Looking Back:
In this lab we mixed water and sodium silicate and then added calcium chloride. This was an interesting lab because we got to watch rock grow. It was cool to see something that happens in the earth, happen in a test tube.
Looking Beyond:
When we added the calcium chloride to the water and sodium silicate solution, metal salts react with the sodium silicate to form the rocks. This is one of the methods to make rocks. We have to do it this way because even though we can get the heat needed, we cannot get the pressure required. This process is done underneath the earth's crust where the environment is correct.
Looking Inward:
This was a lab that I really liked. It felt like less of a participation experiment and more of an observation experiment. I found myself just staring at rocks and how they grew. It was like time was slowing down, yet within the blink of an eye the formation was different. It was beautiful and calming, like watching a sunrise slowly paint the sky.
Looking Outward:
I liked my group for this lab. We always work really well together and always have fun while working. During this experiment it kind of felt like they were being impatient with how slow it was forming. I like how we are all different. It's like we balance each other out. A bunch of different personalities with a hint of crazy in each.
Takeaways:
One thing that I can take away from this is that you cannot get sodium silicate on your skin. Sodium silicate is used in concrete sealer, so it does the same thing to your skin.
