Can you smell something fishy

On Monday Mr M brought an Australasion snapper fish to school. It weighed 12 kgs and was 82cm long. Mr M cut it up and put 3 peices into 3 diffrent jars he added salt to one, lemon juice to one and left one with nothing. We are currently watching them.

We had some volunteers come up and rub there hands on the fish. Then they washed there hands with the testing product.(salt, detergent, tothpaste, vinegar, soap, baking soda, lemon juice and plain water). Most people thought vinegar would win but suprisingly it was detergent that won.
