3rd Grade Lights LEDs!


This week, third graders began a study of circuits and electricity. During the first part of class, students had to figure out how to light up an LED using a coin cell battery and two alligator wires. It was very exciting when the bulbs turned on when our circuits were properly completed!

In the second part of our exploration, students used their alligator wires to test various materials to determine whether they conducted electricity. We found that craft sticks, magnets, string, and rubber bands did not allow electricity to flow through, but pipe cleaners did complete the circuit. Finally, students roamed the STEM lab looking for more materials that would complete the circuit when they were incorporated into it.

In future explorations, we'll be working on creating circuit sculptures using conductive dough.

Technology Club: Scratch

For the past two months, second and third grade students participating in our after school Technology Club have been using the block-based coding tools in Scratch to create animations. In the club, students tinkered with graphic design, sound, and coding to bring their ideas to life. Check out some photos of their designs!

5th & 6th Graders Invent Baby Products!

 During their fall STEM classes, 5th and 6th graders acted as inventors and entrepreneurs as they devised and created prototypes of innovative baby and toddler products. Students began their work by developing a list of potential challenges or problems facing babies and new parents and then selected a problem to try to remedy with a new invention. After developing their concept and thinking about the features of their products, students then built prototypes and created advertisements for their inventions. Finally, students presented their work to their classmates and tried to convince Ms. Hewes that their items would help make her life as a new parent easier.  With thoughtful and creative ideas ranging from RFID-enabled baby gates, diaper-changing robots, self-walking strollers, and a wide variety of educational games and toys, it wouldn't be surprising to see some of these products on store shelves someday!
