The video on the left is showing laundry detergent pushing water and pepper away from it. Water is polar thus binding with itself, but the detergent is not, so water does not want to go near it, giving the reaction you see here.
For this lab, we used sand as our learning tool to learn about hydrophobic substances. The picture on the left is showing the blue sand which is hydrophobic, or, "water fearing." It's crazy how the water does not mix with the sand at all.
This experiment was working with bubbles. We learned about the chemical makeup and bond movement in a large bubble, made our own bubble solution, and blew some awesome bubbles!
One of the main chemistry skills we learned in this unit was how to draw and identify inter molecular forces. This idea and mixing of elements is the reason that we have three states of matter, and is the reason why elements mix with each other or do not.
Learning Analysis
This chapter built upon the previous chapter. We had to be able to do Lewis Structures with ease and be completely confident in being able to tell if a compound is polar or not. This was surprisingly the case for me. At the end of the previous unit I was still a little bit uncertain in my Lewis Structure drawing abilities, but after finishing this unit I am completely confident in these skill. I am still a little shaky on intermolecular forces, but that is only because I missed the days we learned about what they are and how to find them because I was sick. I really enjoyed learning about the chemical makeup of opioids and the Opioid Crisis because it felt current and relevant, which is one of things I love about the subject of chemistry. Overall this was a great unit with fun experiments.
