forgot pencil

HEYYYYZ
I'm backkk.
i felt like,
i shouldve said a bit more
to close this blog properly
for the final time
forever.

I started this srp, not knowing what to do.
...and i still don't.
but.
i decided to conduct an experiment
that will somewhat impact the globe
in some way
just baby steps.
then i went thru
global issues
like...........
poverty, and others
then i thought:
mass use of fossil fuel -> global warming -> renewable energy -> solar energy -> solar panel -> COLOURS OF LIGHT BAM.

so i started brainstorming
and came up with this srp experiment.

the purpose was to find out
which colours of light
will produce more solar energy.
because i thought,
not a lot of people care about solar energy
because they think
its not efficient
its too much trouble.
its not as reliable
nobody else is using solar energy, why should i
not a lot of people invest in it, it's probly dodgy.
well, i got thinking..
if i can somehow conduct
an experiment
that will further the development of solar panels
then, people will begin to trust it more
and use it more.

so i was thinking,
there's different output of colours of light
throughout the day
for example, sunrise and sunset...
less red. yada yada yada
if i can find out which colour of light produces more energy
then, this can be a veryyyy awesome advantage as
it will improve soar panels
to store maximum solar energy and produce maximum electricity
throughout the day
people will be able to build better and improved solar panels
through my research
and they'll name a solar panel after me
im gonna be on wikipedia.

anyways, less rambling.
so I hypothesised that red light will produce less solar energy
and violet light more solar energy than other colours of light.
based on plank's equation (see my previous post on planck's equation)

and i tested this hypothesis
by measuring the electrical energy produced
by each colour of light from a solar panel

However, after producing the graphs
i realised my hypothesis failed badly
and i was a bit dissappointed.
the graphs show that
red doesnt produce less energy,
blue did.
and violet doesn't produce more energy than other colours.
noooooooooooooooooooo.

but i didnt stop there.
oh no.
i figure the errors
and realised
the cellophane betrayed me.
but there was nothing i can do.
because i bought the cellophanes from hallmark
same brand.
there were other possible errors too
they're in the report.
but yeah.

at least, a potential famous newton the second
will come along
and read my report
and imrpove from it
and become super famous
and pay me some money for contributing in his research
who knows.
maybe my report
will become part of a yr 7 cirriculum
after i die

but yeah,
after all that effort
hypothesis was proved INVALID

it was a very enriching experience
woot.

BYE FOR EVER...................

HEY.
if you havent already read my previous blog post,
btw, you should read my blog posts chronologically
it lessens confusionn.
anyways, in my last blog post,
i explained why its important to do a 4th round
instead of just 3
anyways
i did the 4th round LAST NIGHT
here are the results:

start time: 9:01pm
end time: 10:32pm
date: 12th june

ugh pencil

HEYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYZ

okay i forgot to post a post
about how I did the third round of the srp
like 3 days ago
it went very well
here are the results:

date of experiment: 9th of June, 2010
start: 9:05pm
finish: 10:26pm

click for larger

i was really happy that i finished the third round and the experiment overall
BUT. i realised that i only did one light bulb for the first round
so therefore, im gonna have to do a 4th round
to compare the results between the three light bulbs
im still gonna talk about the first round of the experiment
in my report tho
since it's pretty important because
it had a lot of errors
and ppl will be able to see the improvements i've made
since the 1st round

HI.

Alright I'm now gonna provide you with info on the second round of the experiment which I did a couple of days ago.

Started: 9:07pm
Finished: 10:29pm
Light bulbs = 75W, 60W, 100W

Raw results:

click for larger

As you can see from my previous post about the errors in the first round of the experiment...in the second round, I have tried eliminating the errors by:

1)having the same person with the same role throughout the experiment - so I recorded the readings while dad held the filters throughout the whole thing, less confusion and smoother flow as a result

2) bought clips to connect the wires and hold it down together - prevented the trembling hands problem, very stable, unjumping readings as a result

HEYYYYYYYYYYYYYYYZ
the long awaited photo blog is here
let's break it down
woot.

okay here's photos of my equipments separately:
(click on the photos for larger view)

Digital Multimeter

Solar Module 2.0volt 200mA: 94mm X 63mm

Phillips 75W(it's inside the 40W box), 60W and 100W

Cellophane colour filters(from top left to bottom right): yellow, purple, green, blue

(from top to bottom): orange(it looks yellow, but it really isn't) and red

Here's an epic photo of the experiment,
the man hands belong to my dad

i posted two posts in a day
which means, i'll post the second round results tomorrow
to space out the posts a bit

I hope you're happy.

