Welcome to Arroyo Seco . . .

Arroyo Seco Museum Magnet School is a beacon for educational innovation and academic excellence.  From our unique magnet focus to the unequaled museum experiences it provides, we are committed to providing our students with a brand of elite academic preparation.  The hallmark of our success is not only limited to the intelligent, capable students we produce but it is also found in our remarkable corps of highly qualified, dedicated and caring faculty and staff.

As our reputation for academic excellence has grown, so has the prospective interest.  We recognize the special gifts and talents of every one of our students and work diligently to help them realize their potential as future leaders and innovators of the world.  Our students will go on to enjoy the privileges earned by their individual achievements but will do so with a motivation greater than material reward.  Arroyo Seco Museum Science Magnet strives to produce talented, thoughtful leaders capable of entering the world on their own terms and leaving it better for us all.

"I believe profoundly in the importance of museums; I would go

as far as to say that you can judge a society by the quality of its museums.–R. Fortey


In Museum Science Studies courses students will learn the roles that museums play in our society. They will learn about specific museums.  They will learn why they were created and how they are funded, managed, and organized.  Students will visit and evaluate museums in Los Angeles, including virtual exhibits.  They will develop analytical and critical skills by reading, discussing and debating different museum exhibit collections.  Student will have the opportunity to work directly with staff from the Autry National Center to learn the seven key roles that museums must fulfill in society and the types of jobs that can be found in museums.  Once students have a strong foundation in California history, they will begin working to develop a field trip program for fourth grader students in Los Angeles area schools.  They will provide history tours of the Casa de Adobe, a replica of a traditional California rancho home.

Ready, Set, Gold!

Ready, Set, Gold! is working to eliminate childhood obesity — one push-up at a time!

Obesity is one of the greatest health challenges facing our country, and related problems such as diabetes are on the rise as well.  Experts agree that increased exercise is key to fighting obesity and that it’s important to start healthy habits early.

As the first and only program of its kind in the country, Ready, Set, Gold! tackles this epidemic problem by pairing Olympic and Paralympic star athletes with Los Angeles area public schools to promote student fitness and inspire a future generation of college and Olympic athletes.  Each athlete meets with their school’s physical education classes six times during the academic year to educate and motivate the students, and by extension their family members, toward a long and healthy drug-free life through fun physical activity and proper diet.  During the structured school visits, the Olympians and Paralympians exercise with the students and share stories of how they became world-class athletes and the importance fitness and nutrition played in their success.


Mr. Plascencia's Block 4 7th grade PE class has had the opportunity to work with Candace Cable, Paralympian this school year.  Disaster invaded Candace Cable’s life in 1975 when she suffered a spinal cord injury in an automobile accident. At the age of 21, she would never walk again. However, out of this tragic circumstance emerged a woman with the character and will to become one of today’s most successful world athletes.
Candace Cable has been ranked number one nationally in wheelchair racing competition from 1984 to 1990. Furthermore, internationally, she has won 75 marathons, including six Boston Marathons (1981, ’82, ’85, ’86, ’87, & ’88) and has set world records in every distance throughout her 21-year career. Winning two Olympic medals in three Summer Olympic Games, Candace participated in the only exhibition event for the disabled. Additionally, she has won nine Gold medals in five Summer Paralympic Games. Since 1990, Candace has been competing on the United States Disabled Ski Team, winning three Paralympic medals on the Alpine team. In 1994, she switched to the Cross Country Team, and is currently on the “A” team.  Showing “limitation” as a state of mind, Candace has spoken all over the country about the celebration human spirit strength. Using examples from her own life, she demonstrates how both able-bodied and disabled individuals face similar struggles to realize their fullest potential. She focuses on: re-evaluating our lives constantly, not setting limits on ourselves, keeping a sense of humor, staying physically fit to be mentally fit, and taking complete responsibility for our lives. From dispelling the myth that if you have a physical disability you cannot be a whole person, to finding solutions to life’s problems through creativity and imagination, Candace can help you see “disability” is only a word.

