Today's show is all about perspective or how we see objects in space. Perspective is the technique of representing three dimensional objects on a two dimensional space - like drawing a house on a flat piece of paper. It's all a point of view from which we categorize or measure - like a tree that gets smaller and smaller as we walk away from it. Our first example is an optical treasure box with geometric patterns. Next, build your own kaleidoscope. Add to your art journal - how perspective makes buildings and other city scenes more realistic. Finally, make a lightweight ball with streamers and watch it fly through the air and learn about perspective.
