Exploding cells! – By John Dietz and Nicola Morris

It’s good to get outside and tear up a few weeds, but sometimes a more scientific approach is needed. Invasive plants are very stubborn, and some will just grow back no matter how many times you pull them up by the roots.

SINNG volunteers, who are also trained STEM ambassadors, showed pupils from four Primary Schools how we can use chemicals to control invasive non-native plants. These plants cause impacts to the environment, the economy, our health and the way we live. The workshops, held as part of the Chemistry at Work event at the Sterts Theatre, nr Liskeard, had a huge turnout with approximately 85 children from Upton Cross Delaware, Gunnislake and Pensilva Primary schools taking part.

Children took part in an experiment to demonstrate the effects of chemicals on plant cells using zip lock bags and effervescent tablets. The results were explosive! The day was a huge success and enjoyed by all who took part, a teacher quoted “This is the best school trip they have been on”.
