Water is the most common liquid in the universe. They are also essential for the existence of life as we know it. But what is their shape? We know they adopt the shape of whatever vessel they are in, but when we look at them under conditions of microgravity, we will find out some things we did not know.

In this lesson we will do demonstrations in the classrooms on Earth, concurrent with demonstrations Eytan Stibbe will be doing from the International Space Station to learn about the properties of water, about the intermolecular gravitational pull and about the term surface tension.

A lesson plan is attached to this lesson, which you will be able to distribute in class concurrent with the space broadcast to delve deeper into the subject.

The lesson has been submitted as part of the Learning from Space contest by Maor Madmon. A special thanks to Thea Elad.
