Goldilock principle

Goldilock principle

Off the internet

1. In astrobiology, the Goldilocks zone refers to the habitable zone around a star: As Stephen Hawking put it, "like Goldilocks, the development of intelligent life requires that planetary temperatures be 'just right'". The Rare Earth Hypothesis uses the Goldilocks principle in the argument that a planet must be neither too far away from nor too close to a star and galactic center to support life, while either extreme would result in a planet incapable of supporting life. Such a planet is colloquially called a "Goldilocks Planet". Paul Davies has argued for the extension of the principle to cover the selection of our universe from a (postulated) multiverse: "observers arise only in those universes where, like Goldilocks's porridge, things are by accident 'just right'".

2. In 'Goldilock and the Three Bears', Goldilock finds that only one bowl of porridge has the ''just right'' temperature, and in the same way within biology, you can find the 'just right' conditions -- called the Goldilocks principle. This research team has done by demonstrating that in order to get the 'just right' amount of signalling for symbiosis in the roots of legumes, a specific enzyme called chitinase (CHIT5) must be present.

3. Small planets, including Earth are much more likely to become incubators of life. Astronomers refer to these insignificant little worlds as terrestrial planets because they have heavy-metal cores surrounded by a rocky mantle. Terrestrial planets tend to stick close to their host stars, which means they have smaller orbits and much shorter years. Terrestrial or Earth-like planets are also more likely to lie in the Goldilocks zone. Also called the habitable zone or life zone, the Goldilocks region is an area of space in which a planet is just the right distance from its home star so that its surface is neither too hot nor too cold. Earth, of course, fills that bill, while Venus roasts and Mars exists as a frozen world. In between, the conditions are just right so that liquid water remains on the surface of the planet without freezing or evaporating out into space.

In my own words 

4. The goldilock principle for planets is when a planet is far enough away from the sun, so we won’t burn, but close enough so we don’t freeze. It is called the goldilocks principle because it is taken after the children fairytale where a little girl tries three different bowls of porridge and three different beds. One bed and one porridge where on one side of the scale (hot/hard) and another set were on the other side of the scale (cold/soft) whereas the last set of bed and food, were just right (temperature and firmness) Some planets are in the ‘just right’ place according to the sun/star they are orbiting. Any closer and any living thing would burn, any further away and they would freeze, they are just right.   

Carrot Cake Cupcakes

In Home Economics last week we made carrot cake cupcakes. We worked well as a team. We made these because they had a secret veggie hidden in them *carrot* so it was kinda healthy. There still was a lot of sugar.😉.Due to Budget and timing we could not put Cream cheese Icing on them, so instead we simply added icing sugar. We used a simple recipe of:

Cakes
- Flour
- White sugar
- Salt
- Carrots
- Cinnamon
- B.soda
- B. powder
- Oil
- Egg

Icing
- Cream Cheese (Softened)
- Icing sugar
- Lemon juice

Astronomy vs Astrology

In science we are looking at Astronomy. One of the things we looked at was  Astronomy vs Astrology. Astronomy is a real branch of science and deals with facts and evidence, whereas Astrology is a Pseudoscience (Pseudo is a greek word that means false or fraudulent)

Here is a video that explains it a bit

Here is a kinda funny one that I like.

Self directed learning goal

This week my self directed learning goal is to get my work done and on my blog and get up to date with all of my work as well.

here is are random pictures for you

Sorry I had to.

Earth Balloon

Earth Balloon

In social studies we are looking at sustainability. We did a small activity where we had a balloon that we had blown up and we got asked a bunch of questions and depending on our answers depends on whether we let air in or let it out. Our balloon ended up being quite small. We then had some questions to answer  

1. What happened to your earth?

It grew a little and shunk a little. It ended up being a small earth/balloon

2. Why did this happen?

Because we are kinda sustainable but not fully 

3. What could we do to stop that from happening? Or make it continue?

Break the bad habits we have and make new better ones 

4. What is one thing we could do to change our behavior?

Use both sides of paper, turn off a light as you leave the room.

