Spanish III is overall a great class. I have learned many vocabularies, develop sentences and etc. This spanish class especially open place where students could participate and talk while learning a language. Some of the benefits I received from taking Spanish is being able to communicate outside of school. I was able to develop basic sentences using vocabulary I learned throughout the year.
While we were coming to an close in unit 2, we had to make a project where we had to make attractions to Georgia and what we recommend.
This is a project where we had to write about a famous writer in Spanish.
In our English Language Arts class, we are working on writing a book with a story that we would like to produce.
Finally when the final quarter of 10th grade comes to an end, we will have to produce the book and public it to amazon. Before doing that, we have to make a trailer of our book.
This is my 10th grade Geometry class and the projects that we completed throughout the year and linked below.
In this presentation, we had to make up two questions that would be relevant for the classmates to answer as a Surrey on google forms. Depending on the responses received, we were required to make two way tables and give brief explanation of the key findings that we found throughout the project.
For this presentation a tortilla or a cookie, ruler, piece of string, butter knife was required in order to complete this project. From the steps provided by the teacher, we had to find the circumference of the cookie or tortilla and record our answers.
In this video game, we had to design a player with an element and oxygen also using a map. And move throughout the map using grids..
In this project, we had to read articles and complete google form based on reflections on the articles in complete sentences and present the thoughts during class.
During AP computer science class, we had to make three parameters for color and also a size function for code. Creating this code was much easy because it was easy to write functions after defining the function.
Recipe for Watalappan:
During our Chemvas lab classes, we had to make our favourite dish. I decided to make one of my traditional food “Watalappan”. It is a dessert typed dish and here is my instruction for creating the menu.
Final slideshow of video/ everything that was required.
This project was to make a story where we use all the elements in all our 10th grade classes.
This is digital art that i made using the art tools that I learned throughout the year in my Art class. I modeled Couple of Air balloons including clouds and a sky.
This is images of our still life photos that we have to take during Art class. The main purpose of this was to present a unique way of an object or objects and take is as a "still life picture"
During the past several weeks in our chemvas class, we were to make a dish that we would like to make with group members. While we were making it, we have required to take still life photos, food photography, menu designs, and everything else that related to Chemvas such as physical or chemical properties etc. And finally creating a final video of our process of making the menu design.

I'm going to build my initial prototype usuing this Configuration.
Since we are Virtual Learning this year our Engineering teacher delivered us a kit which contains all the materials that is needed for our projects throught the semester/year. Our first assignment is to take pictures of our materials and describe them as shown in the picture on the left side.
During class, we learned that automation is the way of how something works.
Our first project is to make a robot through our kit which the teacher provided. So far, we are learning the basics of how to automate it.
This is the plan of how to automate light. Engineers use variety of symbols that are used to make a circuit diagram. Which the symbols also can be used as a common lauguage for the engineers.
As we can see in the picture, for the light to flash, it includes coin battery and wire. The red wire (positive) goes to the bent side of the light and the negative wire (black wire) goes to the other side of the light. When we simulate this is what the circuit picture looks like.
In this robot it has a sensor on the front which can be rotated and the jumpers wires are connected to the Arduino in the middle including while the batteries are on the back. There are also two wheels which holds the projects and helps for it io move.
This robot contains a sensor on the front for it to rotate and measrure the amount the distance of a near object if close. And all of the arduino, batteries, jumper wires and connected to the back of the board. And also it contains two wheels For it to ride.
This simple robot is made out of cardboard which many people use and have lying around their house. . It has a sensor on the front which also indicates for the eyes. All of the parts for instance, the arduino,, jumpers, battery holder are placed inside the card board which ends up having an amazing project.
This is the Circuit picture of how our design looks so far with the arduino
This circuit diagram shows how the wires connect to the Arduino Uno.
This is a short video of my two servos spinning. We still have not coded it to where the two wheels spins in the same direction at the same time. But in the future we will progress through.
On top is the current code that we use for our two servos to spin and work. In the future, we would make the two servos rotate the same direction and also have a distance sensor where it could measure the distance of near objects.
