Question: What is the effect of the size and shape of a container on its evaporation?
I chose this topic because it interested me and I was curious to how the shape of a container affects its evaporation rate.
Independent Variable: Size and shape of a container
Dependent Variable: Evaporation
Constants:
1. Type of containers (plastic) 2. Amount of water 3. A place where the evaporation rate won’t be affected.
Hypothesis:
If the size of a container is large and the shape is circle, then the chances of evaporation will increase because there’s more exposed molecules in a large and circle container. When water is exposed to more molecules, then there are more chances of evaporation because with more molecules, there’s more space for water to evaporate.
I decided my hypothesis after reading a article online written by a hydrologist. It explained that when there’s more area, then the evaporation rate will increase.
Materials:
Water- 140 ml per container
Graduated Cylinder
1 Large circle container
1 Medium square container
1 Small circle container
1 Large square container
1 Medium square container
1 Small square container
Procedure:
Step 1: First, the water (140) was poured into the graduated cylinder. Step 2: Next, each bowl was filled with 140 ml each. Step 3: Then, the water was placed in an area where its evaporation rate will not be affected. Step 4: After 4 days, the water in the container was checked again. Step 5: Then, each container was measured accordingly in the graduated cylinder to check how much water had remained. Step 6: After that, a chart was drawn to add in all measurements for the containers which makes it easier to understand your data. (UNITS WERE INCLUDED, ML!!) Step 7: Finally, the questions were answered, like describe if there was more evaporation rate in the square or circle bowl? Step 8: We described if there was more evaporation rate in the large, medium, or small containers? Step 9: Then, we did two more trials so our data would look more reliable. Step 10: Finally, we concluded my explaining if our hypothesis was correct or incorrect?
