Description: A 2x2 matrix categorizes silhouettes based on two axes: "Are Dinosaurs" vs "Are Not" and "Seem Like Dinosaurs" vs "Don't Seem Like." It contrasts prehistoric beasts, birds, and random objects. Transcript: [The image displays a 2x2 grid chart with column and row headers.] **Column Headers:** ARE DINOSAURS, ARE NOT DINOSAURS **Row Headers:** SEEM LIKE DINOSAURS, DON'T SEEM LIKE DINOSAURS **Top-Left Quadrant** *(Intersection: Are Dinosaurs / Seem Like Dinosaurs)* [Silhouettes of classic prehistoric dinosaurs: A Stegosaurus, a Triceratops, a Tyrannosaurus Rex, a large Sauropod (long-neck), and a smaller Raptor.] **Top-Right Quadrant** *(Intersection: Are Not Dinosaurs / Seem Like Dinosaurs)* [Silhouettes of prehistoric reptiles often mistaken for dinosaurs: A large marine reptile (Mosasaur), a standing Pterosaur (Azhdarchid), a flying Pteranodon, a long-necked Plesiosaur, and a sail-backed Dimetrodon.] **Bottom-Left Quadrant** *(Intersection: Are Dinosaurs / Don't Seem Like Dinosaurs)* [Silhouettes of modern birds (which are scientifically classified as avian dinosaurs): A penguin, a heron, an ostrich, a pigeon, and a flying seagull.] **Bottom-Right Quadrant** *(Intersection: Are Not Dinosaurs / Don't Seem Like Dinosaurs)* [Silhouettes of random objects and beings: A squirrel, a stapler, a pineapple, a human stick figure, and a bicycle.]

Miss Lenhart stands in front of a blackboard with a laptop in her hand, saying: Okay, middle school students, it’s the first Tuesday in February. This means that by law and custom, we must spend the morning reading through the Wikipedia article List of common misconceptions, so you can spend the rest of your lives being a little less wrong. The guests at every party you’ll ever attend thank us in advance. Caption: I wish I lived in this universe.

Description: A diagram on a black background shows a solid white circle. A drawn five-pointed star shape orbits it along a dashed elliptical path. Transcript: Panel 1: [A diagram on a black background. A solid white circle sits slightly off-center. A dashed line traces a large elliptical orbit around it. A simple five-pointed star icon is positioned on the orbital path to the right.] Caption: SPACE NEWS: ASTRONOMERS HAVE FOUND THE FIRST KNOWN SYSTEM WITH A MAIN-SEQUENCE STAR ORBITED BY A FIVE-POINTED ONE.
