As you know, convection plays a major role in Earth systems. Here is video that shows a colorful way for students to cause convection . . . and then watch as it happens. The video shows the second part of a two-part activity that helps students understand the role convection plays in causing wind. Both parts, as well as the student handout, are included in a kit available from WARD's. CLICK HERE to see the kit, which also includes an activity related to ocean currents. CLICK HERE to watch a video of that activity. The student handouts (one for the wind lab, and the other for the ocean currents lab) challenge students to apply what they have observed to wind and ocean currents in a way that contributes to a deeper understanding of these Earth systems.
