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...................

goodbye pencil

HEYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYZ
this will probably be my last post
and the purpose of this blog
ends nowwwwww.
i have finished completely everything
of the srp
and im gonna hand the report in tomorrow!

it's been fun
:|

LAST BYEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE

dilema PENCIL!

HEYYYYYYYYYYZ
what the frog!
how do i draw lamps in a scientific diagram...
if the lamp is above the solar panel?

BYEEEEZ

edit 1: nvm solveddddddd it.

stupid pencil

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:

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

KTHANXBYEEEEEEEEEEEE

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

BYES

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

BYEEEEEEEEEEEEEEE

calculator pencil

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

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.

BYEEEEEEEEEEEEEEEEEEEEZ

sharp pencils

heyyyyyyyyyyyyyyyyyyyyyyyz
how's life?
anyways,
went to hurstville again to check
if they have any multimeters in stock
and they finally dooooooooooo
so i got it
its in my hands right now
im gonna do my second round
of the srp
TOMORROW NIGHT
after i finish my english homework :)

BYE.