During the past several weeks, In order for the servos to work, We had to connect the bluetooth from the Arduino to the computer. But, we have added 4 battery packs and connected to the breadboard/Arduino. Now, the servos work from the batteries and no need to use USB to connect to the computer anymore.
During this week, we had to plan our path for our robot to traverse to the living room. Here is my direction below starting from the hallway to the living room.
Forward
Right
Right
During the first several weeks, when I upload the code from the computer to the Arduino, it would not update the way it has on the code.
2. The Arduino ran out of power so had to grab a new one.
3. One of the jumper wire cables which is connected to the breadboard had a shortage issue and had to switch a new one.
4. One of the battery packs from the servo had a wire shortage so had to replace.
My robot is in a sandwich form. It includes breadboard, Arduino, blue wire, Jumper wires, two servos to hold up the wheels, and four battery packs. In the breadboard both the black and red wires from the servo goes in the breadboard, GND to Arduino goes in the breadboard, One of the black and the red wires from the first battery goes to breadboard, also the black wire from the battery pack goes to the breadboard. The second wire from the battery pack goes Vin in the Arduino including the two white wires from the two servos.
My robot traverse its path by moving forward for 2.5 seconds, then taking a 180 degree clockwise right turn. It goes forward in a backward position, turns 90 degrees counterclockwise, goes forward for 2 seconds and makes a full right turn, goes forward but has a curve to the left so fixes it by going to the right.
Ultrasound is high-pitched sound waves with frequencies higher than the audible limit of human hearing.
Ultrasonic Distance Sensor can report the range of objects up to 13 feet away.
HC-SR04 Ultrasonic distance sensor consists of two ultrasonic transducers.
It all starts, when a pulse of at least 10 µS (10 microseconds) in duration is applied to the Trigger pin. In response to that the sensor transmits a sonic burst of eight pulses at 40 KHz. This 8-pulse pattern makes the “ultrasonic signature” from the device unique, allowing the receiver to differentiate the transmitted pattern from the ambient ultrasonic noise.
Start by placing the sensor on to your breadboard. Connect VCC pin to the 5V pin on the Arduino and connect GND pin to the Ground pin on the Arduino.
To install it, open the Arduino IDE, go to Sketch > Include Library > Add .ZIP Library, and then select the NewPing ZIP file that you just downloaded.
During class today, my teacher wanted to check our understanding of the code. She gave each individual pseudo code and during class we need to make our robot complete our series of commands. Here is the Pseudo code i was given.
180 degree tank turn to the right
Forward three seconds
Backwards three seconds
90 degree standard turn to the left
Forward for 5 seconds.
For extra credit:
After the above commands get your robot to do a full 360 tank turn to the right and a full tank 360 degree tank turn to the left.
When I first built my robot I had multiple errors. I had a problem where the code did not work when it is not plugged in to the computer. I also had error where my Arduino burnet, jumper wires were out and also one of the battery pack cables did not work. But, thanks to my teacher we were able to out-pass everything.
This is the picture of my first robot which I had multiple errors.
Function: Functions is very helpful the breakdown a lot of blocks of codes rather than having to write multiple lines
 of code.
This is a picture of my sensor connected to the breadboard. This reads the distance nearby and could be very helpful to turn if it is close to a wall.
If/ then statements gives a specific command where tells you to do "If Open Text Button then animate else Nothing" while the Functions on the left indicates to simplify blocks of code into smaller codes of lines which makes it easier to view.. This is a example of If, then, else statements where I used a screen Gui to show the animation when click on the "Text Button" .
Here is a circuit picture of my sensors wiring from Ultra sonic sensor the the Arduino uno. As you can see, I changed the wires different colors so that it would make the viewer easier to see.
If the ultrasonic sensor is wired right to the computer and the the code is right, the sensor should start measuring the distance of the nearby objects by looking the serial monitor on the Arduino software.
This source is a similar software which shows how a Arduino and a sensor is connected to a phone. To make sure the code work, we have to make sure that the pins are the same connected on the Arduino as well as the Code.
From this source I was able to get idea of how to connect ultrasonic sensor to a phone paired by bluetooth. 1.Connecting the ultrasonic sensor. 2.Programming the sensor. 3.Bluetooth module. 4.Programming bluetooth module 5.Testing bluetooth. 6.Combining devices.
