We have been working scientifically in science this half term and also learning about microbes, linked to preventing illness and cleanliness.
We used pepper in a test today to represent microbes.
We filled a dish with water. We put a stick in the water. It got wet!
We then added pepper to the water and dipped the stick in. The pepper stuck (like microbes do to our hands when we touch anything).
We finally rubbed washing up liquid on the stick. When we dipped it in the water again, the pepper moved away like magic! There was a gasp from everyone! This shows us that microbes (that sometimes make us ill) do not like soap and that is why we use it to wash our hands.
Why not give it a try at home?
