Question

Which cup of water will evaporate the fastest if it is

put in different places?

Equipment/Tools/Materials

3 cups (same)

600ml of water

Scale

Balcony, Fridge and Room

Hypothesis

My hypothesis is that the water in the room will evaporate the fastest because the room temperature is warmer then

the fridge and the balcony.

Variables

Same:

Amount of water

Time of checking the amount of water

Cups

Scale

Difference:

Places where the water is (Room, Fridge, Balcony)

Procedure

First, I will get three cups of 200ml water.(same)

Then, I will put the cups one in the room, one in the fridge, and one on the balcony.

Everyday, I will check the water at 4:10pm.

At last, I will make a chart of the results.

I am going to do everything twice for accuracy.

First Time Results

Room Balcony Fridge

Day 1 195ml 197ml 199ml

Day 2 189ml 194ml 199ml

Day 3 182ml 190ml 199ml

Day 4 175ml 185ml 198ml

Day 5 169ml 184ml 198ml

Day 6 160ml 181ml 197ml

Day 7 154ml 176ml 197ml

Second Time Results

Room Balcony Fridge

Day 1 195ml 192ml 200ml

Day 2 189ml 181ml 199ml

Day 3 184ml 177ml 198ml

Day 4 177ml 176ml 197ml

Day 5 173ml 171ml 196ml

Day 6 168ml 160ml 196ml

Day 7 165ml 156ml 195ml

Conclusion

The first time, the water in the room evaporated the fastest, which I expected. The second time, the water in the balcony evaporated the fastest, because the temperature rose 5 degrees, so the water evaporated the fastest. I now think there is no accurate answer, because the temperature is different all he time. You can not control the temperature outside.
