Fair Testing

This half term in science we have been learning about scientific enquiry and all the steps you need to take when conducting experiments. We conducted a coin cleaning experiment to see which substance was best for cleaning dirty coins. We had to make sure we kept everything the same apart from the substance to ensure our test was fair. We also had to make sure we wrote out our method and equipment accurately to ensure the experiment could be accurately repeated. We had so much fun finding out which was the most effective! Ask us which substance worked best to clean the coins!!
