Explain how it works/doesn’t work using scientific terminology:

This circuit of a solar-powered phone case (or charger) does work because the energy of the sun is received from the solar panel which connects the energy to the battery packs supplying additional voltage. The voltage is enough to power the device because it connects to the breadboard which has a USB port for the phone charger. The charger then connects to the phone. However, at the end of the project, I realized the circuit was working because the breadboard was really hot, and so were the battery packs. Although, something in the circuit kept shorting out because the phone wasn’t charged. As for the circuit, the positive and negative strategy works well with this circuit because of the positive leads connect to negative leads creating a more efficient and effective way of energy transfer.

Explain the areas you were successful in the product/process:

I was successful in making sure the circuit worked, and that energy was transferring. In my first prototype, I didn’t have the battery packs and the breadboard for the USB port because I thought the amount of energy from the solar panel would be enough to charge the phone. However, I found out that my phone only receives a precise amount of voltage. Therefore, additional energy was supplemented from the battery packs. This made us use the breadboard for the USB cable because it was easier using the board than striping the wires.

Explain the areas you need to improve in the product/process:

The circuit was working because the breadboard was hot and I used the voltage meter to make sure the circuit was giving my phone at least five volts. Due to time constraints, I was able to finish and figure out what part of the circuit was shorting out. I tried switching out the batteries, and I double checked my model, so the circuit was matching it. If I could do this project better, I would probably improve on the materials put into the phone case. The circuit is quite large and heavy. Therefore, it may be hard to carry it around on a case. As for the circulation of energy, I wish I knew what was shorting out, but most of the parts of the circuit were working because I felt the heat of each part of the circuit.

Explain the impact of this project on the environment and potential client/consumer:

The effect of this project on the environment and potential clients is that this phone case is very convenient and easily accessible. During the day, you might use up all the battery in your phone, and you desperately need a charger, but you can’t find a port. As long as there is sunlight in the day (and there usually is), it would be very convenient for the phone to be left in the sun for a while or you can use the phone in the sun and still get battery. For customers, it is easily accessible, and for the environment, the phone is using energy from the natural sunlight to charge the phone. This is very beneficial to the environment because it uses energy from the natural sunlight and not electricity.




Blogpost #3: Create and Improve

Reflect on how the process is going:

At first, I had a problem with productivity in the process because of not having the iPhone charger but during the second class, I was really efficient and striped and soldered the wires of the charger to the solar panel’s wires. However, between the second and the third class, I had to find a diode which seemed impossible. My phone could only charge at 2.4A at 5V. When I used the voltage meter during class, it tested that the solar panel gives up to 3 volts. I wouldn’t want my phone to explode which is why I needed to find a voltage regulator. Nevertheless, I came up with a solution. I came up with a more complicated model which worked. The solar panel connects to the diode which regulates the amount of energy let into my phone. Then, the batteries connect to the USB port which connects to charge my phone. However, when I tested this model I knew the circuit was working because I touched the breadboard and it was hot. Although, there was definitely something shorting out because the phone didn’t get charged.

Gather feedback from others (warm and cool feedback):

Karen: I like your design, this could make charging easier for everyone because whenever and wherever you are in the day, it’s really convenient to use solar power for battery. Although, the second model that I’m seeing looks a little heavy because it carries a battery pack, breadboard, the diode, and the solar panel. Is there any way we could still keep the circuit without it having so many materials?

Esther: Your design is very original and I like the idea but how would you put on the solar panel and make it easily accessible when wanting to charge your phone?

Blogpost #1 Define and Inquire: Science 9 Engineering Challenge


This engineering task is about either creating a toy that converts energy, make a renewable energy source that converts into electrical energy, forming a device that transfers energy and makes a tool that can be used to learn physics. Through creating and refining these options, we can produce something beneficial to our community as well.

I have not entirely decided on my idea yet, but I’m navigating myself in the direction of designing and creating a device that transfers energy. One of my thoughts is developing a solar-powered phone case.

The pros of the solar-powered phone case would be more original, beneficial to people, makes a change in society and creative whereas, the light bulb from the battery is used very often and it is harder to make it original. The cons of the solar-powered phone case are that it would be a challenge to develop a phone case. Many uncertainties would make the phone case inconvenient. However, it is a challenge that I could try to overcome in five science classes.

