Camp Cedar Hill Waltham, MA (map)

STEM Fest is GSEMA’s premier STEM event of the year, and is open to ALL Girl Scout levels with activities and experiments created and designated specifically for different ages. 

It’s a STEM takeover at camp! Explore fun hands-on science, technology, engineering, and math challenges throughout Camp Cedar Hill. Local partners will be stationed all throughout the camp property so you can use your map to choose your own adventure and decide what areas and topics to explore. Meet and chat with STEM professionals while digging deeper into topics you love or discovering new ones that you may not have previously known about!

Join Us for Our STEM Fest Keynote Address! 

Girl Scout Daisies, Brownies, Juniors, Cadettes, Seniors, and Ambassadors are invited to this year’s STEM Fest keynote speaker event!  This year, the keynote will be structured as an informal “fireside chat” in the Council Bowl at 11 AM. Please keep in mind that while all are welcome to attend, it is recommended most for Girl Scout Juniors, Cadettes, Seniors, and Ambassadors. 

Meet our Keynote Speaker!

Women designer and architect speaker

Laura is a designer and architect with eight years of experience. Her works spans building types, project scales, and geographic settings in the Boston area. Originally from Cincinnati, her favorite hometown building is Music Hall, noted for its Victorian-Gothic style and magical performances. Laura received her Master of Architecture and B.S. Architecture from the University of Cincinnati.

Outside of architecture, Laura enjoys artistic pursuits like photography and videography, in addition to video and board games. She enjoys questioning the spaces and constructs around her, and often finds herself thinking about how and why things work (or don't).


Plan Your STEM Adventure

Daisy Activities (grades K-1)

Coding for Video Games and Fun with Robots

Minecraft is a game with tons of possibilities, but have you ever wanted to create your own piece in the game? Join us and learn to code your own block, design, or other tool and import your creation into the game. Then, continue to test your coding skills by trying to successfully get a robot to go through an obstacle course.

Big Whale, Tiny Plankton

Whales are some of the biggest and most powerful sea creatures known to man, but they love snacking on some of the sea's tiniest delicacies! Examine the difference between these two creatures by studying whale bones, and teeth, and then use a microscope to look at and identify plankton. 

The World's Coldest Ice Cream

Liquid nitrogen isn't just for cool science experiments! You can use it to make delicious desserts in a way you would have never thought possible. Join us in this exciting session for a tasty treat with a twist. 

DIY Bandages

Bandages are something we are all familiar with, but have you ever thought about what goes into making them so effective? Try to make your own brand-new bandage design and put it to test it in an exciting obstacle course!

Smokin' Bubbles

What happens when you combine dry ice and soap? Smokin' bubbles, that's what! Come learn about what makes these types of bubbles so unique, and get creative by adding a touch of color and making them "pop" even more!

3D Printing in Action

You may have heard of 3D printing, but what can you do with it and how do 3D printers work? Come learn how you can make almost anything with a 3D printer, and then get your own 3D-printed object!

Taller and Stronger: Building Structures

Design and build a structure using everyday materials, your creativity, and your existing STEM skills. Push yourself to the limit by making the tallest and strongest structure that you can make before putting it to the ultimate test.

Ultimate Lego Construction Challenge

Are you ready for a challenge? Create a structure in ten minutes using Legos, a rock, and aluminum foil. Present your structure in front of construction professionals and see how your design compares with their real-life projects.

Robotic inventions can solve decades-old problems, but they can also be a ton of fun. Join us for this exciting robot-building session, solar-powered bug, and watch it dance in the sunlight!

Morse Code Bracelets

Trade secret messages with Morse code bracelets! Code and decode silly-phrases with your friends. and where them on your wrist for all to see (though few will be able to understand).

Popsicle Stick Explosion

Learn about the importance of a truss and its real-world applications by creating a chain of popsicle sticks. Remove one piece and watch as the structure falls apart, teaching each participant the true meaning of a "chain-reaction".

Candy or Medicine?

Calling all future pharmacists! Explore a potential career path, learn to use a pharmaceutical tray, and practice reading medication labels. Finally, use your newfound knowledge to compete in a game where you will differentiate between medication and candy!
