Making Masks At Home
By Frederick Ernst
Due to the coronavirus, it can be difficult to find masks in stores or on-line. CDC recommends the wearing of a mask when outside the home and when it’s difficult to remain 6 ft away from others in order to contain the microdroplets that can potentially carry the coronavirus. It’s important that we not buy and hoard the N95 masks that medical workers need right now. However, the City of Los Angeles has issued a requirement that all residents should wear a mask when outside the home, particularly when inside stores or other facilities. Luckily, you can create your own mask at home. Here are some various ways to do so.
One way to create a face mask is to make it out of a t-shirt. For this mask you will need a shirt made of tightly knit cotton material and 2 rubber bands or hair ties. In order to make this mask, first, cut off the bottom seven to eight inches off the t-shirt so you have a strip of material, lay it flat and turn it 90 degrees so what used to be the hem of the shirt which is usually double stitched, is facing left or right. Then, fold the top of the strip to the middle, and fold the bottom of the strip to the middle and repeat one more time. Loop one rubber band over each side (left and right) so it looks like a candy wrapper. Then fold the excess material on the right and left to the middle. Put a band over each ear, making sure the material fits snuggly on your face. Watch the tutorial here:
Another way to make a mask is to use a bandanna and a coffee filter. For this way of making a mask, you will need a bandanna, coffee filter, and 2 rubber bands. To make this mask, fold the bandanna in half. Fold the filter horizontally in half. Take the wider section of the filter and place it in the middle of the bandanna, and then fold the top and bottom of the bandanna. Repeat folding the top and bottom one more time. Loop a rubber band or a hair tie on the bandanna at the left and right side and then fold the parts of the bandanna over the rubber band that stick off over the band. Then, put one band over each ear. Watch the tutorial to see how:
One more way to create a face mask is to sew one. For this face mask, you will need 2 ten by six inch rectangles made from tightly woven cotton fabric, 2 six inch pieces of elastic or rubber bands, cloth strips, string, hair ties. You also will require a sewing machine, a needle, and thread. To assemble this mask, first, stack the two pieces of cotton fabric on top of each other, and then fold the longer 10 inch sides a quarter inch down and sew them together. Then, fold the shorter 6-inch side a half inch down and sew at the edge leaving a small space to loop the elastic in. Thread the elastic in the opening you made. Then tie the ends together. Tuck the knots into the opening. Then, gather the short sides together and sew the elastic into place, as shown below.

I’m sure there are many of us who read about what’s happening in the news and see how hard healthcare and frontline workers are working to keep us safe, and we wonder, “What can I do to help?” Well, 8th grader Zyg Ramsay went ahead and decided to do something about it. He saw the challenges that healthcare workers were having getting all the Personal Protective Equipment, or PPE, they needed. With a highly contagious virus like SARS-CoV-2, doctors, nurses and others must have not only masks and full gowns, but also face shields to prevent the microdroplets that could carry the virus from coming in contact with their faces. Zyg saw that Budmen Industries was looking for volunteers to help flatten the curve and protect healthcare workers by using their home 3D printers to print these face shields.
As he explains, “I was fiddling around on the internet and found the Budmen website that contains 3D printing files. You register to become a producer. They didn’t tell me what to do so I just printed one to see how it worked. I thought, “Once they email me to start printing stuff I will.” I got an email from Budmen saying there was an L.A. location, with somebody putting it together in the L.A. area, so I signed up for that. I didn’t have to design the file; you don’t code the printer’s movements, there’s a program that takes a 3D image and converts it into text which the printer follows.”
MS KINCAID: What material do you use to print the face shields?
ZYG: I use PLA [polylactic acid] for the face shields, which is a plastic made from corn, so it is biodegradable. My printer melts it at 200⁰ C and prints each of the 30 layers layer by layer, printing a complete face shield in 2 hours. There are two things I print for it. One is the actual shield in front of the face, and the other is the strap lock that keeps the elastic in place.
MS KINCAID: About much does it cost to make each one?
ZYG: I calculated it at one point, I think it’s around 12¢ of material for each one. I’ve printed 59 shields, so almost 3 kg of plastic.
I asked Zyg how he got into 3D printing. “About 2 years ago, I read about 3D printing in MAKE: magazine. My first printer cost around $200, but it was only able to print up to 4 cubic inches. I got a larger one for Christmas that can print up to 11 cubic inches.”
Our interview continued:
MS KINCAID: What else are you working on?
ZYG: Right now I’m working on making two drones. One is a tricopter with three propellers and servo motors to turn the propellers. From what I have read, it’s is much more stable and easier to control, but for some reason it’s less common than the quadcopter, the normal drone with a
MS KINCAID: Why do you think that the tricopter is better than the quadcopter?
