Our local Health Nurse visited Piwakawaka Last week. Stephanie talked to us about washing our hands properly so we can aviod catching viruses. Before we eat we need to santise or wash our hands. We all lined up in groups to practice washing our hands. Stephanie had sprayed some pretend virus on them, then we washed and dried our hands. Stephanie then checked using an ultra violet light to see how clean our hands actually were. THe Ultra violet light shows germ areas as white and the claen areas purple.
When it wasn't our turn we watched some Nano Girl videos our viruses and how to stop them sticking to our skin. There was a very simple experiment where you float cinnimon or pepper on a bowl of water. First you dip your finger in the water and all the 'germs' stick to the skin. then you drop a couple of drops of dish degerent into the water and watch as it repels the 'germs'. This shows us we need to use soap. Wateris not enough to clean our hands.
