Today, Class 2 conducted a fair test to see which liquid cleans coins the best. We kept the amount of each liquid the same and the variable was the type of liquid. We tested tomato ketchup, washing up liquid, vinegar, lemon juice, mouthwash and toothpaste. We tested our liquids to see how acidic they were using universal indicator pape. We found out that vey acidic substances clean metals really well. Well done Class 2. Great science work today!
