Third grade hosted a NASA Ames Research Center scientist last week to further their study of light and electromagnetic energy.
Thanks to AVS mom Linda Shipley, the third grade students were given a fascinating presentation on the electromagnetic spectrum. Students were encouraged to act out how changing electric and magnetic fields together create waves on two different planes. Moreover, myriad images (e.g., flowers, faces, animals, foods) were shown under ultraviolet and infrared light compared to visible light.
Students were given the opportunity to see through an infrared camera before and after the scientist "drew" on their faces with an otter pop (popsicle in plastic). Various materials (e.g., foam board, clear hard plastic, opaque plastic bag) were held up in front the camera to demonstrate that infrared light allows us to see things in opaque form when they appear transparent under visible light. Students also learned that their fingers can become a tool for drawing by using their own heat as ink.
