If you take a thermo flask full of English tap water and another thermo flask of filtered water and pour them into seperate dishes in the a normal area (where no one is interferring with the temperature, fans etc.)and leave them for 15 minutes. After the time has expired take the temprature and see which one is the coldest. Also see if they have frozen at all. I would like the experiment to happen 3 times in 1 day.
9:00am, 12:00am, 6pm and see whether the time of day affects the tempreature. I would predict that the midday experiment would show that it is warmer then than anytime time else generaly.
I think my experiment should win because it is simple and easy to do and will prove just which water (filtered or tap)cools the quickest.
You will need:
6 thermo flasks
tap water
filtered water
thermometor
results chart
2 bowls
HERE ARE YOUR INSTRUCTIONS DR ROGERS!!!
1. Bring both thermo flasks with water in and pour them into seperate bowls.
2.This must be done at 9:00am. Leave them for 15 minutes then take tempreature of water.
3.At 12:00am repeat this with another 2 thermo flasks.
4.Reapeat with fresh water again, take final tempreature and record all results in a table and report back to the website!!!
My name is Dawn and I’m 11 years old. Good Luck and I hope I win!