And now a word from one of our students:


Hello Ready Set Gold,

My name is Emily Hernandez and I am very proud to be the winner of the Fitness Gram competition for my class.  I expected to get a high score because I was practicing very hard at improving my scores in the PACER, curl-ups, and push-ups.  I was surprised because I did not think I would win the watch.  I am so appreciative for Ms. Cable coming out to our school to share her stories and give us information on the Paralympics.  I really enjoyed the videos she shared because they showed me that even if you have a disability you can still enjoy playing sports and being a part of a team.

Arroyo Seco at Vex Robotics- MS and HS Division

Over the weekend, our M.S. robotics team led by Mrs. Griffith successfully competed in the middle/high school VEX Robotics Competition at John Glenn H.S. in Norwalk. We were the only LAUSD middle school 

competing against 29 other middle and high schools throughout Southern California. 

Despite some early programming difficulties, Team Arroyo persevered and eventually placed 17th of 30th in overall team ranking. 

As newcomers to robotics, both our E.S. and M.S. teams exceeded expectations and performed exceptionally well at the VEX events. Our novice group of aspiring engineers, programmers, and designers 
showed great poise and  pride in representing our school and district at competition this year. With this great learning experience under our belt, we're determined to do better next year!
Kudos to Mr. Koneazny and Mrs. Griffith for providing our students STEM leadership and opportunity to engage in robotics at Arroyo Seco!


Arroyo Seco at VEX IQ Robotics

Our elementary robotics team led by Mr. Koneazny successfully competed in the VEX IQ Robotics Challenge on Saturday, Feb. 4, at El Camino College in Torrance. Being a rookie team, our Cougars robotics team outcompeted many teams from other districts, some with more experience and resources, and did an outstanding job placing 15th of 34 in Skills and 19th in Teamwork rankings.  We're very proud of you for representing Arroyo Seco of Highland Park and LAUSD at our first ever VEX Robotics Competition. Your perseverance, teamwork, problem-solving, and passion for robotics were on full display throughout the event. Great effort, Cougars!




Today: 7/28/17


Dear Parents:


I welcome you and your students to the 2016-2017 school year.  It is a pleasure and an honor to have been chosen as the principal here at Arroyo Seco Museum Science Magnet.  I am very excited about getting to know each and every one of you and working together as a team to ensure the safety and academic success of our students.  There is an African proverb that states: It takes a village to raise a child.  I am proud to now be a part of the Arroyo Seco village.   


This is my thirteenth year as a principal.  I come to you with a variety of experiences.  I have had the opportunity to hone my organizational skills in large, year round schools in South Los Angeles.  I am bilingual in Spanish.  I have worked tirelessly on social emotional learning and anti-bullying.  I have ensured that all students have access to the full curriculum, including the arts.  And I am a proponent of developing the leader in each and every student. 


This year, we will focus on safety.  I have already met with district personnel regarding the access to the school through the parking lot, the need for a security gate, the need for a window in the main office and the need for a restroom on the upper campus for Middle School use.  I was informed that we are a candidate for the Light up your Library program, which is a refurbishment of the library.  I am working with a printer to get banners that explain the difference between rudeness, meanness and bullying, which is such an important concept for our students to learn. 


Our academic focus this year will be on the Next Generation Science Standards and how they relate to Museum Science and, of course, literacy and numeracy.  I am excited that all students, grades K-8, will have the opportunity to visit the Huntington Library this year.  Additionally, we will have a Visual Arts teacher here one day a week for the entire year, and a music teacher here two days a week for the entire year.  The opportunities for connections and learning and growing our knowledge of Museum Science are endless.  


I look forward to meeting you in person.  We will be establishing our Local School Leadership Council, ELAC and SSC, as well as holding our Open House as soon as possible, so please stay tuned.  Please feel free to contact me at 323-245-5141 or via email at robin.polito-shuffer@lausd.net.