BYESSSSSSSSSSSSSSSSSSSSSS

broken pencil

HEYYYYYYYYYYYYYYYYYYYYYZ.
I did my second round of the experiment last night,
which was more organised than the first round.
Why? Because I changed the method a bit after doing the first round.
To recap on the first round...
I only did one light bulb (60W) in the first round.
Some time after, I added in a 40W and 100W light bulbs in the method and equipment list, remember?

Okay anyways, last night, we thought we had all three types of light bulb readily
in our home.
However, we couldn't find a 40W light bulb, like ohmg.
So anyways, we found a 70W light bulb to replace 40W...
So I'm changing the method and equipment list to:

Equipments:
⚨ Solar Module 2.0 Volt 200mA (referred as "Solar Panel" in the method section)
⚨ 2 wires
⚨ Multimeter
⚨ Electric Lamp
⚨ ~~40W~~75W, 60W and 100W light bulbs
⚨ Colour Filters (red, orange, yellow, green, blue, violet)
⚨ Dark room

Method:
1. Connect one wire from the positive pole of the solar panel to the positive pole of the multimeter.

2. Connect one wire from the negative pole of the solar panel to the negative pole of the multimeter.

3. Set the multimeter to measure the voltage.

4. Place the red colour filter in front of a ~~40W~~75W light.

5. Place the solar panel at a distance of 120mm to the light bulb vertically above.

6. Observe the multimeter and record the reading shown.

7. Repeat steps 4 - 6 for the other 5 colours and also perform the same steps without any colour filter.

8. Set the multimeter to measure the current.

9. Repeat steps 4 - 7.

10. Repeat steps 4 - 9 with a 60W light bulb.

11. Repeat steps 4 - 9 with a 100W light bulb.

_________________________________________________________________

Oh btw, have I told you the team members of the SRP?
It's me and my dad.
Moving on,
I'm also gonna recap on the errors of the first round...

human errors:
1) connection of wires - used human hands to connect wires which caused trembling - therefore the readings shown on the multimeter kept jumping and cannot be kept constant.

2) filter might not have fully covered the lamp - because me and my dad swapped roles (holding the filters, and reading and recording results) halfway through the experiment because I felt sorry for the old man for holding it so long - therefore, experiment might not be consistent in its results.

systematic errors:
1) the accuracy of the multimeter - might be manufacturer's fault for producing dodgy quality - it's not certain if the readings the multimeter produce is accurate

2) solar panel's output of energy - may not be constant under the same amount of light energy - it's manufacturer's fault - nothing can be done about it, too bad.

graphite pencil

Heyyyyzz..
I've just been browsing other people's blogs,
and everyone's writing their's in formal language.
So I feel compelled to do the same from now on.
Okay, so the method is due tomorrow.
Here it is now, I've revised it a bit since my last post.

Aim: To find out if the power generated by a solar panel will vary with different colours of light.

Hypothesis: All colours of light generates the same amount of energy.

Equipments:
⚨ Solar Module 2.0 Volt 200mA (referred as "Solar Panel" in the method section)
⚨ 2 wires
⚨ Multimeter
⚨ Electric Lamp
⚨ 40W, 60W and 100W light bulbs
⚨ Colour Filters (red, orange, yellow, green, blue, violet)
⚨ Dark room

Method:
1. Connect one wire from the positive pole of the solar panel to the positive pole of the multimeter.

2. Connect one wire from the negative pole of the solar panel to the negative pole of the multimeter.

3. Set the multimeter to measure the voltage.

4. Place the red colour filter in front of a 40W light.

5. Place the solar panel at a distance of 120mm to the light bulb vertically above.

6. Observe the multimeter and record the reading shown.

7. Repeat steps 4 - 6 for the other 5 colours and also perform the same steps without any colour filter.

8. Set the multimeter to measure the current.

9. Repeat steps 4 - 7.

10. Repeat steps 4 - 9 with a 60W light bulb.

11. Repeat steps 4 - 9 with a 100W light bulb.

LOLJK pencil

HEYYYYYYYYYYYYYYYZ.

OKAY.
i've been bad
'cause i haven't bought the equipments yet
im a little short of money right now
its also really inconvenient for me
because
dicksmiths is all the way in hurstville
the one where i live doesnt even have
a multimeter
so dodgy

anyways i promise i shall
put the method up soon!!!!
i've already written a final draft for it
i just need to check a few things

also, i promise
i'll post a blog post
entirely based
on photos of my equipments
and experiment
i just need to get the equipments first

yes, so many promises
in just one post
anyways ive also started
my srp project thing
i've written like the aim
and the hypothesis
which is great!
not sure if we even need the hypothesis
i promise i'll ask someone smart
tomorrow
anyways...........

alright, i wasn't able to go dicksmiths in hurstville
the other day
so i'll just have to go this weekend then
to rebuy my equipments
since i refunded it the other day.
i need to redo my experiment
because there were a lot of errors

eye pencil

helllllloooooooooos

i did the experiment last night
and finished it just before biggest loser finale started
killed two stones with a bird
yep yep
anyways,
here are my results
they're not yet tabulated/organised
but yeah.
just giving you like
an insight to the preliminary stages
of my assignment?

