Caution – High Voltage Circuit

LET’S GO hosted its Third Annual Spring Pop-Up Event in collaboration with Northrop Grumman Undersea Systems, Maker-Kidz, and Annapolis Maritime Museum in May and it was a huge success! Overall, this was LET’S GO’s fourth STEM event.

Attendees created musical pencils using electrical circuits called Drawdios. Students learned; the difference between open and closed circuits, what resistors do, and the components of a breadboard all while building their own Drawdio.

Ohm’s law was explored. It states that the current through a conductor between two points is directly proportional to the voltage across the two points. Introducing terminology allows students to construct explanations based on their observations. As a part of the Engineering Design Process which is iterative or applied repeatedly, students learned to go with the flow and persist as they troubleshoot their circuit designs.

But the fun didn’t stop there…

Students also splashed into environmental science, getting their hands wet, as they tested the water quality for a tributary of the Chesapeake Bay. The water chemistry experiment helps students understand how scientists determine quality levels will impact the inhabitants of this Annapolis ecosystem. The Maryland Blue Crab made a guest appearance.

Students also had the opportunity to engage with professional scientists and engineers in an informal and casual way leading to great conversations about how to succeed in a STEM profession. We look forward to offering this event again in 2020!
