Last week Science Club members had to find out which white powder had been “accidentally” mixed with the powdered milk. First members had a good look at all the white powders and recorded what they looked/felt like. The next step was to add water to each powder and note the reaction. Next, vinegar was added to the powder and any reaction was noted.
Members then tested the contaminated mixture with both vinegar and water to look for similarities. As health salts fizzed up with both water and vinegar, while chalk only fizzed up with the vinegar, it was concluded that it was the health salts that had been mixed with the milk powder. Well done Science Club!! You are great detectives.
