Looking back:
In this experiment, we put sand in a petri dish. We then sprayed and mixed scotch guard onto the sand. In order to see if the scotch guard would work, we put 5-6 coats, also dependent on how much sand was in the dish. We then poured water onto the sand to see if it would interact or not (we were hoping for the latter). It worked to some extent. I wouldn't call what we did a success but it also wasn't a failure. It seemed to work pretty well at first but then what happened is the more we touched or moved any of the sand or water around, water would seep into the sand, therefore proving the experiment wasn't as desirable as hoped for.
Looking beyond:
We covered sand in scotch guard (a waterproof substance), in order to see the relationship between polar and non-polar molecules. The scotch guard created a polar film over the sand (a non-polar substance). When a polar object interacts with another non-polar object (water and scotch guard covered sand in this example), they do not interact, like oil and water. In more scientific words, they do not create a solution. This was what we were hoping to achieve with this experiment.
Looking inward:
Our results were not exactly desirable. After learning about polar and non-polar substances, this experiment didn't really affirm any of that information. I don't think that there was anything we could've done differently with the resources we had. If there had to be something we had to change, I would've said to add more scotch guard to maybe get more of a non-polar sheen on the sand. Overall, we did everything as we were taught to do, yet that didn't work out very well.
Looking outward:
I worked with Darcy, Brianna, and Olivia on this lab. I think we worked together pretty well and went through each of the steps thoroughly and correctly. I don't think we could have done anything differently or better during this lab because we completed it to the best of our abilities.
Looking forward:
If I were to do this lab again, I would've used something more dissolvable such as salt. This would make it so you could really see if the scotch guard was working or not because whatever wasn't covered thoroughly would just dissolve. Overall this was a pretty interesting lab that did teach me about non-polar and polar substances, even if it didn't work as planned.
