Maryland STEM Festival Podcast

Take a few moments to listen to our STEM Coordinator, Mrs. Zulma Whiteford, as she talks about all things STEM-related at SLS and our participation in this years' Maryland STEM Festival! Thanks to Mrs. Whiteford for her passion and leadership and for engaging our students with creativity and collaboration! #STEMatSLS Archdiocese of Baltimore Catholic Schools

Narwhals at Catholic Robotics League Expo!

Summer is here and school is not in session, but we continue to highlight some of the great activities and accomplishments of our students during the past year.

Earlier in May, the Einstein Narwhals participated in the Catholic Robotics League (CRL) Expo at Baltimore Robotics Center in Timonium. The team shared their project, their experiences at the World Championship, ran their robot program as part of the competition and assisted with judging. A huge thank you to coach Anne Reed and team member Maggie Reed for offering their expertise with judging. It was an engaging and fun morning of competition with our fellow Archdiocesan teams. We look forward to many more!

Can You Break Out?

Ms. Frederick’s Fifth Graders have been studying the events leading up to the American Revolution. They learned that spies and secret messages were common place while colonists decided which side of the Atlantic their allegiance fell. They put their “spy” sense to work today figuring out clues and secret messages in prime resources from that time period. The students loved working as a team to find missing papers they needed to, “Breakout!”

Revealing Medical Mysteries

Did you know that optical fibers can be woven into bandages to help monitor wounds?

Seventh Grade students explored advancements in medicine during their trip to the National Museum of Health and Medicine in Silver Spring. The museum, established during the Civil War in 1862, is designed to inspire curiosity and promote the understanding of medicine - past, present and future - with a focus on the Armed Forces.

Students learned about the process of plastination to preserve organs, developed by Gunther von Hagens in 1977, innovations in surgical repair techniques like facial reconstructions and much more. They had an opportunity to explore the exhibits, complete an exploration guide, listen to presentations and ask questions. To learn more about the museum visit:

Students also enjoyed lunch at Brookside Gardens, where they were able to walk around the park and explore the beautiful grounds and gardens.


Cup Stacking Fun!

Learning can take place at any time and some of the best lessons come from hands-on activities. Sixth Grade students at St. Louis had the opportunity to engage in the 4 C's of STEM after finishing a final exam. The students used creativity, collaboration, communication and critical thinking to design and build free-standing towers using cups. Take a look at the fun-filled results!

Withstanding the Wolf!

Can you design and build a structure strong enough to protect the Three Little Pigs from the Big Bad Wolf? After reading the story, Mrs. Tyler’s PreK students were challenged to select materials, create a blueprint and build a structure to be put to the test. They used the STEM concept of iterative engineering to test their design, improve and correct any weaknesses and test again. The hair dryer huffed and puffed but the STEM-engineered houses did not fall down!

Save the Oceans!

What happens to all of the plastic that you throw away each day? Sadly, much of it ends up in our oceans. There are an estimated 5.25 trillion pieces of plastic debris in the ocean, and of that mass, 269,000 tons float on the surface, while some four billion plastic microfibers per square kilometer litter the deep sea. This trash is negatively affecting ocean life and ultimately reaches the human food chain.

Mrs. Yuska’s Seventh Grade Science class took up the challenge of looking for solutions to this pollution problem. The students worked in groups to research the answers to the following questions: What negative effect do humans have on the Earth's oceans? What impact does trash play on the ocean ecosystems? What responsibility do humans have with regards to trash and the Earth's oceans?

After understanding the problem, students were given guidelines on developing a device to remove this trash, including that it must not be harmful to marine life, must be scalable and sustainable.

Although the prototype devices were constructed from cardboard and were not actually deployed to the ocean, one of the fundamental purposes of STEM education is to teach the skills that are necessary for effective problem solving. We teach students how to think critically about a problem and how to work collaboratively to develop solutions.


Following in Roman Footsteps

What kind of architecture did the ancient Romans use?
How do we still rely on this architecture today?
What allows the Roman arch to hold so much more weight than other structures?

These are just a few of the questions that were answered during Ms. Miller’s Sixth Grade Ancient Roman Architecture cross-curricular lesson. The students were introduced to Roman architecture and were guided through a research process during Library/Media class. Upon completion of the research, the students designed on paper the arch model they thought would hold the most weight and followed up by building their design in clay. The groups then tested their design by placing books and other heavy classroom objects on top of the clay model. One of the arches even held Ms. Miller! Everyone was impressed by the successful designs of ancient Romans.


Breakout EDU

Our Breakout EDU boxes have arrived and teachers are excited to incorporate them into their classroom! Breakout EDU is an engaging learning games platform where teachers turn their classrooms into academically-focused puzzles and where students use critical thinking skills while collaborating with team members to solve the challenges and unlock the box. Breakout EDU games are available for all grade levels and subject areas. To learn more about Breakout EDU visit:

Whooo...was for dinner?

Mrs. Riggin’s Fifth Grade ecologists have been busy learning about ecosystems, food webs and food chains. This week in Science Lab they investigated what owls eat by dissecting owl pellets. They learned that owls swallow their prey whole, absorbing the nutrients but not the inedible components including bones, feathers, fur, etc. Owl stomachs produce these pellets of indigestible parts, which are then regurgitated. Students dissected the pellets and matched the bones to a chart of various small animal bones. Some students even found entire skulls in their pellets!

Aqua Knights Win!

The Results are In! The St. Louis School Aqua Knights won First Place for product presentation, Second Place for robot demonstration and Second Place overall. We would like to thank the coaches, Chuck Kerechanin and Angela Fatula, for their gift of time and talent to make this possible. We would also like to thank the Aqua Knights parents for their enthusiastic support of the team. The St. Louis community is proud of their hard work, dedication and ultimate success!

Aqua Knight Update!

The Saint Louis School AquaKnights have completed the morning competition and are awaiting final results. They had a very successful robot run in the water and marketing presentation.

The AquaKnights are in a select group of competitors, being one of just 35 teams and the only team from Maryland. Other teams hail from New Jersey, Pennsylvania, DC, Virginia, New York and Ontario, Canada.
