What is science all about?

Science is all about guessing what will happen, then testing to see if you’re right. You now know that hot water freezes faster than cold water, so brainstorm a new project that you’re interested in. By constantly changing your experiments, you’ll continue learning new things—and become a science whiz!

Does hot water evaporate faster than cold water?
