On Monday we got to experiment on a fish. First we had to estimate how much it would weigh. Most of us estimated that it would wiegh about 5 kgs but it weighed a good 12 kgs. Then we had to guess how long it was. We all thought that it was 1 meter long but it was 84 cm long. Then we took a fillet out and
had a look at that. Once we had done that we did an experiment on what sort of substance would remove the smell of fish best.
The substances were lemon juice, baking soda, water, vinegar, toothpaste, salt, soap and detergent. All the people in the class thought that vinegar would be the best but detergent won.
