For those who have seen our latest feature doc, OBSERVER, one image likely lingers in your mind: the red square. It’s a striking symbol for observation, utilized in the film as a framing device to focus one’s gaze and highlight the hidden wonders all around us. It’s also a great classroom tool to use in conjunction with our free K-12 activity guide or lesson plans.
