Our science experiment was about water as liquid and how when water molecules meet air they are pulled together tightly because they are meeting air molecules.
We had water drop races using coloured water, wax paper and straws. We looked at the shape of the water drops and as we raced had to keep them together.
Understanding that surface tension makes drops of water the shape they are.
Surface Tension is important as it captures dust particles, allows insects to walk on water and is integral in the upward movement of sap in plants.