Rotorua lakes (Unfinished)

In social studies we have looking sustainability and today we are looking Rotorua lakes and the water quality. the task is to write a newspaper article on it. 

notes
- the uses have changed from food resources to cloths and material resources.
- Pasture fertilisation/pasture runoff
- Farming stock effluent  
- Decomposing sewage – septic tanks and wastewater seepage

- rotorua city council

- The Bay of Plenty Regional Council

- NIWA (National Institute of Water and{Atmospheric Research, Ltd})

- Eight of the 12 lakes show at least possible improvement, Two lakes show no change, Two lakes show possible degradation
- people

questions
Describe why the lakes are a significant resource: Because it is a good food resources as well as cloths and material resources.
what human actions have contributed to the current water quality? Pasture fertilisation/pasture runoff (farming) Decomposing sewage (septic tanks and wastewater seepage)
Who has been responsible for the management of the lakes ? rotorua city council, The Bay of Plenty Regional Council, NIWA.
Identify key reasons why the future sustainability of the lake is at risk: Because people are stupid and do what they want without thinking of the coniquinces (spelling? spell check not working). 

The newspaper article (I have no Idea what I'm doing fyi)

The Rotorua lakes health is shown to be declining. This is because of things like Pasture fertilisation/pasture runoff running into the lakes and decomposing sewage, septic tanks and wastewater seepage. These lakes have been used as resources for food, clothes and material. People like the Rotorua City Council, The Bay of Plenty Regional Council and the NIWA (National Institute of Water and{Atmospheric Research, Ltd}).

Smoothies

In Home economics last week, we did a smoothie challenge where we had some ingredients that we had to use for the smoothies. My team had a rainbow blend that we had to use, which had strawberries, mango, kiwifruit, and blueberries. We also added milk, yogurt, oats and ice cream. The other teams smoothies were called

Cracking Coconut, which was a dairy free smoothie. In my opinion it had a very strong coconut smell and was lumpy. Their second try was around the same but was very watery.

Strawberry Blast, theirs was very smooth which was nice, and it was very pink, it was also quite perfumed. Part of me thinks they didn't take the tops off the strawberries because there was a planty undertone.

Banana Breezy, theirs was also quite smooth and it looked clean and fizzy. The taste was quite sweet and rich.

As we had a lot of our smoothie left we gave some to the teachers. This is their feedback
- totally delicious!
- yummy.
- love it. I can taste the blueberries.
- would be really yummy cold.
- Amazing! Loved how sweet it was without any sugar / honey added.
- Lots of different fruit that work well together.
- Darn that's good.
- Amazing! absolutely delicious.

Sustainability

In social studies we have been looking at Sustainability. I had to look at a Sustainability issue in New Zealand. I chose this one 

New Zealand has high greenhouse gas emissions per person.

New Zealand accounts for a fraction of the world's greenhouse gas emissions, about 0.17 per cent in 2014. But, on a per capita basis we have an outsized carbon footprint, emitting 18 tonnes of greenhouse gasses per person, every year. That makes New Zealand the 21st biggest per capita contributor to climate change in the world. Amongst the OECD (other rich nations which we benchmark ourselves against) we have the fifth highest per capita emissions. 

This is because New Zealand has around 10 million cows and 30 million sheep. Cows and sheep emit methane into the atmosphere and methane is considered 28 times worse for the planet than CO₂. One tonne of methane is 28 tonnes of CO₂-equivalent

 48% of our greenhouse gas emissions come from  Agriculture. 

People are changing to sustainable sources of energy, like solar, and are changing to electric cars, to reduce the CO2 levels in the air. Electric cars produce little or no local air pollution, reduce dependence on petroleum (Petrol) and also have the potential to reduce greenhouse gas emissions. People are also trying to stop using plastic, so it does not have to be made so factories aren't pumping chemicals into the air.

What can we do to help? We can drive and fly less, instead of driving we can walk or bike, it has the added benefit of being good for your health. If you don’t want to you can car-pool with friends or take public transport. We also plant trees, In New Zealand, forests offset nearly 30 percent of our greenhouse gas emissions. Trees also provide shade which has a cooling effect in towns and cities. When placed around buildings they can cut electricity used for cooling in summer.
