Cell Diffusion Exploration

Posted November 19, 2017

On Friday in Science Lab, the 7th grade explored the concept of how cells maintain homeostasis by allowing materials in and out of the cell through the process of diffusion. In this lab the students used a suspension of cornstarch and water to represent a cell, plastic wrap to represent the cell membrane, and various concentrations of iodine solutions to represent the raw materials a cell needs to perform life processes. The variables tested were the various concentrations of the iodine and various temperatures of the cornstarch suspensions. The students hypothesized about how these variable would affect the rate of diffusion into or out of their cells.

Saving Turkeys a Week Before Thanksgiving!

Posted November 14, 2017

SLS Middle School students used logic, communication and collaboration to solve a series of challenging digital puzzles and successfully completed a Breakout challenge. St. Louis School is introducing the BreakoutEDU platform to help improve our student’s critical, observational, non-linear and problem-solving skills. The Thanksgiving-themed lesson challenged students to unlock a series of puzzles and ultimately free a virtual turkey. To learn more about the educational benefits of BreakoutEDU visit:

Twenty One Elephants

Posted October 7, 2017

Our students in Mrs. Birman’s third grade class had a blast today when presented with a cross-curricular STEM/reading project. They read a story called “Twenty One Elephants” as a part of a unit on bridges that they are working on in Reading. The story is about Barnum's circus elephants, and how the circus had the elephants cross the Brooklyn Bridge in 1884 to prove that the bridge was safe. Students were tasked with designing a bridge using classroom materials such as cups, popsicle sticks, straws, clay, rubber bands, etc. The design had to be able to hold twenty one "elephants," which they modeled with math counting cubes. The students worked together in teams and all made a successful bridge that could withstand the weight of the cubes. They did an amazing job! #STEMatSLS#3rdgraderocks

Cyber STEM Fun!

Posted October 5, 2017

Today we kicked off the fall Cyber STEM session today with a collaborative balloon tower challenge where teams of students from a variety of grades worked together to create the tallest free-standing balloon structure in a limited amount of time. It was an opportunity for Cyber STEM students to meet each other, use their communication skills to plan a tower design and execute their plan. The sound of popping balloons was an added bonus!

We concluded the afternoon with an introduction to the Python programming language, beginning with the Python’s turtle drawing feature to create shapes of different colors. #STEMatSLS

“On your mark, get set, flow!”

Posted October 3, 2017

Our First LEGO League (FLL) coaches kicked off the 2017 season by attending the annual Maryland FLL Kick Off at UMBC this past Saturday. We are particularly proud of Coach Anne Reed, who was invited to lead a session and share her knowledge and expertise with other coaches.


SLS is sponsoring three teams this year and we look forward to seeing their work in the area of hydrodynamics, this year’s current challenge. “What might become possible when we understand what happens to our water?”

The Early Bird Gets the STEM

Posted September 10, 2017

Three St. Louis teachers, Ms. Frederick, Mrs. Riggin and Mrs. Whiteford, woke up before the crack of dawn to attend a day of STEM professional development at the United States Naval Academy. The theme for the day was Engineering Design and it included lessons on hydraulics, electrical circuits and fundamental mechanical machines. The program culminated with an engineering challenge to design and build a missile replacement mechanism for the NAVY. To learn more about the USNA STEM program visit:

Aquaman's Sidekick

Posted April 8, 2017

If Aquaman is looking for a mechanical sidekick, the St. Louis AquaKnights have the answer! Our underwater engineers have designed a clever remotely operated vehicle (ROV) and will represent St. Louis School at the MATE  (Marine Advanced Technology Education) competition at Villanova University next Saturday, April 15th. A huge Thank You to our superhero coaches Mr. Kerechanin, Mrs. Fatula and Mrs. Ghatti for giving this opportunity to our students. We are proud of the AquaKnights and wish them the best next weekend.
