Science Fair Project Water Bottle Temperatures!! Type your category here (For the experimental design labs, the category is Physical Science) Danielle Lindsay
Statement of the Problem It seems that whenever your really tired and thirsty your water is never cold enough so I’m testing what type of water bottle will keep your water the coldest.
Project Overview I am going to have three types of water bottles and have room temperature water with exactly three ice cubes in each, then leave them in a dark room for an hour each with a lamp over them. This will be the artificial light. Then after that I am going to record the temperatures and see which water bottle kept the water the coldest and repeat this process.
Variables • the independent variable is the type of water bottle. • the dependant variable is the temperature of the water • The control group is going to be the plastic water bottle because this is considered the norm • The constants will be the amount of artificial light, ice cubes, time of day, the room, amount of water and the time I leave it in the bottle.
Hypothesis • My hypothesis is going to be that the metal/steel water bottle will keep the water the coldest after being left in the bottle for an hour with exactly three ice cubes.
Materials • Steel water bottle • Plastic water bottle • Glass water bottle • 750 ml of water to fill each • 9 ice cubes • A dark room • A lamp • A thermometer
Procedure • Gather materials • Label the 3 water bottles • Start experiment • Leave the water alone for an hour • Record temperatures of A B AND C • Analyze data • Make graphs/charts • Repeat the experiment
Data/Observations (Analyzes) • It is easier to understand the data if it is put into a table(s) and graph(s). • Create a graph(s) in Microsoft Excel and import it here. • Make sure all data is clearly labeled (TAILS). • List the data for both Qualitative Observations and Quantitative.
Conclusion What I discovered is that the steel water bottle kept the water the coldest. I think it kept it the coldest because it could retain it better. Metal or steel is just one of those materials that will absorb heat or cold really very well no matter what. The plastic did okay which is what my water bottle is so maybe that’s why it wasn’t as cold. The glass was kind of the in between for this project. It wasn’t the coldest but it wasn’t the warmest either. I think if you really weren't looking for that cold of water this is the best one but you cant find that many glass water bottles.
Possible Experimental Errors • I think one of my possible errors could be that I didn’t have enough artificial light or something like that. Or maybe I should have just used real light and gone outside and repeated the experiment more and tried different ways and see which one worked the best. I also think I could have used smaller bottles.
Applications and Recommendations • I suggest someone drinking the water and seeing which one is the coldest. Because if you did that you would have an opinion and data. I also recommend not doing this experiment in the summer because the summers in Arizona can change the temperature in any room inside or out. But other than that I don’t think theres anything else.