After successfully connecting the bluetooth devices, we would be able to control the robot through out phone.
During class, we discussed and took notes about the constraints of our robots. We were able to develop ideas where we could design our robots to look cooler.
This robot is not made from cardboard although it has a sleek design and simplistic in the outside. It has many advanced functions as well but we don't need to focus on that since we are just getting idea of developing our robot. This has all the easy access to all the components in the back of the robot.
This robot is designed in a sandwich form. Although the gadgets aren't the same the finished design of the robot is easily accessible and easy to change.
This robot is cool designed robot. Although we do not have 4 wheels, the robot's design is simplistic and easily accessible to the inside components.. I also love the eyes in the front of the robot. It makes it more cooler.
This is a sketch of my robot where I planned how I will develop the rest of my robot. I made doorways in the front and made hole in top of the cardboard so that I could add a LED lights. The doorways will be also be able to open so that the wires would be able to move throughly.
This is a picture of my back of the robot where I can view al the wires that goes from the battery pack.
This is the left side of my robot, where I also made a doorway for so that it would be easier for the blue cable to connect ot the computer.
This is the main where I added a layer of cardboard on top so that I could see all the wires that is connected to the breadboard and the Arduino uno as well.
This layer is also open and close, to make it look even more nice I added a light.
This is the final video of my robot where I show the robot rolling.
This is the description about my robot in which I explained the internal and exterior design.
This is the cardboard box which we had to make given from the inches.
This project, we build mechanical motions where we learn how something mechanically works on cardboard and the power transmission.
In this image, we see our goals to accomplishing this project and chance to get idea of what questions we view.
In this image, we see our requirements to the finish of the project, and see the constraints.
This is my cardboard automata where I made dinosaur moving in rotational motion. The stick is the linear motion which moves back and forth while the pan in the bottom is the cam.
This is the face which I designed in class. I was getting familiarized with Inkscape so we had to design a one piece shape.
This is a screenshot of the gear I designed for my Engineering class. I first used to image the teacher provided and added the image to Inkscape and resized it to the size I want. Then I created a circle and placed it to the middle of the circle by using "Align and distribute". After, I selected the middle circle and the gear by using shift and made a hole by using "difference". I made small but long rectangular shapes for my design. I added as many as I want and finalized by using 4 long rectangular shapes by duplicating the shapes. I used the "Align and distribute" again to get to the middle of the circle. Then, I grouped all the rectangles. I added a circle in the middle, sized it and selected both the circle and the grouped rectangle and made difference. For the finalization, I grouped all the objects in Inkscape and grouped them all.
Upload gear provided by teacher.
Make circle with ctrl.
Get it in the middle of the gear by using the "align and distribute" tool.
Add a unique shape with ctrl and adjust to properties in the top left corner after click.
click the middle circle of the gear and click path and "object to path".
Take the fill of the circle out by clicking 'x' on the right properties
Click on "stoke pain" and increase the outline thickness so that it is visible to see.
Click on the circle, path, and "path effects".
Click on the "+" in path effects and search for "pattern along path".
Copy the unique object and pase it next to the paste side in the pattern along path. And you will see your unique shape.
Change the properties to a property you like.
Click on the unique shape three times and click the grab icon and can adjust the shape to whatever you like.
After you are satisfied with the object, click on the gear and the unique object inside the gear using select and click path and group them.
Two of the gears spins the same rotation.
The drive gear spins 1/2 the speed as the gear in the middle.
As seen in the picture above, this is the gear simulation which we had to make to a linear and a rotational motion. The fidget spinner looking gear has a slot for it to move in linear motion from the friction.
In this structure, we see that the motor is spinning the cams and spinning in a rotational motion which makes the tricam move in a linear motion in it's specific slot. Engaging with the motor cam, the tricam with it's friction rubs along to move in a linear motion (up and down).
When turning the drive gear from the shaft, it spins all of the child gears to rotational motions. The drive gear has all of the three layers, based on the picture it is going to engage with two gears and spin so that they rest of the gears would spin in rotational motion. In the video, the big circle has two layers of the same gears which makes it spin in opposite directions.
