Hello, sorry I haven't written a post in a while!
In class last term and the beginning of this term, my class have been working on our separate Science Fair projects. We have all spent most of last term, our holidays, and this first week to get our projects completed. Most of us are almost completed, all of us are busy cutting, gluing, backing and printing, finishing off our Science Fair boards to a high standard.
My project started off badly, as it didn't work at all. But once I changed my method, it started to work. (Which I was extremely grateful for!) I have now almost completed my board, I'm just cutting and gluing.
My aim was : To investigate whether you can play a simple tune by altering sound waves with coloured light."
My actual experiment was connecting a speaker to a solar panel through a parallel circuit. (click here for a good website that explains them well) I then shone a torch into a solar panel, and the light waves caused the vibrations in the speaker to change the pitch. I then shone different coloured lights, to see if this caused different pitches in note. This did work, however, I did not get a definite note for each colour. The colours I used were red, green, yellow and blue, as these are four of the colours that makes up white light.
While I'm here, I would like to say a few thank you's. Mrs Hogg, for keeping track of my work, proof-reading, and getting the guillotine for everyone in the class.
Mrs Dromgool, for helping me develop my initial idea, and letting me borrow some equipments.
My mum, for using your highlighting skills when proof-reading my work, and helping me with presenting my board.
And finally, my dad, with out you, my Science Fair would have been reduced to a baking soda and vinegar volcano. You helped me with all things technical, proof-read and proof-read again my work, and put up with hundreds upon thousands of questions, most of them repeated, because I had forgotten the answer.
Thank you to you all, I couldn't have done it without you!
