Earlier this week, employees from Micron Technology visited our Grade 3 classrooms to teach students about magnetism and electricity in relation to their current Unit of Inquiry, “How the World Works.”
Using hands-on activities, our third graders explored how people use investigations, tools, evidence, and knowledge to learn and explain how magnetism and electricity work. Students rotated through four stations: 1) Static Electricity, 2) Magnets, 3) Circuits, and 4) Lemon Batteries. The class was able to experiment with materials such as volt meters, D-cells, bulbs, motors, magnets, lemons, balloons, pie plates and even a Barbie doll in order to explore the properties of magnetic materials and how various components interact to create electricity.
Following the visit from Micron, students drew electric circuits and discussed the challenges of manufacturing an invention using these drawings. This led everyone to learn more about schematic drawings. Using the first draft of their electric circuits, they edited their drawings into more professional ones and found it easier to share their creations with one another.
Both third grade teachers, Mrs. Wallace and Ms. Stewart, were thrilled to use the topic of electricity to develop critical thinking skills and warned parents not to be surprised if their student asks for electric components or a Van De Graaff generator to play with at home! The classrooms will be moving forward to focus on experimenting with insulators, conductors, and reading a bit about Michael Faraday, whose discoveries in the 1700s helped pave the way for the invention of the electric motor.
Thank you to the Micron volunteers for sharing their love of science with our students!
