Human Circuit VWR Essentials

Get Hands-On (Literally) with Conductivity •    Durable materials for years of use. •    An excellent fit for student-generated questions and experimental design.   Interactive energy tubes are ideal for teaching students about open and closed circuits, conductors versus insulators, and light and sound waves. When you hold both ends of the energy tube, your body becomes the conducting material. The gap between the two metal electrodes on the tube is bridged and your body creates a closed circuit. The result is that the energy tube produces sound and red, green, and blue LED lights flash. Engage the entire class using the students as “wires”: while holding hands in a circle, apply known insulators/conductors and unknowns to the circuit. Elevate this lesson by incorporating the included simple circuits kit and testing student-generated circuit diagrams. This kit includes enough materials to engage EVERYONE in the classroom- just hold hands. Ordering Information: Kit includes two energy tubes, the simple circuits kit, and teacher’s guide. NGSS STANDARDS 4-PS3 Energy 4-PS3-2. Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.   5-PS1 Matter and Its Interactions 5-PS1-3. Make observations and measurements to identify materials based on their properties. MS-PS2 Motion and Stability: Forces and Interactions MS-PS2-3. Ask questions about data to determine the factors that affect the strength of electric and magnetic forces.
