Water, Water, Everywhere
In science class with Ms. Baugher, the 4th grade has been learning about the water cycle. Water is one of the most abundant substances and earth and is vital to survival but what exactly is water and what makes it change?
In KIDLAB, students looked at water on the molecular level. We discussed that all things are made out of atoms and when atoms combine, they make molecules. Water is a molecule consisting of two atoms of hydrogen and one atom of oxygen, hence H2O. Sometimes molecules of water are close together and form a solid (ice) while sometimes they are far away from each other and are a gas (water vapor). Water as a liquid has molecular movement in the middle with molecules not super close together but far enough away from each other that they can slide past. It is for this reason that liquids can pour and move while solids keep their shape. Check out the projects we created to keep these ideas fresh in our minds!
