Water Properties

My water property demo was the water cycle.  For our demonstration we set up an already created water cycle demonstration object that our teachers had nicely lended to us. :) We then put ice in the cloud holder and put a light on it to create condensation.  When it was our turn it did create condensation but did not rain a whole like like we wanted because it needed to sit under the light a ton longer.  And also our light broke when it tipped over but thankfully the ice did condense.

I've learned many different things about water properties.  When Joe and Victoria presented their demonstration in class I learned that fish use buoyancy and salt water makes the water more dense so you are more buoyant.  The more salty it is the more dense and buoyant you will be.  

Also, I learned what a solute and solvent is with Kaitlin and Kendall's demonstration. 1.) A solute is whats dissolved into another substance. 2.) A solvent is a component of the solution in which other substances dissolve, such as water.

When Colton and Mauricio and Mathew did there experiment, we learned that cohesion is grouping of water in one drop, adhesion was when water stuck to different things, and soft water creates more suds with soap than salt water.  It was important to marine life because it's hard for sea grasses to survive in hard water. The water has to be soft, according to them.

This basically summarizes what we learned that day, we learned tons more because their were over 20 people but these are just samples of what we did.

This will help me with my aquarium project because maybe some fish can't survive in salt water because of how buoyant it is or maybe there's certain solutes that can't be mixed in to the water if the fish are able to survive.  The different projects model a real ecosystem in different ways because all of these things are involved in different aquatic lifestyles.
