The Miracle of Life
Posted June 15, 2022
The miracle of life extends to the world of plants. Ms. Rossi’s Fifth Grade Science class began a plant growth project in April by placing parts of a plant in water to encourage root growth. This week, with the plants ready for potting, they used STEM skills to build self-watering pots from recycled materials.
Students cut empty water bottles in half and used the top half turned upside down to hold soil for the plant. The bottom half holds water. In the mouth of the bottle is a paper towel wrapped in a coffee filter that pulls the water up to the soil.
Mrs. Riggin joined in and helped our students complete the project! #STEMatSLS #RiseAbove #AOBCatholicSchools

Planning for the Future
Posted June 15, 2022

In Math class, Fourth graders had a chance to take the roles of urban and city planner engineers to plan their very own city. They used the geometry concepts learned through the year and applied their knowledge by developing their own city map with geometric requirements.

Back on the Road!
Posted June 15, 2022

A key component of learning is self-guided exploration and the Maryland Science Center provides a perfect environment for this to occur. SLS Sixth Grade students increased their STEM knowledge today while exploring interactive exhibits including creating a water vortex, experiencing the inside of a tornado, and laying on a bed of nails. It was a full day of intellectual adventure and fun! Thank you to Ms. Peterson and Mr. Deegan for planning this field trip experience and to the staff at the Maryland Science Center for their guidance and support.

Fishers of Men
Posted June 15, 2022
In the book of Matthew, we read that Jesus found Simon Peter and Andrew along the shore of the Sea of Galilee, working as fishermen and casting a net into the water. He called to them and promised to make them "fishers of men." In a like manner, we are called to be disciples as well.
As a reminder of this calling, Ms. Miller's Sixth Grade Religion class was challenged to use their STEM design and engineering skills to make a net out of paper capable of holding at least six golf balls. Students were grouped into teams and got to work forming and weaving strips of paper into a usable net. One team managed to build a net that held 45 balls! #STEMatSLS #AOBCatholicSchools #riseabove

Thermodynamic Gas Law!
Posted June 15, 2022
Experimentation is a critical part of Science - and can be a lot of fun!
Mr. Hurst’s Seventh Grade Science class had a number of special guest mentors in the lab this morning when they hosted Mount Saint Joseph High School AP Chemistry students and their Chemistry teacher, Mr.Jason Ader.
Today's experimentation focused on the principles of the Thermodynamic Gas Law. Students used Alka Seltzer tablets as a gas generator to propel small canisters, observing how temperature affects pressure over time. For an hour or so there were little rockets flying all over the St. Louis Science Lab!
We would like to thank Mount Saint Joseph High School for providing a wonderful educational and a memorable experience for our students. A special thank you to our SLS alums, Nick and Drew for coming back and serving as outstanding role models. #stematsls Archdiocese of Baltimore Catholic Schools

How Many Puzzles Can You Solve?
Posted May 24, 2022

Pentominoes are two-dimensional shapes made from five square blocks that are joined edge-to-edge to form various designs. There are twelve possible shapes in a set of unique pentominoes. Fourth Grade students in Mrs. Ellerbrock’s Library class use pentominoes to solve STEM Math puzzles and to develop their critical thinking skills during small group work. How many puzzles can you solve? #stematsls



Codes and secret writing
Posted May 18, 2022
Codes and secret writing date back thousands of years. People have always tried to hide their messages from prying eyes. What makes a good code? How would you use one? How have they been used in the past?
St. Louis School is fortunate to have Mr. Mike Blasi, former SLS parent, STEM resource, and National Cryptologic Museum staff member as part of our continuing STEM Speaker Series. He spent the afternoon with the Class of 2022, explaining a variety of cryptographic methods and providing the students with challenges to solve. He spoke about Caesar and pigpen ciphers, frequency analysis, as well as the history of the Enigma machine and how it works. As an added bonus, the students had the opportunity to experience typing on an actual Enigma machine on loan from the National Cryptologic Museum. We want to thank Mr. Blasi and his daughter Laura, SLS alumn, for sharing their time and talent with our students. #STEMatSLS

Monopoly anyone?
Posted May 6, 2022

Over the course of a game of Monopoly, how likely is it that you would land on Boardwalk or Park Place? As part of our ongoing STEM Speaker Series today SLS Sixth Grade students had the opportunity to learn how to compute the answer to that and similar questions from Mr. Mike Blasi, former SLS parent, and STEM resource.  SLS students learned about real-world applications of probability and random processes. They learned how to form a hypothesis and test it using the scientific method. To make these concepts more relatable, Mr. Blasi discussed how dice and coin flips can affect outcomes in games like Monopoly, Risk, and Yahtzee. We want to thank Mr. Blasi for taking time out of his day and coming to SLS to provide a better understanding of probability, statistics and why they will almost assuredly not win the lottery.

AFCEA STEM Kickstarter Awards Banquet
Posted May 6, 2022
A portion of the St Louis School STEM budget comes from grants. We use these grants to purchase equipment and software that provides our students with hands-on learning opportunities.
Tonight we celebrated our third STEM Kickstarter grant award at the AFCEA Annual Awards Night held at the Turf Valley Resort. SLS Third Grade STEM Ambassadors demonstrated the capabilities of Wonder Workshop Dash robots we purchased with grant proceeds to a large and inquisitive audience during the first hour of the event. They explained the Blockly programming app and answered questions like: How do you make the robot spin in a circle? How many colors can you program the lights in? Can you make your robot turn in a certain direction 90 degrees?” Our Ambassadors did a remarkable job representing our school and we are very proud of them.
The evening included a delicious meal where the award recipients were recognized, followed by an engaging keynote address by Laura Nelson, the Chief Executive Officer of the National Cryptologic Museum Foundation.
St. Louis School would like to thank AFCEA Central Maryland (CMD) for their continued support of our teachers, students, and our STEM program.#STEMatSLS Archdiocese of Baltimore Catholic Schools

Dash Winter Olympics
Posted March 17, 2022
While the official 2022 Winter Olympics took place in Beijing, here at home our St. Louis School Third Graders held their own competitive sporting event. In a collaborative effort between Math, ELA, Library, and Computer class, the students learned about the Olympics and researched their assigned sport and country. Students were then split into groups and programmed Dash Wonder Workshop robots to perform the appropriate actions for each sport and then measured the resulting time and speed.
The purchase of these Dash robots was made possible by a grant from AFCEA Central Maryland (CMD). We are grateful for their continued support of our STEM program.
The St. Louis Olympics included an Opening Ceremony and the events were cheered on by spectators of all ages. Every team successfully completed their programming sports challenge and demonstrated terrific sportsmanship. Check out this video to learn more. #STEMatSLS #Archbaltschools
