Writes Mr Goddard, Outdoor Learning & Science Teacher
In Science, Year 6 pupils recently put their laboratory skills to the test with a hands-on chemistry investigation to discover which everyday foods contain starch. Building on their understanding of food substances and carbohydrates, the boys explored how scientists can use simple chemical tests to identify the different components found in the foods we eat.
Armed with dropper bottles and iodine solution, the boys carefully tested a selection of food samples, applying a few drops of iodine to each one and observing what happened. They looked closely for a colour change, learning that iodine turns from its usual orange-brown colour to blue-black when starch is present. This provided a clear visual indication of which foods contained starch and which did not.
Throughout the investigation, the boys had to work carefully and methodically, ensuring that they applied the solution accurately and observed each sample closely. They compared their results, discussed their findings and considered what the colour changes revealed about the composition of different foods. The activity encouraged them to make predictions, test their ideas and use evidence from their observations to draw scientific conclusions.
It was a fantastic opportunity for Year 6 to put their scientific knowledge into practice while developing their practical laboratory techniques, attention to detail and observational skills. By carrying out their own chemical tests, the boys gained a greater understanding of how scientists investigate the properties of everyday materials and how simple experiments can reveal fascinating information about the food we eat!
