What with all the emphasis around hand hygiene and the spread of bacteria at the moment, we decided to set up an experiment in class to show the children the benefits of hand washing. We have not done this experiment before so are not sure of the results, but have made some sensible predictions.
The children reflected on their understanding of independent and dependent variables, as well as controls for fair test and planned an experiment using bread. They wanted to find out if it is better to use hand sanitiser (antibacterial gel) or to wash with soap and water. They each made a hypothesis about the results.
Feel free to pop into one of the year 3 classes to see our experiment in action. We look forward to sharing the results with you!
