My Inquiry/Big Idea

POWER/ENERGY

What type of power is most energy efficient?

Electricity is the most efficient source of power, for heating and lighting for example.

It is a clean energy source and does not lose any of its power, like coal does when it burns.  However electricity is now a primary power source like wind and solar energy is.  

The most efficient  generator of electricity is hydroelectric such as a dam which can be up to 95% efficient, although initively it is very expensive to build.

Other electricity generating methods are no more the 50% efficient at best, e.g. the best are solar generators.  Nuclear power plants are also very efficient.  

My questions:

1. Can solar energy be used in domestic places?

2. Could you run your whole house on solar energy alone?

3. Where can you put solar panels around your home?

4. Which way should solar panels should be facing?

5. Is electricity the most efficient power source?

6. What is produced by a wind farm?

7. Is an open fire an efficient heater?

8. How expensive is electricity?

Answers:

1. Yes it can be use as electricity and heating of hot water.

2. Yes you can if you are careful with the way you use it.  On cold, wintery days, the water system may not be as hot as it could on a bright day.  If you have alot of people/user this could drain the energy quicker to not last the day.

3. The best place to put your solar panels is on your roof as this is a high point without shade/shadows.

4. Facing North is the best place to capture the Sun.

5. Yes it is as you can tell by reading my review on energy use.

6. Electricity from the blades of the big windmills to capture the wind.

7. No it is not as it pollutes the air however the beauty of an open fire is that is can give ambience to your home which can make you feel warmer.

8. This will depend on your useage and where you source your energy.  For example solar panels will have an initial layout for cost, but long term it will and should pay for itself.  Energy companies have various plans and their rate will be based on this with your use.

100 word challenge

It was a hot summers day at the beach and the sea hissed over the sand. I opened the lid of the picnic basket and smelled the salami and bacon sandwiches,my favourite. I reached in and felt the soft marshmallows squish in my fingers. The lemonade fizzed in the bottle as I lifted it out. It felt cold and slippery to touch. The lemonade popped like candyfloss in my mouth as I drank it.  I took the lid off the container of salt and vinegar chips,my favourite,and crunched on one. It was salty to taste and dissolved on my tongue in seconds.

It was a blur of red,it rocked past me, it was the flash. The bank robbers did not stand a chance 100, 200, 300 kilometers an hour he sped towards them.  It was only a matter of seconds and he would be on to them, but a ferocious wind followed him and swept past all the cars, breaking all the car windows. The wind was so strong that I was flung off the path. I got up quickly to see him go but there was nothing to see but people's broken glass doors.  I turned and walked home.

My favourite series

My favourite book series:

CONSPIRACY 365

This series is a run from the cops / fighting. This is one of my favourite series because it is a boy who is trying to find his Dads secret but his Dad died and he has one year to find his Dads secret. However he is also getting chased down by the cops and when he does find it he gets lots of money but other people are trying to get it too.

What I learnt T2W4

SCIENCE:

Last week in science i learnt that copper and aluminium are two of the best heat conductors

MATHS:

In maths I learnt about Integer. Integer are not a fraction they are all whole numbers either positive or negative for an example:-

+7--4=+3

HOMEROOM:

In home room we are learning sustainable design/how to make an efficient but not too expensive home.

My 100 Word Challenge

The bird kicked him off the stump. The Lego man took 2 hours to climbed back up to find the bird was still there, he moaned and groaned as he wanted the food. Again kicked off, he went to another stump and 2 hours later reaching the top the same bird was there. The Lego man realised that he had gone around the stump instead of going to a new one. Now very hungry he ran at the food and ate it, the bird did nothing so he kept on eating, and still the bird just stayed still. Lego man then realised that he was boss of the bird now.
