THE POST!
Some problems that i think may arise are that i wont get enough people and my phone bills.
Developing EVERYTHING
okay here all my ideas developed:
1. HOW DOES A PHONE CONVERSATION AFFECT REACTION TIME???
i googled this and found this site and it had tips on how to do this experiment so I'm going to use this site as a reference
http://www.sciencebuddies.org/science-fair-projects/project_ideas/HumBeh_p009.shtml
i researched further and found that there were actually two ways to measure reaction time. i could use a ruler to measure or i could use a reaction measuring device on the internet; http://getyourwebsitehere.com/jswb/rttest01.html
so here are the variables;
- independent variable- the different distractions (i.e. using hands free or hands on mobile phone and no distractions-control)
- dependent variable- the reaction time
- controlled variable- the questions asked - the same indication of when to drop the ruler - gender - age - length of where the ruler is dropped - height at which the hand is to catch the ruler - which hand is being used - same questions being asked through the phone
2. Next idea, i think it should be how different types of water affects plants growth;
- independent variable- the type of water used (i.e. tap water, milk, tea, coffee, orange juice)
- dependent variable- how long the stem grows
- controlled variable- what type of seed is used - the amount of solution used everyday for every seed - the same location/ same amount of sunlight - same time of day when it is getting watered
- independent variable- the length of sting between the cups
- dependent variable- the sound coming from one can to another
- controlled variable - the size of the can - the type of string used - the same words or sentence being talked through - the type of cup being used(plastic, paper, tin can)
- independent variable- the colour of the pot
- dependent variable- the growth of the plant
- controlled variables- the type of pot - the same location - the same amount of water being used - same soil - same seed - same amount of sunlight
this idea was suggested by someone in a forum; http://classroom.all-science-fair-projects.com/forum/showthread.php?t=687
- independent variable- the temperature (freezer or under the sun)
- dependent variable- the change in colour or texture
- controlled variable- the tube that is going to be painted - the colour - the type of paint - how it is placed in the different areas

other IDEAS!
- The effect of temperature on paint
- Does the colour of the pot effect the growth of the plant
- Does the presence of digital noise reduce out ability to recognise images on television
TELEPHONE???
another IDEA
This idea led to another idea of what water is best used to grow plants like orange juice or milk(always wondered if the calcium would make the plant grow more) or tap water or boiled water...
RING A LING??
Since i put my title as RING A LING you would probably wonder why i like that title. Well 1. Its a good song 2. its my ring tone and 3. I LOVE THE NAME!!! but just so you wouldn't think that i was a crazy, obsessed lunatic or a very random person i thought i would do my srp on that goes ring a ling...a PHONE
Went searching and found this really good one that has something to do with a phone. found this awesome website http://www.sciencenewsforkids.org/pages/sciencefairzone/topics.asp and found one that was very interesting; How does talking on a cell phone or listening to music affect reaction time? i think we tested reaction time in year 8??? but this experiment involves a lot of people and that means a lot of paperwork. but looks doable
