DNA Extraction Experiment

 Aim: Extracting DNA from a kiwi fruit

Method: 

  1. Mush half a kiwi fruit in a zip lock bag with a splash of water and add a small teaspoon of salt

  2. Strain the solution through the cloth into a beaker 

  3. Add a squirt of dishwashing liquid and stir. 

  4. Pour into a test tube

  5. Place the test tube in a beaker filled with WARM water

  6. Leave for ten minutes 

  7. Slowly pour 5mL of methylated spirits on the side of the test tube.

Results:

 

Discussion: Where do you find DNA?

DNA is located in a cell called the nucleus

What makes up DNA?

DNA is made of chemical building blocks called nucleotides

Conclusion:

The experiment did work we got to see the DNA separate from the mushed kiwi fruit and I wouldn't change anything from the experiment

Making a metal oxide - science

 Metals and oxygen

Aim: To make a metal oxide and observe the difference in properties of the products compared to the reactants.

Equipment:

  • A piece of magnesium

  • Bunsen burner 

  • Safety glasses 

  • Metal scissor tongs 

Method:

  1. Light your bunsen burner. 

  2. Hold your piece of magnesium in the scissor tongs. Ensure you are holding onto the very tip of the magnesium. 

  3. Place the other end of the magnesium into the Bunsen flame (at the top of the blue fame)

  4. When magnesium begins to burn, do not look directly at it, as the light emitted can permanently damage your eyes. 

Observation: The magnesium lit up and sparked up for a while and then dimed out 

Discussion: Magnesium + Oxygen → Magnesium Oxide, Using the scissor tongs and the magnesium metal being held over the blue flame made the magnesium light up and burn for a few seconds. 

Conclusion: This experiment went very well and I learned that magnesium lights up when being burnt, I would not change anything during this experiment. 



H pop - Science

Testing for hydrogen gas

Aim: To show that hydrogen gas is produced when a metal reacts with acid.

Equipment: 

  • Test tube 

  • lighter

  • A boiling tube 

  • Wooden splint

  • A bottle of acid

  • A piece of metal

  • Safety glasses 

Method: 

  1. Add a sample of metal to your test tube. Add 2 ml of acid. 

  2. Carefully invert your boiling test tube above the test tube containing the metal and acid 

  3. Hold the test tubes together for a few minutes, allowing time for the inverted boiling tube to full with gas 

  4. When you think the test tube is full (wait a minute) your partner should light a wooden stick 

  5. Carefully but quickly tilt the boiling tube full of gas upwards and insert the burning splint into the mouth of the test tube.

Results: it made a popping noise 

Discussion: The reactants began to bubble and smoke 

Conclusion: The experiment was successful and popped as it should have and what I would change is nothing.

Model atom - Science

 Model atom

Aim: To make a model atom

Method:

  1. Choose an atom to make (one between hydrogen and neon)

  2. Work out how many protons, neutrons, and electrons 

  3. Assign protons and neutrons to a particular colour bead.

  4. Get a ball of blue tac and stick the protons and neutrons to this to make your nucleus.

  5. Cut the appropriate electron shells and draw in the electrons with vivid.

  6. Connect the nucleus and electron shells with a piece of string 

  7. Create a label to go above the model so people know what you have created.

Results -

For the model of the atom, I chose to do carbon 

 

Discussion - 

The atomic number for carbon is 6 and the mass number is 12. There are a number of 6 protons,6 electrons, and 6 neutrons.

2 facts about carbon - 

  • Carbon gets its name from the Latin word carbo, which means "coal."

  • Carbon occurs naturally as carbon-12, which makes up almost 99 percent of the carbon in the universe

Conclusion - 

Yes it did work and I wouldn't have changed anything

Health blog post

 In Health we were set a task that required us to research and provide information about something that is around health. The topic I chose to do was alcoholism. 

The first thing we did was to find a topic that we were interested in researching, once we finished choosing your topic we had 5 big questions to ask and answer. 

Here are my 5 big questions, I chose these questions because I think that they are the most important questions to be asked. 


Why do people become alcoholics?

