Substance Prediction ResultsManganese Dioxide 3 4 Substance started to bubble and smokeSand 2 0 No Reaction

Potato 3 1 Slow Reaction, Minimal bubblingLiver 3 3 Moderate reaction, gradual bubblin over top

Used Liver/New Peroxide 4 2 Starte to slowly bubble to the top of the tubeNew Liver/Used Peroxide 3 1 Very minimal bubbling, slow reaction

Crushed Liver 3 3 Started fizzing very fast, large bubblesCrushed Potato 3 1 Slowly bubbles and fizzed, small bubbles

Boiled Liver 2 0 No reactionWarm Peroxide 4 4 Bubbled very quickly, overflowedCool Peroxide 2 3 Moderate reaction, large bubbles
