Chime Lab lesson plans
Each one is a class period with everything to run it: a teacher plan, a student worksheet, an exit ticket with answers, and the standards it meets. Students need no account, and a free class saves their work.
Chime Lab: Same Bounces, Different Mood
Eight pegs around a ring play one octave of C, and two balls bounce off them. Students switch the scale from Major to Minor and back while it plays: the balls bounce exactly the same way, but the music changes mood. They find out which notes changed, compare five scales with words for how each one feels, count how many notes each scale has, and then set up a ring to fit a mood card, record a take, and have a partner guess the mood.
On Teachers Pay TeachersChime Lab: Which Peg Gets Hit Most?
If eight pegs were hit equally often, each would get one eighth of the hits: 12.5 percent. Students guess, then let three balls bounce for a minute while the app counts. The bottom peg gets about three quarters of all the hits and the top five almost none. They roll new luck and run again, plot the class's results, and find the share barely moves: a long-run relative frequency they can use as a probability. Then they hunt for the one setting that makes the pegs close to fair, and explain why gravity, kick and bounciness cannot do it but a turning ring can.
