This week, I did some coding in Scratch. I also finished a violin homework book (yay) and got a new one! I also kept learning my Calculus on Khan Academy. I kept going with my taekwondo, violin, and swimming! I also went to nature school on Wednesday.
This week, I completed my violin homework book! And, of course, I get a new one 😛 I kept watching the Essence of Calculus videos, just for fun. I did some EMF (Finally!), this was about adding and subtracting decimals. I did some Brilliant every day of the week. This was about a letter puzzle, and you have to follow the two rules to assemble the puzzle and answer the question “What is the blank space in every solution?” I started to learn the proof of why the derivative of sin(x) is cos(x). I started the electrical engineering course on Khan Academy (yay). I started the “intermediate” section in calculus on Khan Academy. I finished “Derivatives: definition and basic rules” and now I’m moving on to “Derivatives: chain rule and other advanced topics.” I was researching “how to make a good video game” online, and the websites said that you first need a good programming software, and many of them recommended Unity! I haven’t tried it yet, but I will next week. My friend had a birthday party, so I made him this math-themed card! Hehe… After that, I got interested in fractal geometry and found this video by 3Blue1Brown (a YouTube channel) about fractal geometry. I also learned about space filling curves on Wikipedia. A space filling curve is a 1D shape that, if you repeat it over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over again, it starts to fill up 2D space! I watched this video by Matt Parker about the formula for the perimeter of an ellipse. He is the guy who wrote this book! I was watching that video about fractal curves, and I found this, as this was a related topic, and was shown next to that video. I started to learn about vector fields, and how they can model population growth (as shown here). I FINALLY taught my mom about derivatives. And I told her about the product rule and the proof of it. The full proof is too long to be drawn on the chalkboard, so I explained it on my notebook, as shown below. I made an animation for my Scratch projects, just to go at the very beginning of every simulation and game I make. See it here: https://scratch.mit.edu/projects/481039518/ I made my own instant noodles for lunch! I did my violin homework (in the new book, YAY)! The following written by Ethan’s teacher, Mink from Soaring Eagle Nature School: Excited to be out in the beautiful softly falling snow, Mink’s group made their way to a nearby site named Gargoyle’s Garden for their morning shenanigans. Here we played a fast paced warm up game of shrew ball! Over snack, Mink told the story of when her bow drill chord broke just when she needed it most—when her partner on a survival trip was showing early signs of hypothermia. Yikes! Whether you’re going full-survival or just out for a day hike, it’s very wise to come prepared for anything, which is why we spent our afternoon making home made fire-starters. We filled egg cartons with dryer lint and melted wax to create compact fire starters that last a good long time and could make the difference trying to start a fire from wet wood or in a pinch! Everyone got to take a few of these home. Be sure to put them in plastic baggies! While we waited for the wax to melt we played several very fun rounds of werewolf, in which different students got to try narrating the story-line! I’m fresh out of wax but If your child is excited to make more firestarters, send them to program next week with spare tea lights or the remains of old, used up candles and we can repurpose them!
