Investigating Microbes.

As part of Year 6’s Science lessons about living things (particularly microbes), and to celebrate the festival of Halloween, we investigated the decomposition of fruit using pumpkins. We designed our own ‘fair test’ style investigation to see how we could preserve the pumpkins for Miss Dockey’s Halloween parties. First, we completed a full risk assessment of the investigation and decided we needed to wear goggles and gloves to prevent any toxic substances touching our skin. After this, when we were sure we could be safe, we carved our pumpkins and painted a fine coating of a liquid (water, yoghurt, bleach, lemon juice, milk or vinegar) around the inside of our pumpkin. I wonder which pumpkin will survive?