...

distance from light bulb to solar panel = 120mm
light bulb (Phillips)= 60 W
Size of Solar Panel = 94mm X 63mm
name of solar panel = Solar Module 2.0 Volt 200mA
Filter size = 13cm X 17cm

Current
Red - 54.3 mAmp, 54.1 mAmp, 54.7mAmp
Orange - 57.9 mAmp, 57.9 mAmp, 58.0mAmp
Yellow (mAmp) - 58.2, 57.7, 58.0
Green (mAmp) - 52.8, 52.8, 53.5
Blue - 49.5, 49.5, 49.6
Purple - 52.5, 52.0, 52.9
No filters - 61.2, 61.6, 61.8

voltage (volt)
Red - 2.01, 2, 1.99
Orange - 2.02, 2.01, 2
Yellow- 2.02, 2.01, 2
Green - 2, 2, 1.97
blue - 1.99, 1.98, 1.96
Purple - 2, 1.99, 1.97
no filters - 2.03, 2.03, 2.01

and there were a lot of fails
....when touching the wires
of the solar panel with the pointy bits of the wire
of the multimeter
my hands were quivering/shivering
and made the readings on the multimeter jump a lot
solution of this is:
i taped the wires down onto the table
and the readings on the multimeter didn't jump

but i shall record these errors in another time
properly and precisely in the report
dont you worry..
i apologise if it seems messy and unorderly right now
but trust me, i've got it all covered.

okay byeeez

thick pencil

Hellooooooooooooooooos.

I feel like compiling a budget list.
I like making lists.
(and also to make it seem like I've been active a lot on this blog)

initial budget: like about 5 bucks
ended up spending: like about a gajillion zimbabwe dollars...FORTY AUD

1) Solar Panel = 15 dorras, dicksmiths
2) Multimeter = 17 bucks man. ,tandy
3) Lamp = i already got one... ,home
4) Cardboard to encircle lamp = found one on the street ,victoria av.
5) Red cello = 1 dollar ,go-lo
6) Orange, Green, Purple cello (hallmark) = $5.85 ,newsagency
7) Yellow and Blue Cellophane = home
8) cardboard make a support frame to hold the cello = $1.19 ,go-lo man!
10) Dark room = yeah free.

Btw, I'm spending my OWN money on this. 40 dollars i'll never be able to get back...and give to the poor. D:

BYESSSS.

edit 1 (19th April, 2010): apparently i lived in a cave
because there's actually this magical thing
called A REFUND which i just realised today
so i ended spending only like 7 dollars
which exceeded my original budget by
2 dollars
LOL, just ignore this pointless post... :/

What colour of light will produce the maximum amount of electricity in a solar panel?

Aim: To find out if the power generated by a solar panel will vary with different colours of light.

Hypothesis: All colours of light generates the same amount of energy.

Equipments:
⚨ Solar Panel
⚨ 4 wires
⚨ Multimeter
⚨ Resistor
⚨ Lamp with cardboard encircled around the light, leaving an opening
⚨ 40W, 60W and 100W light bulbs
⚨ Colour filters (red, orange, yellow, green, blue, violet)
⚨ Dark room

Method:
1. Connect one wire from the positive pole of the solar panel to the positive pole of the resistor and another wire to the positive pole of the voltmeter.

2. Connect one wire from the negative pole of the solar panel to the negative pole of the resistor, and another wire to the negative pole of the voltmeter.

3. Place the red colour filter in front of a 40W light

4. Place the solar panel underneath this now coloured light.

5. Observe the voltmeter and record the volts shown.

6. Repeat steps 4 - 5 for the other 5 colours and also perform the same steps without any colour filter.

7. Repeat steps 3-6 with a 60W light,

8. Repeat steps 3-6 with a 100W light.

Of course, this is just an early stage of the assignment, so this report might need a little revising as I move along. But here's the general idea.

BYEEE!

Hellooooooooooooooooo~!

Turns out equipment can't be borrowed from school D:
I need to head over to Dick Smiths this weekend
to get a multimeter.

And also, instead of buying a light box, I'm just going to find a straight cylindrical cardboard tape around the lamp.

I also revised the equipment list. Check it out, woohoo:

~~⚨ Solar Panel~~
⚨ Multimeter
⚨ Resistor
~~⚨ Lamp with cardboard encircled around the light, leaving an opening~~
~~⚨ Colour filters (red, orange, yellow,~~ green, blue, violet)
~~⚨ Dark room~~

Hellooooooooooooooooo!

