix it was quite difficult because it was hard to make both sides of the helix's identical, but I tried to do the best as I could!!

Conclusion

Well obliviously it wasn't a real double helix but considering that it was made out of chocolate I think it looks pretty good, Next time I would definitely have focused more on the detail and maybe used different kinds of chocolate and maybe coloured some.

Discussion
Deoxyribonucleic acid (DNA) is the same in all living things. It looks like a twisted ladder known as a Double Helix. DNA is made up of continuous units called Nucleotides. A Nucleotide is made up of sugar and phosphate also a base. Both sides made up of the Sugar and phosphate are joined together by chemicals called Nucleotide bases.

Evaluation
A couple of things that would make it easier on you is...

• Place the chocolate into the piping bag before melting then melt it in the piping bag.
• Draw a couple of different diagrams so you have options.

Next steps

Things I could have done better/change...

• I would have definitely paid more attention to the details.
• I would use different colours and flavors so that it would look a lot better.

I think that could have done better if I did both of thing but I'm still proud that it has the same outline as the double helix.
