Fishy hands

On Monday room 7 got a fish. We decided to do 3 experiments. 1st we estimated the weight of the fish. My estimation was eleven kgs. Take a guess at the weight. Next we did a stinky hand experiment. Mr Marquand picked 8 people to rub there hands all over the fish then stand by a container. There were different things to wash our hands in. There was fresh water, soap, baking soda, salt, detergent, toothpaste, vinegar and lemon juice. Then we made a hypothesis. My hypothesis was detergent after our hypothesis the tester smelt the volunteers hands then the volunteers washed there hands then the testers smelt there hands again. Coming up in 1st place was detergent with 9/10, 2nd place soap with 8/10, 3rd toothpaste with 6/10 4th vinegar with 5/10. This was a great experiment. These results might not be true because of the smell on the hands and the testers. Mr Marquand cut up three pieces of fish to see which will last the longest. One has salt one hade lemon juice and one just plain. they are now sitting on the window and were waiting for results.