Today we were required to plan our final project using items in our kit. First we had to decide what direction we are going. I decided to make an opposing.
This sculpture looks similar to our teacher's one. It has two different layers and spins in rotational motion. One of the gears spins left while the other layer spins right.
This one also has two layers with cool patters and spins at the in rotational motion when motor turns on.
This gear spins rotationally according to the wind. when the wind pushes it, it spins in rotational motion.
In this project, we had to spin our gears using a motor and ultrasonic sensor. When the distance is close to the distance written in the code, the motor will spin which will also spin the gears. Also, when the distance is read less, it will stop spinning.
In these engineering projects, it is very beneficial in the future because we have to make our own gears through software that we learned throughout this year and then 3-D printing it so that we could use it in real life. By these, we were also able to solve problems and thinking during the design of the process.
This project took almost the entire 2nd semester. We first had to cut cardboards to represent our acrylic and basic gears provided to get the idea of how the gears spin. After, we were using 3-D software (Inkscape) to design our gears. The teacher printed our gears and acrylic and we had to assemble them in a way that we picked (linear or opposite motion). Next, we had to make a circuit with an ultrasonic sensor (which reads the distance) and also a motor. The ultrasonic sensor reads the distance if an object is close and then the motor would spin accordingly. If the distance gets further apart, the gear would stop spinning.
This is the arcrylic of my gear layout. There are two arcrylic's the front and the back. And each has holes for the gears to fit perfectly and to rotate in motions smoothly. And finally, placed ultrosonic sensor near free spot of the arcrylic that each time I get close to the design, It will turn on the motor and rotate in motions. However, when my distance is less, it will turn off and stop rotating in motions.
This is the final file for my teacher to print. I have 5 gears in total which means that I will need 24 spacers in total (4 for each gear). And woodsheets on the left side is the wood sheets in which the teacher can print them as wood files.

This are my 3-D printed gears and spinning by the hand-crank.
The goal is for the gears to spin smoothly using the handcrank and for the gears to spin in opposite motion. By spinning in opposite motion, it gave a cool allusion for the gear.
In this, I was spinning the hand-crank and by the rotation of the drive gear, all the child gears under this acrylic spun in clockwise and counterclockwise motions.
This is my ultrasonic sensor and my motor working with the distance. When the distance is closer, the motor will spin faster. For example, my motor spins the fastest when an object is at 2 inches near the ultrasonic sensor. However, as the objects moves further away from the sensor, it will start to spin slowly and eventually will come to a stop when it does not detect distance near. With this, I am able to spin the gears without my manually spinning the hand-crank and also the gears will spin faster and slower depending on how close the object is near to the distance sensor.
Kinetic art is a three-dimensional sculpture work that has motion and expands into the world of The Art and Science of Wind Propelled Sculptures.
In our project, this effects technology by getting the ultrasonic sensor to work and also the motor. In order for the gears to 3-D print we also need software technology which were a very big key role. The coding throughout this process also can be an example of technology that were used throughout this semester.
Engineering is the key to all the sculptures and almost in everything that we use and touch has an engineering design process to it. In this kinetic sculpture, the engineering of this is the design process. For instance, how the gears and spinning opposite or linear motions. Or how we are spacing the gears in order for it to work and spin smoothly.
The Art in this engineering project was the design of the final sculpture. For example, the design of each of the gears has a different art in it. They all have different shapes and a unique way of spinning when they are spun by hand crank. Especially when looking at opposite motion gears it creates a cool illusion and attracts the person.
The math of this final engineering sculpture is the proportion of the gears. For instance how distances apart should the gears be to touch in order to spin smoothly. Another example is if the sculpture were chosen to be desk-mounted, then what would be the proportions of the acrylic that would be needed in order to fit the two layers of acrylic and the desk itself.
Since this year was covid, during the entire year of 10th grade for me, there were some challenging parts for me including not being able to get help all the time in person. But at the end, I am proud of being able to experience an entire year virtually so that I can explain the future the experience of having virtual school at school. I also learned and got plenty of information for the cool engineering designs as well.
