I extremely enjoyed this video. Alan Watts has successfully put into words what I have pondered and realized since childhood. The subject of life having any meaning at all is one of the only things I truly have a desire for. The video focuses on the standard of the average human: to continue on living. To live and to survive is our "duty". Our instincts all point to go on living, that we must. And, to the average person, that is all they need. No further investigation is required. The people that accept live as is are usually more shallow thinkers, they don't dig deep into the everyday things that happen. But I am the exact opposite, in fact from a young age I have wondered why we so desperately try to stay alive. This thing we call life should not be viewed as work or survival. There's an unrealistic fear of death that exists in everyone, and you must obey it. But when you're dead, you've got nothing to worry about... you're ok. So life, as we know it, should not be viewed as some kind of job or necessity, but as play. Life is truly, play.

This video focused on how people are more than just things in our way of everyday life. We go about our lives not realizing the everyday things around us, like water. Stopping for a second in our everyday life and realize that a chunk of our stress and opinion on everything around us is a choice. If you choose to look positively on your everyday life, you might realize that some may have much worse lives than you. Its up to you to view life positively. In conclusion, I really wish everyone in the world could see this video. So many people go about their day and don't ever stop to think about what is around them. I think this video could be a great wake-up call to everyone. Now more than ever, the world needs to reflect on what is really happening. Notes - The earth is many layers on top of each other - Lots of heat and pressure in the center - Electronegativity Guided activity: Earth Science - Making Rocks Silicates: Combination of silicon(s;) and oxygen(o) 95% of earths crust and 97% of the earths mantle is made of silicates. Earth 1.Core: made of iron and nickel 2.Outer Core: Made of liquid iron and nickel. 3.Mantle: Made of molten rocks (silicates) 4.Crust: Outer is solidified mantle Na2 SiO3 : Sodium silicate Calcium Sodium Sodium Calcium Chloride Silicate Chloride Silicate Ca Cl2 + Na2 SiO3 --> 2 NaCl + Ca SiO3 Sodium is further apart than calcium meaning it is more reactive. Will KCl + ZnO React? No. Furthest chemicals have the most reaction and will kick any others out or not react at all. What Happened: After all of our equipment and materials were ready, Andrew mixed in distilled water with a strong chemical that would help a lot with the experiment. We needed distilled water because it contains zero salts. We needed a clean additive, and then our mixture of 1.5/1 was mixed in a beaker and distributed into multiple test tubes. We were then ready to proceed. Details: We first put calcium chloride into a test tube, and the reaction was fairly quick. It immediately started to slowly climb to the top of the test tube. Next was cobalt chloride, and it wasn't long before this one changed into purple and blueish colors. This substance also shot its way to the top of the tube. Finally was copper chloride, and this substance seemed to be lazy. It had very little movements towards the top. It was very slow to react, meaning it was closer than the rest to our clear liquid on the periodic table than the rest. Moving forward: What's next?
I enjoyed this experiment in particular, I think it would be fun to learn about different substances on the periodic table and see which ones are more reactive than the others. There's a whole world of chemistry that we haven't explored yet. Looking Back: What happened? Phillippe and I were finally able to launch our rocket, with fantastic success. Because many of our rocket motors exploded on ignition, we needed to use an E-Match, an electric match that at the press of a button flares up to light anything combustable next to it. Our rocket hit a "high" of around 2900g of thrust! This means our rocket body we build can be much bigger than most, because of the thrust at launch is enough to get a bigger rocket in the air.. Looking Beyond: What do you think has happened? What’s the science? From what I can tell, the science behind our rocket launches would be combustion, pressure, and thrust. First, the E-match lights the end of either an end burner or core burner, and the combustable material lights up and starts to create great pressure. As it burns, because the energy has no where to go, it exits the end of the motor giving it energy to fly in the opposite direction of the energy release if it is able to (without a scale in the way). Looking outward: Collaboration and Impact I think my partner and I did really well coming up with a rough draft and getting our rocket labeled with the right statistics for fuel and core details. One thing I would improve on would have been to ask more details of how each motor is made, as we are not old enough to create our own. Looking Forward: What next? The next time we come to Andrew's for chemistry, it will be to build our final rocket body and motor from scratch, combining each of the rocket sections into one launch. Take aways: What I took away from this motor launch is the seriousness of safety when it comes to motors of this size. At first, I didn't think much of them. But when I saw the power of them exploding my opinion changed. It makes sense why they have so much power, because of the amount of fuel to surface area we added. These motors should not be used lightly. Thrust Curve: Interpretation + Choosing a Motor:
I liked our thrust curve a lot. We have plenty of power and for a fair amount of time. At first, because our motor was cored, Andrew and the rest of us were thinking it would explode. However we were pleasantly surprised, as our rocket gave out the most thrust in the whole class, allowing our rocket body build to be full of possibilities and have less limits compared to another rocket with half the thrust. We want to choose our motor because our thrust curve looked the best to Phillippe and I. |
