Evaporation and Wind

SC.2.E.7.3


Investigate, observe and describe how water left in an open container disappears (evaporates), but water in a closed container does not disappear (evaporate).


Evaporation is a type of vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance. The other type of vaporization is boiling, which is characterized by bubbles of saturated vapor forming in the liquid phase.


When water in an open container is heated up the water inside has its molecules move at such a degree that the water changes phases from being a liquid into a gas and without a lid the vaporized water molecules escape into the air. If the container had a lid than the water would be trapped in the container since there would be no place for the water to escape to.

    Investigate that air is all around us and that moving air is wind.



Take a deep breath and then exhale onto your hand. What you just breathed in was air and it is essential for life. What you felt as you blew onto your hand was something called wind and wind is just air that happens to be moving. Wind can range from being a small breeze to a powerful force of nature.

Why are glogs important?

I think that the uses of glogs are very important when it comes to education children. By using these poster messages we can let students know exactly what we want them to learn by feeding them the information. We can also help guide the students be providing helpful links to websites to increase their knowledge on a particular subject. At times it can be very difficult to direct children especially when it comes to learning but by using glogs we can put our own spin on things so as to make things easier to understand. I can definitely see myself using glogs to help educate my students in the future.