ZYG: The tricopter doesn’t turn by slowing down one propeller and speeding another like the quadcopter, it turns the servo. It also doesn’t lean when it moves to the side, it stays in place, which helps people with cameras on their drones.
I’m also working on a minor soldering project. My mom bought a PCB for me, which is a superthin circuit board, and I solder super tiny electronic pieces onto the PCB with solder, which is just super easy-to-melt metal that conducts electricity.
MS KINCAID: Are you just experimenting to see if you can solder that small or are you actually trying to modify the board?
ZYG: I’m just trying to solder that small. Usually I solder bigger things but it has the soldering pads to attach components to it. The last project I’m working on is my MakerSpace project, which is the prosthetic hand controlled by muscle signals.
MS KINCAID: Can you tell us about that?
ZYG: Basically it works with 5 servos connected to string that attaches to each of the 3D printed fingers. When the servo turns one way, the finger closes, and when the servo turns the other way, the finger opens. I control it using muscle signals with a control board connected to a microcontroller like an Arduino. The part connected to the muscle uses EMG [electromyography] to measure difference in electricity between different points on the arm. It uses this EMG to figure out if the person is trying to flex or relax. This works because muscles use actin and myosin fibers, triggered by electrical impulses and powered by ATP.
MS KINCAID: What is your goal?
ZYG: I want to make a very cheap prosthetic hand where you can move each finger independent of each other. Right now your options are: a cheap one that closes all fingers at a time, which is bad for writing or holding circular objects, or an independent-digit expensive hand for around $10,000. Mine would be $150-200 but with independent digits. I would want to program patterns into it for set hand positions because it’s hard to program in each muscle.
MS KINCAID: If this is meant for someone without those muscles? Where would the signals come from?
ZYG: Right now, I control it via my forearm. This is designed for somebody who has no wrist, but still retains most of the forearm, so you can still use the muscles of the forearm. Closing and opening the hand uses muscles in the forearm, not the hand or wrist. Just using the forearm is a bit harder, but you can learn to do it. Studies have shown that with training, you can learn to use your brain to control a whole prosthetic arm.
MS KINCAID: That is cool! Would the stickers with wire be attached to your temples, then?
ZYG: You wouldn’t use the stickers, you would use the headset that goes over your head and measures alpha brain waves. You can’t really control an arm with that outside of the lab because you would have to get something implanted in your brain to control the arm, and you can’t do that outside of the laboratory.
MS KINCAID: So I guess that’s where we are today, and we’ll keep moving forward with the technology. Thanks Zyg, I feel like I learned a lot today!
ZYG: Thanks, you too! Bye!
As Mr. Bradfield, Zyg’s MakerSpace teacher commented, “It was inspiring to see Zyg applying the design and engineering principles he learned in class to a real-world problem.” It is inspiring to see our students take what they learn and help make the world a little bit better!

Statement from Jaden Penhaskashi:
As the new Science Academy President, many students reasonably expect a lot from me, due to the high bar our previous President, Lorelei Santa Maria, set. Although I would like to make many improvements to our already wonderful school, as the saying goes, “If it ain’t broke, don’t fix it!” My first order of business will be to continue all the amazing events put into place by our previous ASB, with some additions made in order to increase both school spirit and student involvement.
I will also prioritize finding a way to get more student feedback and increase the communication between ASB members and the general student body. Last year, there was an active tutoring program where older students helped many students who needed academic support. This year, however, that program has begun to slowly fade due to conflicting schedules of high school students. I plan on working with the school administration towards a solution. Finally, as a Science Academy high schooler, I know that many people in 9th and 10th grade feel that the school is treating both high school and middle school students as being the same. I would like to discuss with the ASB different ways to give high schoolers more privileges than they have at the moment.
I look forward to working with both ASB members and my fellow students towards improving our school, one step at a time! If you currently have any concerns or ideas on how to improve our school, please email me at firstname.lastname@example.org. I would love to hear your feedback!
Last Thursday, our campus was overrun with angels, devils, aliens, pirates, dinosaurs, cheerleaders, witches, and goblins!
Hope everyone had a frighteningly good time! The winners of our Costume Contest will be featured in the Yearbook – be sure to order yours soon. Thank you for everyone who participated!

In the North Hollywood community near the school, there are many fun places to explore, like the North Hollywood Park. The address of the North Hollywood Park and Recreation Center is 11430 Chandler Boulevard, North Hollywood, CA 91601, which is 1.8 miles from the Science Academy. There are many features in this park that makes it a fun place to visit with your family and friends.
One of the features in the North Hollywood Recreation Center is it has an outdoor fitness section. This area has equipment pieces for push-ups and sit-ups, as well as bikes, ellipticals, twisters, etc. Because of all the equipment they have, you have a lower chance of getting bored. In addition, there is a large track where you can jog and run.
