"Cartesian Divers" Trailer

Students create a chamber with a small "creature" inside that will dive to the bottom or rise to the top seemingly by magic. This relates to properties of matter, liquids, gases, air pressure, and compressibility of air versus water. This video also includes one of Mr. Mac’s crazy stories, “Jack and Jill on the Moon,” to help students remember the lesson. Difficulty: Easy
