The explanation: Wind pushes golf ball down the pipe (gravity)  Golf ball hits a box and ricochets to hit domino’s (gravitational)   Domino’s hit each other and hits the string holding the hammer up (potential/kinetic)  The hammer falls on the button (gravity)   The electricity passes through the circuit when the button is pressed and sings a song (electricity/sound)   https://myriverside.sd43.bc.ca/sophian2019/files/2020/10/Riverside-CCs-Self-Assessment-Document-science.docx
