Healthy Living for Teenagers

 HEALTHY EATING

Eating healthy food is one of the most important factors to living a long and healthy life, eating healthy food improves your energy levels, and even mood. Food charts recomend you eat lots of vegetables and meats containg high amounts of protein and vitamins while cutting out most of the sugary foods.

SLEEP

The recomended amount amout sleep you should get every night is between 8-10 hours, however some people are able to get slightly less sleep then recomended without being tired. Sleep is healthy for you because it rests your mind allowing for it to regenerate energy for the next day and clear out all the 'clutter' or unnecessary information.

EXERCISE

Exercise is great for your body and your mind, physicaly it helps your blood circulate better, lowers the risk of heart and circulatory disseases and for people with type 2 diabetes, it helps your body use the insulin you have left. Mentaly, exercise can help clear your mind from bad thoughts while improving your memory and attention span at the same time.

Red Cabbage Indicator experiment

Materials

1. Red Cabbage

2. Beaker

3. Bunsen Burner

4. Pipette

5. Sodium Hydroxide

6. Hydrochloric acid

7. Test Tubes ( x5)

8. Paper towel

9. Test tube rack

10. Water

Steps

1. Chop up the red cabbage into small pieces. Place in a beaker and cover with a small amount of water.

2. Bring the solution to the boil using a bunsen burner and then turn off the heat. Let it sit to cool down.

3. Pour the cabbage water through a paper towel into a beaker. The dark purple liquid in the jar is the pH indicator liquid.

4. Suck up the indicator into a pipette.

5. In a test tube, use the cabbage indicator and the pH chart below to test the acidity of the the hydrochloric acid and ammonium hydroxide.

Findings.

What is the pH of liquids.

1. Sodium Hydroxide - 11-12

2. Hydrochloric acid - 2-3

At Hornby high before the first day you have a short period of time (between 1-2 hours) where you get to meet your form/wananga teacher. "Whats a wananga teacher?" you might be asking, well, a wananga teacher is the teacher you spend 7 hours a week with doing things about wellbeing.

What about the other 5 hours of the day? We have different teachers doing either  hurumanu or other activities (P.E, Japenese, Maori, woodtech, etc).  Hurumanu classes are your normal run of the mill subjects (Literacy, maths, etc)

Hornby high can be fun with the many opportunities people get in school, things like Cantamath (A math competetion I recently participated in), Air velocity (A car race where you build the car you race in), Epro8 (A engenering competition).

Facts about chili

Explains SHU

Food Theory 'Beat the Heat'

5 Facts about chilli

1. The scovile heat unit scale (SHU) was invented in 1912 by pharacist Wilbur scovile in an attempt to find a heat producing ointment.

2.The burning sensation is mainly caused by the chemical capsaicin. Capsaicin is found in tiny glands in the chilis placenta, when you eat a chili the capsaisin is released into your saliva and then binds to TRPC1 recepotors in out mouth and tounge.

3.Chillis are considered a fruit, they are consideered a fruit because they are a member of the nightshade (Solanaceac) family and they are related to tomatos, cherrys and eggplants.

4.Some chillis are used in different medical things like nasel spray and dermal patches.

5.Only mammals are sensitive to the chemical capsaicin making it so fish arnt effected by chilli peppers.

Hypothisis

I think by drinking milk it will remove the heat because it has a chemical in it that binds to capsasin reducing the heat.

Method

Equipment

• Hot Chilli sauce
• popsicle stick/tooth pick
• Drinks- soda, water, milk
• Timer

Instructions

1. Get your equipment ready
2. get a drop of hot sauce on your toothpick/popsicle stick
3. lick the hot chilli sauce
4. start the timer
5. after 2 mins, drink your drink
6. after 5 mins, how hot is your mouth
7. repeat the experiment but with a different drink

Results

How hot was the chilli after 2 mins

5/10 (water) (Tane)

7/10 (coke) (Tane)

3/10 (milk) ( Me)

how hot was the chilli after you drank your liquid (Coke, Milk or water)

2/10(water) (Tane)

4/10(coke) (Tane)

0/10(milk)(Me)

How hot was it after another 3 mins (after you drank your liquid)

2/10 (water)(Tane)

 2/10(Coke)(Tane)

 0/10 (Milk)(Me)

Persuasive writing (Fireworks ahould be banned)

Hello everyone,

For the first week of term in writing we were working on our persuasive writing skills, we were told to write about wether we thought firework should be banned or not. I worked with Isabella to make this peice of writing about why we belive fire works should be banned.

Fireworks should be banned

Do you like fireworks?

Well here are our reasons why we believe, you shouldn't use them

Although fireworks are in fact very pretty and can bring others closer it does pose a hazard when it comes to flammability since it releases sparks of fire from the gunpowder that if it’s around grass if there's enough of it can set the ground aflame. Since most people don’t keep water or a fire extinguisher around them while doing this it can be deadly.

Secondly, fireworks contain materials that are able to be used in other circumstances and can be useful (like different chemicals). If we use these in fireworks we could run out of the things used to make them when we need them in different situations. They also tend to cost a lot of money which can be used for other, more important things. Considering in this day and age everything is getting more expensive (which will include fireworks) putting that money into a bank account to save it would be much better in the long run.

Thirdly, fireworks tend to be loud, really loud. Loud noises tend to be bad for animals and can send them into shock, hurting them and maybe even killing them. Different animals can be useful in terms of nature and to society so if they die that would be very bad.

Thus we believe that fireworks should be banned

Bacteria

 Equipment

1. Agar dish

2. Cotton bud swab

3. vivid pen

Method

1. Collect the bacteria on a wet cotton bud swab from taps, keyboards, desks or anything that has bacteria on it

2.divide the agar in half by drawing a line on the lid

3.wipe swab into agar solution

4. put the petri dish into the incubator for a week to allow the bacteria to grow

5.draw and label a bacteria 

6.draw and label a scientific diagram of the experiment

S.P.I.L.E.S

Hello everyone, welcome to my blog

Today in one of our classes we were told to use SPILES (Social, physical, intellectual, likes, emotional, success)to tell people what we did during the hollidays. Here is what I came up with.

Social:My cousin and aunt came down from Wellington and I hung out with them. We went bowling, laser strike and we even went to hanmer springs.

Physical:I scootered to my holiday program and to the bus stop every day.
Intellectual:I read a few books and did math equations when I was bored.
Likes:I enjoyed hanging out with my cousin because we are very similar and get along well.

Emotional:Most of my holidays I was fine though there were some parts where I felt stressed, anxious and sad.

Success:I started learning Japanese again and I know a few basic phrases now.
