experiment:
In this experiment our objective was the create sand that was water proof. To do so we took sand, put it in a tub and sprayed serval layers of scotch guard on it. The spray is acting as silicone and making the sand water proof because it is providing a shield. Since the spray we were putting on the sand was non-polar and the sand and water are polar, that is why the sand cannot get wet. Polar and non-polar do not go together.
LOOKING BEYOND: Sand is hydrophilic, if it wasn't, then the ocean wouldn't be able to touch the sand. Things that are able to dissolve in water are hydrophilic because they can stand the water. Things that won't dissolve in water are hydrophobic, it is like they are afraid of water. So considering sand is hydrophilic, we did an experiment and made sand the opposite which is hydrophobic. Since we coated it in silicone and silicone is a non-polar, it didn't want to touch the water.
LOOKING INWARD: I thought this experiment was super interesting. We got to discover a lot of non polar and polar information. We also learned more about ionic compounds which I find really interesting because it is all a lot of information about all these things in our every day lives.
LOOKING OUTWARD: I would say for this that it wasn't an amazing experiment but it was definitely cool. I think the best part was when we poured the water over the sand and just watched the clumps of water roll around. Also dumping the sand in the cup of water was also really weird because it just looked like a sponge. So I think that the outcome was cool and satisfying, but the process wasn't so great.
LOOKING FORWARD: I think with the whole process of learning about covalent compounds and ionic compounds, it has shown me that I really enjoy learning about the really gritty science info. It can get confusing but overall I like to challenge myself and want to start doing more things where I have to learn a lot of science behind it.
TAKE AWAY: I think what I took away from this experiment was my knowledge. Normally I take away I cool image or product, but this time I was satisfied with just the learning. I liked the lesson and am glad we did this and got a lot of help from my peers and teachers to understand.
