An exploration of water

In this water exercise, each of the members at our table used different materials to manipulate with water. For example, some of us chose to work with salt. When you added the water to the beaker, it mixed with the salt creating an opaque appearance. However, when you let the mixture sit for a few seconds the salt travels to the bottom. Once the salt is at the bottom, you can see it is starting to disintegrate and become thinner. Before you add water, the salt particles were thick and solid and after the water was added, the salt becomes thin and flaky, almost dissolving completely.  It is important to mention what happens to the surface tension of water when salt is applied.  Some of the tension was temporarily broken when the salt was poured in, but it was quickly re-established.  This is evidence of hydrogen bonds being relatively weak, temporary, and easily broken.

The salt divides up into positively and negatively charged ions that exist independently from the solution. The salt and water creates a solvent solution, the water being the solvent and the salt being the solute. Moreover, as more time goes by, the water at the top of the beaker starts to become clearer.

After finishing this lab, we were able to understand how different things can mix with water and become something else. The fact that we needed to make the solutions ourselves allowed us to see step by step how water changes the texture and properties of things that we put in it. This lab helped us see the different properties of water that we discussed in lab. We all experienced different outcomes with the water during this lab. Collectively we realized the different characteristics of water and how we can easily recreate nature in a controlled environment.

This lab helped us understand the lectures on water, in this lab we were able to see the different properties of water and how water reacts to certain substances in real life instead of just reading about these concepts in a text book. Going back to our subject on patterns, we are able to define the natural process of water in molding and adapting itself the different environmental conditions. By combining the clay and salt into the beakers we were able to observe the different techniques which water can adapt itself to the different materials added.