There are many reasons why people become alcoholics. It could be from a mental illness or psychological problems such as low self-esteem, high stress, or depression, or maybe it could be passed down in the family. It could have been passed down from either the father or mother's side or even both.


What is alcoholism?

Alcoholism is an alcohol use disorder. It is when one can no longer control their use or intake of alcohol and experience emotional distress when they are not drinking.


Who is disadvantaged and advantaged in relation to gender and sexuality around alcoholism? 

Even though there are different patterns of alcohol usage around the globe, males are more likely than women to be heavy drinkers or alcoholics. Men may use drinking as a way to facilitate anger, export power, or to take risks. Women are more likely to stop drinking. That may be related to generally lower levels of drinking, social roles, or does not want to resume drinking.


How does alcoholism affect the brain when intoxicated?

Alcohol Heavy drinking has an effect on the complex structures of the brain. It blocks the chemical signals between brain cells. Leading to common symptoms of being intoxicated. Examples blurred vision, impulsive behavior, slow reaction times, difficulty walking, slurred speech, and poor memory


What are the consequences for long term and short term alcoholism?

Drinking too much overtime can cause many physical and mental health illnesses. A long term effect of alcohol abuse puts you at risk of liver disease, pancreatic, heart disease, inflammation in the stomach, and some cancers, it can affect your immune system or catch more colds and illnesses more than usual more than others who don’t drink.


From there we came up with 3 strategies that will help prevent or deal with the topic we chose. These strategies are helpful to use if you are ever going through something like this topic. 


Find alternatives - 

Taha hinengaro and Taha whanau. Finding alternatives will improve on your mental health by finding ways to decrease the amount of drinking you do. Activities such as exercise, music, and getting a massage can provide opportunities to hang out with friends or plan a date without going to a bar or club. If you rely on alcohol to wind down at home, effective stress relief alternatives can include meditation and gratitude journaling. Finally, there are many delicious alternatives to alcoholic drinks for sober or sober curious.


Set goals- All 3 dimensions. When people successfully change their habits they usually follow a simple plan and choose a goal. 

For example 

  • When bored or stressed workout instead of drinking 

  • Avoid drinking in large groups

  • When out with friends avoid getting alcohol 


The first decision is to decide what you wish to achieve by changing your drinking, there are a number of choices you can make depending on your current drinking pattern. The following guide may help you in your decision but only you can make the decision that is right for you.

Get support - Taha hinengaro. Although a few people have too much pride in themselves to want support, support could be something like a support group for alcoholics, support could also be asking your family members or close friends around you for help. Getting support can improve your taha hinengaro in many ways, It can decrease the number of mental illnesses you have, it can help make new and better connections with others, and to see how others may have gone through it and what their outcome was. 

Taha tinana. Getting support will improve your taha tinana by decreasing the amount of alcohol you put inside your system. It also can help decrease the physical illnesses the body may have gained by drinking too much alcohol.


We then chose to make/create something that relates to the chosen topic, we did this to teach others about our topic/findings. 


Here is a photo of my collage and of me painting my artwork. 

This discovery task was challenging because you had to make sure you understood the topic and the findings of the research, the way I coped with the challenge was to choose a topic that I understood, and that made a lot of pressure go away. I am proud of myself for working independently and for doing two create tasks. I think I worked well independently because if I were in a pear I would also have to depend on the other person in my group to contribute to the work.


This is the link I got my photos from.

Dissecting the hearts - Science

The experience dissecting the hearts:

In science today we dissected a heart. We used tools like tongs, scissors, and a scalpel.

1. What have we been learning about?
We've been learning how about the heart and the circulatory system and how it works 

2. Why are we dissecting a heart?
We dissected the heart to see all the parts and how it all attaches together. since most of the diagram are all different we wanted to see for ourselves

3. What are the parts of the heart? Did you see them?
while we were dissecting we saw parts of the heart such as the valve, some of the arteries, and the septum. We also felt how the left side thicker than the right.

4. Did you enjoy the dissection? Why/why not?
It was alright, it did smell bad but other than that it was good.
