Science Fair Topics: Evaporation

Decent Essays

My science fair topic is Evaporation. I chose Evaporation because we talk about evaporation but most of us don't see it often at all. Evaporation is an interesting topic and and a piece of matter people don’t really put their interest in. Evaporation happens the Water cycle. An ocean like the pacific evaporates into the clouds, condensates, and precipitates. It happens over and over again. I bet that people put their drinks out and never cover it before going to sleep and a few hours later, It has evaporated. science fair question is How can the type of clear liquid affect the rate of evaporation?

An independent variable is an item in your project that you will be changing. It can the main part of your project and can be found in a question. The liquids …show more content…

It's on the last part of your question. The rate of evaporation is whats changing. When a liquid sits in one place and its molecules turn into a gas, Then it's called evaporation. No matter how cold or hot it is, it can still evaporate. When matter has a high energy then the water molecules have a high energy too and go through a change. Evaporation focuses on individual molecules and not on the amount of energy. The energy can be low and still evaporate. Not all liquids are the same. There are some that evaporate faster in wind. When liquid molecules move around, They bump into each other. When they do bump into each other then one molecule gains energy and one loses energy. If one molecule gains enough energy then the molecule can turn into a gas. In other words, it has evaporated.
Independent Variables and Dependent Variables have a cause and effect relationship can be found in any science fair project(Problem, Hypothesis) such as, Riley's Science Fair Project. If Riley egg dropped in bubble wrap(Cause), then it will break less(Effect) than eggs wrapped in other materials because bubble wrap adds more support. Here is Riley's Science Fair