This park is usually not crowded, so you can have plenty of open room to play or exercise. You also can have picnics there and enjoy the sounds of the birds chirping, while eating a sandwich. Right next to the picnic area, you can see dogs roaming around. That’s because right next to it, there’s a dog park. This park has improved a lot since the past. There are also many areas to play soccer and many other sports that involve running, with lots of trees that provide shade even when it’s hot outside.
There is also a library next to the North Hollywood Recreation Center called the North Hollywood Amelia Earhart Regional Library. The address of this library is 5211 Tujunga Ave, North Hollywood, CA 91601. It is a one-story red brick building. Its sloped roof is made up of red tiles and 2 chimneys on the end. The roof is supported by a row of concrete columns and capitals leaning on a concrete wall. When you enter, there is a small lobby with decorative iron gates with Mexican-styled windows framed with antique green glass. In addition, they even have a fireplace.
The history of this library dates back to the early 1900s when books were borrowed and returned in a corner of the Lankershim post office. When the city’s name “Lankershim” changed to “North Hollywood” in 1927, the name of this Lankershim Branch changed into Sidney Lanier Branch. In 1956, architect John Landon renovated it, so that it almost tripled the library’s size. The branch changed its name to the North Hollywood Amelia M. Earhart Regional Branch in 1980. Amelia Mary Earhart was an American aviation pioneer and author, the first female aviator to fly solo across the Atlantic Ocean. Even though she lived in Los Angeles less than 2 years before her death, this park honors her with her own statue and the library’s name. The statue is in front of the North Hollywood Amelia Earhart Regional Library, and down the street from another Earhart memorial at Valhalla Cemetery. The statue’s base is circled by 10 propellers halfway into the ground to honor her plane ́s actual resting place in the West Pacific.
The North Hollywood Amelia Earhart Regional Branch Library was designated an historic monument by Los Angeles in 1986. This historic building closed for repairs after the 1994 Northridge earthquake, and the library temporarily moved to MCA/Universal. The renovated building re-opened on April 17th, 1995. Within several years, because of the growth of the population in the area, the library had become crowded again. Architects and engineers expanded and restored the building, expanding the library facility to 15,150 square feet.
In conclusion, this park is very unique and interesting and has a great impact on the community of North Hollywood. Perhaps you can visit sometime after school or with your family and friends on the weekend.
This is a picture of the North Hollywood Recreation Center Building. It hosts the indoor basketball court, where people can play basketball in or join the Basketball Clinic (Youth)/League (5 – 15).Read More

As incoming 6th graders, we interviewed ten eighth-graders and Ms. Welch for their advice to the new sixth graders in the Science Academy because they have already been through the process of succeeding in the Science Academy.
- Do not procrastinate or panic about school work, even when we are under extreme pressure to finish with an upcoming deadline.
- When you are doing essays, you should try to calm yourself and think clearly before you start writing. You should not have your mind cluttered with extraneous thoughts.
- We should always try to get extra credit whenever it is available. This will give you extra points to get rid of a bad grade and stay at an A. Then we can still get an A, even if we miss a few problems.
- We should follow directions very precisely, participate constantly in class/ask any questions you have, and by doing this, you can understand tough concepts. They also said that we should make sure to keep our textbooks in good condition and to not lose them since we have to return them at the end of the year and they’re expensive!
- Another bit of good advice we received is that we should always get your homework done because it’s easier to keep up than it is to catch up. Participate in class, pay attention, ask questions if you don’t understand, and always write your assignments in your agenda so that you do not forget any.
- We also asked Mrs. Welch for her advice. She said that everyone should regularly check Schoology and that their parents also should. She also said to take advantage of Social Communication to do homework, collaborate, and get help on assignments. During this time you can get lots of homework done, giving you more free time at home. She also said to ask teachers for clarification whenever we do not understand something and to take advantage of lunchtime tutoring in different teacher’s classrooms and from other students in the Science Academy. The last piece of advice she gave us is to always be expanding our circle of friends.
- Take good, clear notes, use our agenda to its fullest, and to not talk to your friends during class or you will miss the information being taught and get bad grades on tests.
- One student advised us to not worry too much about the high expectations and warnings issued by Mr. Lauchu and Ms. Huff, that they really want what’s best for us and they can be understanding if things don’t go the way they should.
- Sixth grade is not very hard if you are a good student. They also said that we should do the outlines yourself so we actually learn the material and figure out what the primary aspects of a subject are.
- We should try to make a lot of friends and not be too hard on yourself if you get a bad grade on a test.
If you follow this advice, you’ll be a long way towards having a successful first year at the Science Academy STEM Magnet!
