Weekly Blog : Victor N. 8B Image Location Summary Waves carry energy and also carry messages. Signals are created from transmitters which are sent to receivers to receiver and make the message. There are 2 types of signals, digital and analog.  Analog signals record wavelength and the amplitude of the waves. This is to record how much the voice change and to transmit the music. Digital signals are made from analog signals that are continuous and do not terminate. They are also transmitted in digits, 0's and 1's. You can debate on which signal is better than the other. Some can argue that analog signals are better because it records the original information so it must be better. Some can argue that digital signals are better because it's easier to transmit, you can manipulate and edit easier, and there's no undo button for analog signals. In conclusion, there are 2 types of signals, digital and analog. Many argue that digital is better than analog. SP2 - Using...

Music Industry Debate: Digital vs Analog by: Victor N. 8B The format I want to record my music is digital. There are so many upsides in recording music digitally rather recording my music in an analog format. I want to record my music in a digital format because it's so much easier and modern. But, my producer wants to do the opposite and record it in an analog format. To his point of view, I can see that digital has some cons that will be better in an analog format. However, I want to show that there are downsides of analog that are way worse than digital. Recording music digitally has so many upsides. According to the Analogue Vs Digital:Advantages Vs Disadvantages Article , there are many pros and cons in recording in a digital or analog format. With digital, you can edit and manipulate the sounds easier. It's inexpensive, simpler, more space, and can save you lots of time. Yes, there are some downsides to the digital format, such as limitations and reliability. But ther...

Weekly Blog : Victor N. 8B Image Location Summary Energy is split into waves. There are two types of waves, mechanical waves and electromagnetic waves. Electromagnetic waves is light and does not require a medium. When looking at electromagnetic waves, there is a spectrum that it follows: radio waves, microwaves, infrared, invisible light, Ultraviolet (UV), x-rays, and gamma rays. Mechanical waves is sound, and does require a medium. Sound waves are both mechanical waves and longitudinal waves. The medium it requires to travel through are like solids, gases, and liquids. Sound waves travel the fastest in a solid, because the molecules are packed tightly together. Sound waves travel slower but farther in a liquid, because the molecules are touching each other. Sound can't travel through gaps, which slows the wave down. Sound waves travels the slowest in a gas, because the molecules are far apart.  SP2 - Using Models This week, I used models when I was learning more ab...

Weekly Blog : Victor N. 8B Image Location Summary Sound is a vibration of molecules that travels through air. Sound can make you see things differently. For example, one scene can have different background music and sounds, and can change the feeling of the scene.  There are 2 types of sound waves, transverse waves and longitudinal waves. Transverse waves are vibrations that perpendicular to the direction of travel. Examples of transverse waves are water, string, and light waves. Longitudinal waves are vibrations that are parallel to the direction of travel. Examples of longitudinal waves is sound. Waves only transfer energy. To model sound, you can make a sound graph. There are 4 factors in a sound graph: the crest, the trough, amplitude, and wavelength. The crest is highest point of a wave and the trough is the lowest point of a wave. Wavelength, measured in meters, is the full cycle of a wave from 1 point to the next point. Frequency, measured in hertz (Hz) is ...

Roller Coaster Project Blog : Victor N. 8B Summary A roller coaster is a track with an operation, that could be a car or cart. There are different elements into a roller coaster, that includes a hill, turn, and a loop. Roller coaster have certain factors that add thrill to the ride, aka "thrill factors." In this Roller Coaster project, we are to create a roller coaster using tubes, dowels, and tape. The roller coaster can only be inside the 4ftx2ft base, and must have a safe stop. I learned that we need to be precise of where we place the tube. If we don't, the tube might be placed wrong, and that will affect our ride. We learned to fix our mistakes, by modifying and making any changes as needed. The ride ended up working as planned. Backward-Looking:  What problems did you encounter while you were working on this piece? How did you solve them? We had encountered some problems while working on this project. For example, when creating our hills and turns, we d...

Weekly Blog : Victor N. 8B Summary When you look at a roller coaster, what do you notice? There are different elements in a roller coaster, containing at least 1 turn, 1 loop, and 1 hill in every roller coaster. Even though you can't see it, it is there. There is some strategy when building a roller coaster, because you need to know what will make the car move. With strategy, there are some constraints into building a roller coaster. You would need to have the roller coaster on a base, and some support holding the ride. And of course, you cannot have the car stop by falling off the track and landing in a pit hole, you need to have a safe stop, so that your riders are safe. As you can see, the elements of a roller coaster makes it so that there is a "thrill factor" in the ride, and so people will be interested in riding. SP2 - Using Models I used models this week, when we started our new project, The Roller Coaster project. We are to create a roller coaster and...

Weekly Blog : Victor N. 8B Image Location Check out the Kinetic and Potential Energy Song! Summary "Energy in motion is kinetic, energy that's waiting is potential. But whether it's kinetic or potential, both of them are energy." Did you know that the greek word for "in" means "en," and the word "ergon" means work translates to energy? When you put these two together, you get energon / work in, which means energy.  Energy means the ability to work and is split into 2 forms, kinetic and potential.  When you have mass and speed, you have to the ability to do work.  Work is measured in the unit of joules, using the formula Force x Distance = work.  1 joule equals the force of 1 newton acting through a distance of one meter.  Kinetic energy is a scalar quantity and is the energy an object has due to its motion. Kinetic energy can be measured using the formula: 1/2(mass x speed^2).  Potential energy is the energy stored and ...
