Hour of Code

During class we were assigned to lear how to use codes to control what happened on our computer screens We were given the option to use either a "Frozen" themed template or and "Angry Birds" template. I chose Frozen, and got to make Elsa and Ana move the way I wanted to with the help of the Hour of Code steps. I really enjoyed this because I got to see how some of the electronic things I use everyday were programed to do their jobs. Something that was challenging was trying to figure out how many degrees the figure was supposed to turn to make the desired shape. I learned how to make simple commands on a computer and make something interact using those same commands. Something that was surprising was the fact that I eventually made around 36 different codes when playing a simple game! One code I used to make a cool shape that looks like a snowflake is listed below, followed by the finished product!

for (var count2 = 0; count2 < 10; count2++) {
  for (var count = 0; count < 4; count++) {
    moveForward(100);
    turnRight(90);
  }
  turnRight(36);
}
This assignment was very fun and a great learning opportunity!

GeomeTREE (octahedron)

A polyhedron is a solid shape with 6 plane sides. The way a polyhedron and a polygon are related, is that a polygon is made up of 3 or more sides, all connected at the endpoints with congruent vertices. A polyhedron is made of 6 or more polygons. For our geomeTREE, I made an octahedron. The shape consists of 8 triangles in 2 groups of 4 triangles each. These four triangles were formed into a pyramid shape and placed base to base with the other group of 4, also formed into a pyramid. The color palate in this shape included dark blue, light yellow, rose red, and dark green. The vertices of the ornament were where each triangle made a point with the others, bound by tape. all of the sides were intersected where the different triangles met. None of the planes were parallel; however, I found the triangles to form pyramids.

Reflection:
I worked on my own for this assignment and spent a class period and a half cutting the triangles out and trying to figure out how everything would fit, and then an additional 30 minutes of finally making the little polygons into the octahedron! I learned what a polyhedron was, and that the octahedron was not made out of octagons, but rather 8 triangles. I was challenged by the actual forming of the octahedron and how the triangles could make a 3 dimensional shape. I really enjoyed the in class time, cutting the triangles out of colorful paper, listening to the Frozen soundtrack, and talking with friends while working. If I had anything to change, it would be to make the shapes due before out test and before the weekend, though my class was the only group that faced this problem.
