STEM Programs


As part of the science program at Dexter Southfield, each student is able to experience firsthand the process of conducting scientific observations during class visits to the observatory. Students are able to view the Sun, Moon, planets and the stars through the telescopes in broad daylight.
The telescopes are also available for night-time viewing by students and their families.
After School Science Clubs for Classes 3, 4, 5, 6, 7, 8+ 

The School is pleased to offer a variety of after school science programs. These are extracurricular, hands-on, enrichment clubs designed to encourage inquiry and learning in a fun, positive, educational environment. Clubs meet in the Clay Center and the Mouse House, from 3:30-5:30 p.m. or 6:00-8:00 p.m. on specific weekdays. Snack or dinner will be provided. Please note: There will be no bus transportation for after school attendees. Please click here to fill out the form to sign up. A lab fee for each enrolled club will be charged to help offset the cost of these extracurricular programs.


Spring Term 2018 Offered Programs 

Electronics Gadgets  (Class 3 and Classes 4–8)  

PURPOSE: Students explore how electricity works, create things that light up and make noise, and learn how to solder gadgets to take home and play with. Visit the website to learn more about this activity. For those who have not taken this activity before: 

CLASS 3 MEETINGS: Three Wednesdays, 3:30-5:30 p.m., April 25; May 2, 9. Lab fee is $90.

Making Things Club  (Class 3 & Classes 4–8)

PURPOSE: Use professional tools and software to design and make things, big and small. We generally work with things you can hold in your hand: anything serious or silly is a candidate for being made in this club, which is an introduction to 3D design and engineering. It helps to prepare students for the middle and upper school clubs. During the club, students will design and make objects they can keep. The club meets in the Clay Center Engineering Lab.

CLASS 3 MEETINGS: Three Wednesdays, 3:30-5:30 p.m., April 4, 11, 18. Lab fee is $90.

CLASS 4-8 MEETINGS: Three Wednesdays, 3:30-5:30 p.m., April 25; May 2, 9. Lab fee is $90.

CubeSAT Project with MIT Media Lab (Classes 6–10)

PURPOSE: This is a one-year academic and hands-on spacecraft-building program during which you will learn about rockets, space science, and climate research, then design and build a spacecraft that will launch into space in 2019. No previous experience is required. Scientists at the MIT Media Lab will co-teach with Mr. Dantowitz to help you learn everything needed to accomplish this project. Meetings involve regular field trips to MIT and Boston locations, so the meeting blocks are necessarily longer. This is a full-year project, so a commitment will require re-joining Tuesday meetings next fall and winter. You will have a unique and amazing experience to write about on your college applications.

MEETINGS: 11 Tuesdays, 3:30-6:30, March 6, (optional 13, 20), 27; April 3, 10, 24; May 1, 8, 15, 22. Lab fee is $280 per term.


2D LASER Cutter Design (Classes 4–8)

PURPOSE: Learn how to design and LASER-cut a wooden box for keepsakes. After designing your box and planning cuts and etchings, we will take a field trip to a maker lab to cut your box with an industrial LASER. Parents are invited to join us at the maker lab and watch how this is done. This is a beginner level class.

MEETINGS: Three Tuesdays, 3:30-5:30, March 27; April 3, 10. A field trip will be on Tuesday, April 3, during regular lab time. Lab fee $120.


Circuits Maximus (Classes 4–8)

PURPOSE: This activity is about designing and building electrical circuits. Students will use computers and chemicals to design and create electronic toys or wearable objects. Students must look cool wearing aprons, rubber gloves, and safety glasses. Note: You must have basic electronics and soldering experience to take this class.

MEETINGS: Four Tuesdays, 3:30-5:30, April 24; May 1, 8, 15. Lab fee $120. 


Ham Radio License Course (Classes 4–12)

PURPOSE: First-time radio students will build a working FM radio while learning about basic radio, earth science, space science, and electronics concepts. At the end of the course, students will take the Technician level radio license test and become FCC-licensed amateur radio operators. All ages are welcome. This is a beginner level course. Previously licensed students may take the next level and go for their General License. Both courses meet on the same dates.

MEETINGS: 10 Thursdays, 3:30-5:30, March 29; April 5, 12, 19, 26; May 3, 10, 17, 24, 31, in the Clay Center 5th floor. The radio license test is May 24 or 31, 6:30-7:30, with dinner provided. Lab fee $180.


STEM Club - Evening Program  (Classes 5–12)

PURPOSE: The STEM Club is designed to spark interest in science and train students to operate the huge Clay Center telescope! STEM topics and activities include optics, astrophotography, electronics, 3D design, Arduino programming, amateur radio, telescope instrumentation, drones, rocketry, and more.

MEETINGS: Most Wednesdays and Thursdays, 6:00-8:00, with an option to stay until 9:00 p.m. on clear nights for astrophotography. Some students stay for Homework Club first, then join this group for dinner at 5:30. Regular attendance is not required. March 28, 29; April 4, 5, 11, 12, 19, 25, 26; May 2, 3, 10, 16, 17, 23, 24.

Radio Club Meetings - Evening Program  (Classes 4–12)

PURPOSE: The Clay Center Amateur Radio Club (CC-ARC) meets regularly on Tuesday evenings. Meetings are open to all. Join us for educational talks or demonstrations, fox hunts (hidden transmitter hunts), making radio contacts around the world, radio contesting, building radio electronics projects, and more. Club members also build projects to fly on NASA rockets or high-alt balloons.

MEETINGS: Most Tuesdays 6:00-8:00, with an option to stay until 9:00 p.m. on clear nights for the telescopes. Some students stay for Homework Club first, then join this group for dinner at 5:30.
