Bunsen Flames

 Today/Yesterday for Science we set up the Bunsen burners and then figured out what the difference was between the safety flame ( orange ) temperature and roaring flame ( blue ) temperature on a Bunsen burner by warming Water. The starting temperature of the water ( in a beaker ) was 11 degrees then when we warmed the water for 5 minutes on a safety flame we got up to 50 degrees, The roaring flame also starting at 11 degrees it got up to 53 also warming for 5 minutes. 

Which wasn't much of a difference considering other groups got differences of 20--100. Then we had to figure out the average of all the groups temperatures by adding all the temperatures together then divide it by 7, I didn't figure it out but it was quite high with over 200 then divided it by 7 so it was around 35. Here's a photo of the roaring flame ( blue ) and the safety flame ( orange )

Evaluate the practical.

We need to make the test fair so that everyone is at the same stage and some people aren't struggling more than others.

We need to make sure everyone has the same thing and same equipment to keep it fair for everyone.

It was half and half a fair test because some people didn't warm it for exactly 5 minutes,some of us took the thermometer out early lastly people had different amounts of water.

this experiment could be improved by everyone starting and finishing at the same time all ready and have a specific measurement to make it as close as possible
