For STEM Week, we were given a secret question to reveal and investigate. Our question was: “What is living on our hands?”
To investigate this, we first set up an experiment where we exposed slices of bread to different things: hands washed in soap and water, hands washed with sanitiser only, unwashed hands and an iPad screen. The bread is now sealed in bags and left for us to observe what happens. We will update you with our findings.
Next, we watched a video about what is living on our hands and looked at some photos of different micro-organisms taken under a microscope.
Finally, we took part in a hand washing experiment to see how well we wash our hands compared to how well we think we wash our hands!
