Energy @ Home Project

This term in Science, our grade has done a project on Energy in our homes. This project allowed us to analyse our enrgy consumption in detail. In the asssignment, we looked at how energy is transferred and transformed in the home, how energy is lost in the home and how to improve energy-efficiency in the home.

What I have learned in this project is how to read an electricity meter, how to correctly identify different light bulbs, and how to research accurately and create a report.

This will help me in the futuure for when I have to run a home myself. This has also helped me to set out my time much more evenly in order to complete an assignment. This project will be one of my milestones for life.

Energy At Home Science Project

The energy at home science project was very interesting, and heped me create new understandings. I learnt that lightbulbs aren't just lightbulbs. There are LED's, Halogens, Incandescents and many more, and all have a different impact on the environment. Just the section on lightbulbs made me more aware on what changes my family should make, and I am now making suggestions on what would save them more money and use less power.

Checking all the star ratings of my appliances made me much more aware of my family's power use. My washing machine is only 1 star out of 6, making it extremely inefficient. My dishwasher is only 2.5 stars out of 6, so it uses a lot of power. My fridge is 3 stars out of 6, so it is kind of efficient, and kind of inefficient. These appliances should all be replaced, ideally with 4 or 5 star machines. Replacing them would reduce energy use, and the power cost.

I also learnt that little things can make a big difference. For instance, on a sunny summer day I could leave most of the lights off, because if I leave them on the air conditioner would have to work harder because of the extra heat radiated from the lights. Making sure all lights are off and all power switches are turned off before I leave home could also make a significant difference.

This project has made me SOO much more aware of my family's energy use. I am now trying to make a difference, in my family's energy use, my family's energy cost and the environmental impact. And it's all thanks to this Energy At Home Science Project!

We went to the lab and completed the prac below found in Science World Chapter 12.1. The class has a ball completing this prac despite having to cremate some Tiny Teddy biscuits. Great insight into how we get energy from food. We also burnt some apricot slice and rice crackers. No pics or vid taken - sorry :(

What is Energy?

Get a Voki now!

One of the fundamental laws of physics says that energy cannot be created or destroyed, but it can be converted from one form to another.

Conversion is explaining that from motion energy(Kinetic energy) is converting into a other form of energy example potential.

Potenial energy is energy that can be use like magnetic, gravitional, chemical, electrical, elastic and nuclear. The picture of fireworks shows chemical energy.

Motion energy(Kinetic energy) is any moving object that users kinetic energy. Like heat, light, sound and kinetic energy.

The sun shows energy of heat.