Okay, today I bought some cellophane coloured paper.

Cellophane. Mister Cellophane. Shoulda been my name. Mister Cellophane

I bought just yellow, orange and red because I couldn't find any other colours in the store.

Something like this (found it on google):

I still need to get green, blue and violet...

Btw, just to recap, I'm doing this question:

4) What colour of light will produce the maximum amount of electricity in a solar panel?

I came up with this question because I reckon it relates to global issue, kinda? Like global warming is happening now...resources running out...people using solar panels more and more...yer know? :)

charcoal pencil

Helloooooooooooooooooo!

Okay, this is stupid. Where am I going to find an ammeter, voltmeter, resistor and light box???

I can't just use my lamp, because the light spreads out. I need a light box with like un-dispersed light.

Wait, can we borrow from the school? Remind me to ask Ms Zhang later.

Anyways, I still need to buy colour filters/transparent paper. Today, my dad bought this electronic photo frame, and it came with a medium sized frame. I'm going to use the frame to stick my colour transparent paper on for the light to shine through.

Here's an updated list of equipments I still need to get, the striked words means that I already got them:

~~⚨ Solar Panel~~
⚨ Voltmeter
⚨ Ammeter
⚨ Resistor
⚨ Light Box
⚨ Colour filters (red, orange, yellow, green, blue, violet)
⚨ ~~Dark room~~

Helloooooooooooooooo!

On my last blog, I told y'all that I have decided to do question 4. But I haven't really explained why I chose that, and why I didn't choose the others. Lemme just analyse these by naming the independent and dependent variables and also listing the things I should consider if doing that question.

Key: the pink underlined words = independent variable
the green italiced words = dependent variable

1) What is the effect of the temperature on the solubility of salt?
⚨ amount of solvent
⚨ type of salt
⚨ the amount of air pressure

2) Is the extension of a spring in proportion to the force applied on it?
⚨ different types of weights (5, 10 kg)
⚨ material/type of spring (if it's tight, or loose/floppy)
⚨ where to attach the top end of the spring to
⚨ define extension (length of the spring after hanging the weight minus the length of the spring without any weight hanging from it)
⚨ weights must be within reasonable range (can't be too big, otherwise it'll break the spring, and can't be too small, otherwise it won't cause any changes to the spring)
⚨ measurement (cm)

3) Does the surface of a piece of bread with jam on one side always faces downwards when the bread falls?
⚨ height of fall
⚨ weight of bread
⚨ amount of jam
⚨ surface area of bread
⚨ use same type of jam and bread

4) What colour of light will produce the maximum amount of electricity in a solar panel?
⚨ type of solar panel
⚨ surface area of solar panel
⚨ angle of incidence of light
⚨ amount of light
⚨ type of colour filters
⚨ type of voltmeter and ammeter to measure electricity generated

5) Will the presence of impurities affect the melting point of ice?
⚨ type of impurities
⚨ amount of ice
⚨ shape of ice (ice cube, ice sphere)
⚨ surface area of ice
⚨ type of thermometer
⚨ amount of impurities
⚨ room temperature

6) Does the weight of a pendulum ball affect the number of swings per minute?
⚨ type of pendulum ball (metal, wood)
⚨ shape of pendulum ball (cube, sphere, triangular prism)
⚨ weight of pendulum ball
⚨ length of the string attached to the ball
⚨ height of pendulum ball raised
⚨ type of stop watch (digital, analogue clock)
⚨ environment (steady or not? wind or not?)

Helloooooooooo!
Today I discussed about my SRP to my dad
since he is the smart one in the house.
Anyways, I came up with several topics/questions for the SRP.

1) What is the effect of the temperature on the solubility of salt?
2) Is the extension of a spring in proportion to the force applied on it?
3) Does the surface of a piece of bread with jam on one side always faces downwards when the bread falls?
4) What colour of light will produce the maximum amount of electricity in a solar panel?
5) Will the presence of impurities affect the melting point of ice?
6) Does the weight of a pendulum ball affect the number of swings per minute?

Then, I asked Ms Zhang for her opinion about the topics I came up with.
And she said that she prefers the solar panel question.

But my dad thinks that the pendulum ball question is best. I even found a picture on google on how to set it up.

I trust Ms Zhang's opinion better, so I guess I'll go with the solar panel question then. :)

I found this site on how to make a solar panel:
http://www.instructables.com/id/Small-Solar-Panel/

Not sure if I'll use that site, just throwing it in here. I'll probably just buy it from Dick Smiths, if it's not too expensive. Remind me to search the price of solar panels later.

Bye'