Swimming Unit


In this swimming unit, I was given the choice of choosing what skill in swimming I wanted to improve in. After, I planned drills that would help me achieve my goal. The first picture is a photo of me swimming freestyle in the first lesson and the second picture is a photo of me swimming in the 12th lesson which is the last lesson. My chosen SMART goal that I made at the beginning of this unit is to efficiently use turning underwater to become faster while switching strokes. I chose to do this because I feel it is a quick way of switching strokes when swimming more than 25 meters. A SMART goal is a specific, measurable, attainable, relevant and time-based goal.

I feel that I’ve improved my freestyle by pulling closer to my body and using more strength. You can see that my pull is closer to my body in the second picture. My head is also tilted more downwards in the second picture than the first. It is important to put your head down because if your head is faced upwards more it will help lead the body to stand up in the water. I’ve also improved my speed. The coaches timed my freestyle (50 meters) 6 times and my fastest time in the beginning of the unit was 42 seconds. At the end of the unit, we timed our 50 meters 6 times again and my fastest time was 38 seconds. Which indicates that I’ve improved because my SMART goal was about becoming faster in swimming 50 meters. The biggest change was definitely speed because I’ve improved by 4 seconds. Pulling closer to my body and strength training really helped me achieve my goal. Tumble Turning under water also helped me transition faster. Tucking in my chin and staying close to my legs was what helped me efficiently turn under water. Turning definitely improved my speed.

As I’ve mentioned before, I did a HIIT session at the beginning of the unit to time my 50-meter swim 6 times. I rest 30 seconds between each time to make sure I don’t get too tired. FITT stands for frequency, intensity, time and type. This helped me plan how I want to time my 50-meter swim. HIIT helped me plan my swimming sessions and what I wanted to do specifically on that swimming day. If I were to continue doing this unit I would absolutely use turning to improve my time for 50-meter backstroke. Overall, my 12 lessons in the swimming pool really helped me improve my time in freestyle. Turning improved my speed a lot and I wouldn’t have gotten to where I am now without the help of Ms. Hamada and the ISB Swim Team coaches. The FITT session helped me measure where I wanted to get to and doing cardio and strength training on land help me use my strength in swimming which improved my swimming speed. This has been a great unit and I feel that I’ve really stepped up and stuck to the hard work I wanted to do.

Grade 8 Mentoring Trip


Our trip this year was unforgettable, the best thing about this experience was getting to know my classmates better. Throughout the trip, we went rafting and we also tried the Via Ferrata. The obstacle course was pretty life-changing for me, throughout the two hours we spent climbing we all supported each other non-stop and that’s what really helped us get through the end of the Via Ferrata. The rafting was great as well, we all communicated to build our rafts, some successful some not but everyone still had fun with or without falling into the water. We really did a good job of getting through all these activities together as a whole. We definitely demonstrated some of the core values of ISB such as communication, collaboration, and leadership. This was a great way to start off a school year!




Oneday 2017- Volleyball serving pointers


On Oneday, Ireland, Emmi and I created a video of us giving pointers on volleyball serving. I also learned the pointers of volleyball serving, when I serve now my balls are harder and more successful. Our challenges were when we were filming our serves, it was really hard for us to find the right shot because we would make mistakes or make the serves to short or forget to film an important pointer. My impact was to give pointers to people who want to serve better in volleyball. I will continue on giving people pointers on serving for volleyball when they are struggling. I will continue with the pointers I got from teachers and the video.




One Day Blog Post


Our one-day project was to create a tutorial for badminton. Yesterday we spent our school day playing badminton and making a tutorial video which we are all passionate about. We hoped that watching this video people will learn the different techniques. During this period of time we also learned a lot of new techniques from our peers and mentors.
At first it took us a while to find the a good location and our equipments but even though we started late we completed our  goal on time. We also had a lot of fun doing our project. It was a really good full day fitness exercise for us all.

Judicial Branch


Today we added a judge to our village! Harry is our winner but if he dies then Eileen takes over. We also have a Legislative branch which Nathan, Bernard, Smriti, and Christina are in. Whats happening around are village is that I have build a farm so I can eat bread. We have a Town Hall and it has everything we need and need to do. I build a Basement and a Balcony for a better and fancier house for us to live in. Judicial Branch is a person who judge on things like if someone breaks the law the person could sent him to jail. Legislative Branch is people who makes laws.



Common Good


For common good I’m helping my friend Christina collect wood and we are making bread for our community.
