Abundance....

went to Aldi....bought 4 X 4packs of V (16 cans)...overhead this girl complaining to her 'nan' about how i was getting so many and she wasn't allowed to get one...felt a little guilty...until nanna looked at me with one of those old lady dirties so then i just grinned at her and skipped away with the cans humming 'a few of my favouirite things'(i'm pretty sure i felt burning on the back of my skull)...

SERIOUS NOTE: i plan to begin testing this week, either Tuesday or Wednesday

science 'inspires' me.....

I realise it might be a bit redundant to mention where i got the inspiration for this experiment now that i've already done the aim and hypothesis, but better never than late...which is exactly why i'm NOT telling you that the links to the websites for my research are in the sidebar labelled 'Research Links', and it is also why i am NOT displaying the original experiment testing reaction time, from the yr 9 co-ordination unit last year, in the space below.....

what to do, what to do, what to do, part 2

Aim, Hypothesis, Method etc.

NOTES:
- As of yet, i plan on making the given time 2 hours (preferably 3 hours) but if i cannot get enough people to do volunteer for that long, then i may reduce it to 1 and a half hours or possibly just one hour.
- I know the cup thing in step 9 is kind of a given, but just taking precautions...

moving on...


I plan to determine how the consumption of a certain quantity of energy drink effects the visual reaction time of humans over a given period of time.

I am hypothesising that the visual reaction time of humans lowers at a steady rate after the energy drink is consumed and will rise rapidly after reaching its lowest point.

Equipment:

- 30cm Ruler
- Table or Bench
- 15 Energy Drink cans
- mL measuring jug
- 30 cups
- Stopwatch
- Writing utensils (recording table)


Method:
1. Place forearm of human volunteer on the table/bench with open hand, palm facing horizontal, over ledge
2. Hold ruler vertically, immediately above volunteers' open hand
3. Release ruler, ensuring volunteer encloses hand around ruler as quickly as possible, without removing forearm from bench
4. Record, the distance on the ruler where it is clasped by the top of the volunteers' hand, into table
5. Repeat steps 1-4 twice more
6. Measure half of energy drink volume of can, into cup, using measuring jug
7. Start stopwatch as volunteer drinks contents of cup
8. Repeat steps 1-4 at 10 mins on stopwatch, also recording time steps were carried out. Continue doing so at 10 min intervals until stopwatch reaches 2 hrs
9. Repeat steps 1-8 with 29 other human volunteers, using a new cup for each volunteer

Out of Commission much?

It would be a really lame excuse to say that i did the graph and some research during the holidays but just didn't put it on my blog, but it's still true....

[I blame my pathological inability to do anything BEFORE i'm actually required to]

NOTE TO SELF: UPDATE REGULARLY!!!

Well anyway....to turning over a new piece of bark (leaves are overrated), here is my climatic graph....

Tpyos

I reaally need to wirk on quadriple chcking fort typos.

WhooPOOPsie daisy

I just re-re-read my blog entry (what to do, what to, what to do...) and realised that i said "IF energy effect reaction times in humans" a couple of times and other times i said "HOW energy drinks effect reaction time in humans"..... HOW is the one i'd meant to use.

I have 2 questions ....... I'll trade you for 3 answers

Just wondering, if i did the experiment involving humans.....
- Would the victims need to sign anything so i don't get sued or something?
- Does it matter how many people are tested?

What to do, what to do, what to do...

I still haven't completely decided exactly what experiment i'm going to do, but so far i really like the idea of involving soft drinks/energy drinks in my experiment. Right now i've got 3 experiments in mind....

1. How energy drinks effect reaction time in humans
2. How energy drinks effect memory in humans
3. Comparing how much fizz is created by shaking different soft drinks*

1. If energy drinks effect reaction time in humans

If i were to conduct an experiment to find out how energy drinks (e.g. 'Mother','V','Red Bull') effect reaction time in humans, i would probably use the ruler experiment conducted in science class last year during the co-ordination topic. It involved a centimeter ruler(vertical) being dropped just above someones open (palm facing sideways) hand, the amount of centimeters revealed at top of hand (cm = dependant variable) would indicate reaction times. I conduct this prcedure twice before the energy drink is taken, then twice ten minutes after the energy drink has been taken for an hour(unsure of time, maybe 40 or 50 mins)(time = independant variable). After all the results (cm) are recorded i will probably use a line graph to show the relationship between the human reaction time before the energy drinnk was consumed, to human reaction time after the energy drink was consumed. The hypothesis is a bit dodgy at the moment but in a nutshell would probably be something along the lines of:

"Energy drinks cause reaction times in humans to increase for approx. 40 mins after consuming, then decrease at a faster rate then it's increase."

This is my first choice as their seem to be less variables in this experiment compared my second and third options.
NOTE - Not sure if activites between ten minute intervals will effect reaction time and if it does it may be difficult to find a large amount of people willing to sit still for an hour (especially if they've to drink an energy drink)

2. How energy drinks effect memory in humans

This experiment would probably be conducted in the same way as the first experiment option, 'If energy drinks effect reaction time in humans', in regards to usiong time as the independant variable and testing the dependant variable twice before drinking the energy drink then twice at ten minute intervals for an hour. I then plan to read out a series of of numbers to see how many the victim (i wasn't sure what to call the person being experimented on) can recall (the amount of numbers recalled would be the dependant variable). The results will be tabulated then put into a line graph. As for the hypothesis, it would basically be the same as the first experiment options hypothesis, structure-wise:

"Energy drinks cause memory efficiency in humans to increase for approx. 40 mins after consuming, then decrease at a faster rate then it's increase."

* my third experiment idea is probably not going to be the one i'm going to choose, although it is preferable(aka FUN!), there would be too many variables (shaking during delivery from manufacturer to store, shaking at different strengths etc.)
