Science Buddies: "Ask an Expert"

Allo, Our science project is finished. It was exploreing the properties of of salt water as a secondary coolant, aka "brine". We experimented on NaCl, CaCl, and MgCl, using 100 ice cubes a thermomator, and dozens of 12-oz cans of sprite. We made 4 trials, with Iv's of,4 concentrations of each 3 salts, and 3 differentlengths of time the soda was exposed, or submerged in the Brine. Also,our DV was CHANGE IN TEMPERATURE OF THE SODA. for exanple, NaCl at 30% salt by mass of the water and ice-after 10 minutes of submersion lowered the temp 14 degrees C, Initial temperature was 16 degrees C, so it got pretty cold. We have made graphs that show preformence of each brine using the mean of the anerages of the trails, we also measured the range of the trials. What we need to know: is there any other way of analyzing the data we have. Any and all replies are thanked.

Hi Dan and Tom!

I would suggest a line chart of the data you collected. A bar chart may work, but I don't think it's likely.

There are several other graphing options. Please provide "what are the different types of graphs?" to answers.com to explore. Thanks.
