A group of Year 5 and 6 primary students were invited to Camborne Science and International Academy recently for a day of extraordinary scientific experiments using a bowl of fruit.
“This was a fantastic workshop, seeing students learn how to turn pieces of fruit into fully functional batteries” said Lucy Gourley, Teacher of Science at CSIA. “They had not experienced anything like it before, and they were absolutely fascinated from start to finish!”
Students discovered all about acidic and alkaline solutions through an array of practical activities. “By using a bunsen burner and the technique of filtration, our group turned a red cabbage into a natural indicator. They used the colour change of their indicator to identify different types of solutions to help them learn which types of fruit were most acidic” said Lucy.
Using this knowledge, students were able to predict whether a kiwi, lemon or orange would generate the most potential to produce the best battery to power an LED.
“The fruity batteries the students made consisted of two different metal electrodes and a fruit of their choice, and the look on their faces was priceless as they discovered how the process worked.”
Students then planned and carried out a fair test to investigate which type of fruit produced the greatest voltage. “At the end of the session, with everyone’s fruity batteries joined with wires in a circuit, the group were able to successfully light up an LED. At this point, the whole room cheered with excitement!”
“Our Super Saturday Workshops are fun, educational and inspirational” added Lucy. “We’re allowing students to physically experience the concepts they’re learning about in the classroom, which helps them to retain information and remember more effectively.”
“Delivering core learning in ways which engage our children is very important, giving them extensive practice in what it means to think like a scientist” added Principal at CSIA, Ian Kenworthy. “Practical activities like this one with exciting outcomes boost engagement and generate a real buzz around learning and understanding.”
