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 dipped the stick in a dish filled with water and pepper . The pepper stuck (like microbes do to our hands when we touch anything). Finally, we dipped our stick in a bowl of washing up liquid and water. 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.
