Elements (Post #5)

Elements are so cool! They are the base of all matter, and literally are atoms. I find it especially cool that everything that you touch isn’t just made up of one element, it’s many elements combined. I watched the periodic table song, and it’s very catchy. I remember my sister five years ago used to have to memorize the song, so she sang it all the time, and ever since then it was stuck in my head for a very long time. Having it reinforced brings back many memories. The most fascinating thing in my opinion though is that even with so many objects made out of different materials in this world, there are only 118 elements that make up these materials. The coolest though is that if you change one little proton of an atom, it turns into a totally different element. Pretty cool!

Atoms (Post #4)

The idea of atoms is amazing! I find it interesting that atoms make up the whole universe, and that there are many types of atoms. The most shocking idea is that technically everything is almost nothing, because in between the nucleus and the electrons of atoms, there is absolutely nothing. Even our human bodies are made up of just atoms. I also learned that atoms are so incredibly small, so small that the naked eye, or a normal magnifying glass can’t even see them. You would need to get an electron microscope to see it, which magnifies things over 500,000 times, to see little details of an atom. Imagine so many closely packed tiny atoms in the huge universe. There must be trillions of them in the universe! Though the class couldn’t get together in person to talk about Atoms, just watching the videos about it was already cool enough.

How did I use energy this weekend?

I used a lot of energy this weekend. For example, I used the oven’s thermal energy to make some delicious fudgy brownies. This is thermal energy because the brownie’s molecules are vibrating faster due to the oven’s rise in temperature. I also used gravitational energy because as I was playing basketball on my house’s hill, every time I shot the basketball into the hoop, the ball bounced on the floor and started rolling down the hill, which is now motion energy. This is gravitational and motion energy because the ball hit the floor due to gravity, and then starting using that stored energy to roll down the hill, which is now motion energy. Finally, I used elastic energy by pulling a rubber band back and then letting it fly. This is elastic energy because I pulled the rubber band back, creating stored energy when it had a strain on it, and then letting it fly.

What is Energy?

Energy is the ability to do work. Every time your body moves, you’re creating energy. This type of energy is called kinetic energy, or the energy of moving objects. There is also potential energy, or energy that is stored. These are the two main categories of energy. Some types of energy that fall into these categories include Elastic, Thermal, Motion or Mechanical, Chemical, Electrical, and Gravitational.

As I mentioned before, Kinetic Energy is the energy of moving objects. Some types of energy that I listed above that fall into this category are Thermal, Motion, and electrical. Thermal energy is energy that comes from an object whose molecules are vibrating faster because of a rise in temperature, motion energy is energy stored in moving objects, and electrical is energy cause by moving electrical charges. These types of energy are all Kinetic energy because they have vibrating or moving molecules.

Potential energy is energy that is stored. Some types of energy that fall into this category include Elastic, Motion, Chemical, and Gravitational. Elastic energy is energy stored when there is a strain on it, Motion energy is energy stored in moving objects, chemical energy is energy stored in the bonds of chemical compounds, and gravitational energy is energy associated with gravity. All these types of energy fall into the Potential energy category because these types all are storing energy, rather than using it.

In conclusion, there are many types of energy, more than you probably thought.  Each type of energy is probably included in all of our lives, whether we know it or not.

 

Automata #1 (Post #3)

A couple weeks ago, we were given 6 mystery boxes. Our task was to figure out how the stick sticking out from the top of the box was moving like it was when we twisted the stick on the side of the box. The challenge was really difficult, and our table was stumped for a lot of them. When the answers of how they worked were revealed, we didn’t get anything right, but at least we knew how it worked now. When we were instructed to make our own automati, we watched a few videos. Many of the automati displayed seemed very complicated at first, but then Mr.Calvert explained it to us, and the automata seemed quite simple. I was ready to make the very best automati!

Breakout (Post #2)

Breakout

Click! The lock clicked open! In technology, we did a breakout, which is very similar to escape the room. Our challenge was to open a few locks on a box, and the box contained all the safety goggles in the room. Mr. Calvert hid a few clues in the room to help us open the locks. Some of them were in plain sight, but others were more hidden. The clues were hidden in unusual places in the room, and I was surprised that we found some of the more hidden clues. There was also a bonus box with only one lock that wasn’t mandatory to open to win the challenge, but the item inside the bonus box could only help. We were given 25 minutes to open the box with three locks on it.  One of those locks was a direction lock, one of them was a numbers lock, and the other was a letters lock. Our group opened the locks with about 8 minutes left on the clock, and it turns out that we got record time! Our group succeeded because we listened to each other closely, and we didn’t argue a lot. See, teamwork does make a dream work! This challenge was a very enjoyable experience, and I hope to do something just as fun as this again in technology!

Intro to Tech (Post #1)

Three days ago was my first day of technology. One of my teachers from my elementary school is now my technology teacher, and his name is Mr. Calvert. Mr.Calvert talked about the rules of technology, and most of the rules were related to safety. I thought that the rules were fair, like not being able to touch dangerous tools without permission, and not running around in the classroom. I learned that the glue guns can heat to 300 degrees, and that the power sander is the most dangerous tool in the room, because it would just shred your skin off. At first, I thought that wasn’t going to be able to get through technology without having an injury, but then I felt more comfortable when he told our class that it was perfectly possible to get through tech without an injury. Now, Mr.Calvert is teaching us how to blog, and where to find example blogs to guide us through the blogs. I hope that technology is going to be the best quarterly, and I can’t wait to get started on a project(especially the flashlight project)!

Basketball forever

By Justin Zhang

The ball, swoops high in the air, swish! That’s why I love basketball, it is fun and fun to see you and your teammates score points. Basketball is where all the joy is of the great game that started with a physical education teacher not knowing what to do for the kids.

I love playing basketball because you can talk with your friends and it is fun to make baskets and have your friends say yes in their minds. One game we were playing a team that was bad and we dominated like hungry beasts. We scored almost every bucket. Basketball was always there when it was hot just when I always loved to play it and where I improved the most.  I also loved to watch basketball by myself and I loved the Cleveland Cavs. I chanted, Cavs, Cavs, go by myself because I am the only person in my family who likes the team.

Playing basketball brings a joy. You work on your dribbling and mostly on your shooting when you do practice by yourself. (Maybe your dad watches you play.) People usually shoot shots and not drive to the basket. People don’t drive to the basket because it’s much more fun shooting lots of shots instead of going to the rim.
