The world is full of electrical technologies that help our lives.
Magnetic locks, spark plugs, fuseboards, motors,
speakers, touchpads, the list goes on!
Your group is going to be designing, making and testing an invention. This is something that uses electricity to do a job or solve a problem.
Some ideas for inventions are here
You can try one of those, or your own idea but
 make sure you run it by your teacher first.
Lesson 1: Our Goal
What are you going to try to make?
A Candle alarm clock
Has it been checked by the teacher?
Yas


Lesson 1: Our Plan
Draw a diagram of how you think your invention is going to be assembled.

The diagram should be good enough someone else could make it the same way as you.
     
What parts are you going to need?
  • A candle wires
  • a metal can
  • Battery
  • buzzer
  • ruler
  • timer
  • fire
What safety concerns are there when making/using this invention?
  • Burnt
  • setting things
  • a light
Has it been checked by the teacher?
yas
Now you can go assemble and test your invention!
Lesson 2: Our Invention
What changes did you have to make from your original plan?

Why did you make these changes?
Getting a longer candle so we have more to do experiments on


Lesson 2: Testing our invention

How well does your invention work?
It worked alright but next time we need to change so things to make it better and for it to work to the best it can
What could you do to make it work better in the future?
Make the metal that makes the light turn on more sustainable so that it works all the time when the paper clip drops/touches/leans.


Lesson 3: How it works
Draw a circuit diagram showing how your invention is connected.

You might need to look up some symbols for unusual components you
have used.





Explain how your invention works. Use what you have learned about electricity in
class to do this.
First you wonder in how long do you want the alarm to go off in as the wax off the candle melts. Then put a paper clip in where that time measures into. We then put a piece of thin metal (youse could use tin foil or the metal from a drink can) just under where you put the paper clip. And when the candle melts down to there the paper clip will either fall or droop onto the metal piece. In the drawing above is the circuit on how the alarm actually goes off.   
What is a real world use for the device
you have made?
A real world use for this device (the candle alarm clock) would be to wake people up in the mornings so it doesn’t use as much electricity. Using this will teach people about electricity and saving it.

P: We didn't have to take a test
M: we had to carve a candle a lot
I: how we made it

Firsts Paragraphs ENGLISH 2018

By Anonymous -
My focus was to find out who the first person to be legally executed by electric chair was. Before researching the topic I knew a little bit about it, but both of these sites opened my mind to new knowledge about my chosen topic that I would never of known before such as the prison, who came up with the idea and the work that went into making and testing the chair to see if it was efficient. My 2 sources were history.com and wikipedia . I was interested in this topic because i’ve watched a few death row documentaries and it’s fascinating to me because we don’t have the death penalty so it just shows me another side to how other countries run their criminal system. The first source, history.com provided quality and descriptive information surrounding my question. It indicated to me where the execution happened, how the chair was manufactured and details around whose idea it was and the amount of volts used. The site discussed the actual inmate William Kemmler, who g

ENGLISH Sewell Peak Experience

By Anonymous -
The walk up Sewell peak was exactly what I was expecting it to be like. My goals were to be one of the first people up there and to not get annoyed at people and be patient. I achieved one of these. I walked up with Grace and we came in the top 10 and the first girls. The other goal I set, I didn't think I was going to achieve based on how I act but I'm still really proud of everything else I did. The reason behind Mr England wanting use to do that is about NCEA and aspects of life. NCEA is the mountain and by climbing it and making our way over the hills or bumps we are making it to the top and to a view we have never seen before. To have this feeling of satisfaction and triumph after a huge accomplishment. And to see how grateful we should be for the town we have and to get a new perspective of it. It was basically a metaphor for next year and the years coming after that about perseverance and determination. I feel like in ways I did have this realisation of a few things th
