Anyone preparing/prepared for the IYPT?

[jangheej]

im preparing for the iypt this year, and for the iypt preliminary, i have to
conduct an experiment in only ten days!
can you help me get a sense of what to do??

Homework Statement

Air Drying
Table utensils, after being washed, dry differently. Investigate the drying time depending on relevant parameters.

Homework Equations

? haven't found yet.

The Attempt at a Solution

i'm searching for prior experiments, and I've tried keywords such as "drying experiment", "evaporation rate', "drying of solids", etc.. but not helpful at all :(
for now, I am thinking about placing plates of ceramic, plastic, glass, steel on a hot plate and heating until about 80degrees celcius, depositing a droplet of water with pipette, and measuring the drying time depending on different materials.
but its difficult to control and maintain the surface temperature of the solid plates and I am not sure whether this is the right approach to the problem.

can you give me some advice on how I should approach this problem?

The best way to approach this problem is to first think about the variables that you would like to measure. Some things you might want to consider include the surface area of the utensils, the temperature of the surrounding environment, and the humidity level. Once you have identified the variables that you wish to measure, you can then design an experiment to test them. For instance, you could set up a controlled environment with a hot plate and measure the time it takes for the utensils to dry in different temperatures and humidities. You could also vary the surface area of the utensils or use different materials to compare the drying time. It would also be beneficial to measure the evaporation rate at different temperatures and humidities by using a thermometer, a hygrometer, and a magnifying glass. Finally, you could create a graph to compare the results of your experiment.
