This classroom instrument consists of a transparent plastic iron powder box with a rectangular inner cavity containing an appropriate amount of iron powder, paired with a magnet. It is designed for use in middle school science experiments to demonstrate how magnetic forces influence ferromagnetic particles. Key benefits Clear visual demonstration: Transparent plastic box and loose iron powder allow students to observe particle movement and arrangement in real time. Simple, handson operation: Use the included magnet and change the tilt direction of the box to produce visible motion and patterns without complex setup. Designed for classroom use: The rectangular cavity and measured amount of powder provide repeatable behavior that supports lesson plans and group activities. Reusable learning tool: The components are ready for repeated demonstrations and student experiments. Primary attributes Function: Visualizes movement of iron powder under the influence of a magnet and under changes in box orientation. Compatibility: Intended for middle school science classes and laboratory sessions that cover basic magnetism and particle behavior. Material: Iron powder contained in a transparent plastic box; magnet supplied separately. Form factor: Box has a rectangular inner cavity sized to contain an appropriate amount of iron powder for clear observation. Performance: Iron powder shifts and reorients when the box is tilted or when the magnet is moved, enabling observation of magnetic effects and particle dynamics. Use scenarios Teacher demonstration: Place the magnet near the exterior of the plastic box and tilt the box to show how iron powder flows and aligns, illustrating magnetic influence and particle movement for the whole class. Student lab activity: Small groups test how changing the box tilt or magnet position affects the distribution and motion of the iron powder, then record observations and discuss underlying magnetic principles. Interactive science fair exhibit: Provide a handson station where visitors manipulate the magnet and observe the iron powder response to different tilt angles and magnet placements. This instrument offers a straightforward, observable way to support lessons on magnetism and particle behavior without additional accessories or complex preparation.
