Today we did a lab that including the whole class. This lab had to do with sand. We could not get normal beach sand but Andrew brought colored reptile sand which I think made it more fun. This project had to do with polarity, polarity refers to a separation leading to a molecule or its chemical charge. For instance water is magnetic and can dissolve a lot of things such as when water meets salt it dissolves the salt but the salt gets revealed again when the water evaporates. When the water dissolves it the sodium and the chloride separate and merge with the water. Another example that Andrew taught us is how Acetone could take off nail polish which means that nail polish is non polar.
Look Back:
The results for my experiment were very, very good I think, because when we poured the sand into the water it was waterproof. It did not get all soaked up which was really surprising for me because I was skeptical in the beginning just because I could not picture it. The experiment looked like worms in the water it was really cool how it was waterproof.
Looking Beyond:
On a molecular level when the sand was sprayed with silicone it just looked like normal water sprayed but when I touched it, it was really sticky. When we put it inside the water gathered at the bottom of the container and got really chunky and waterproof like.
Looking Inward:
Somethings that I think contributed to desirable results was taking good notes while Andrew was teaching the class. He taught to the class what we needed to know prior to doing the project which I think gave us a really big leap ahead with understanding what actually happens on a molecular level.
Looking Outward:
Although this was a class wide project we did work in groups again. And I worked with Marco and Nayeli it was really easy for us since Andrew taught us everything before.
Looking Forward:
I would not really do anything different to change this project because it was already really easy but maybe I could incorporate this into something else bigger and better.
Take aways:
I took away a lot of wisdom and knowledge from this because before this project I had no idea what polarization was I guess I could teach people about this.
