Stinky fish hands

We all know that getting fish smell off our hands can be difficult so we did an experiment to find out the best way to get the smell off our hands. We are learning about the scientific process and so are using this experiment to learn the process.

We tried water, soap, detergent, vinegar, toothpaste, baking soda, lemon and salt. Most people had a hypothesis that the vinegar would be the most effective. However, surprisingly, after the smell test it was the detergent that got the most votes. We will now talk about the variables in this experiment and if it was a fair test or not.
