My child studied water surface tension by getting a steel pin to float on the water

Science

• The child learned about water surface tension and how it allows certain objects, like a steel pin, to float on the water.
• They discovered that the surface tension is caused by the cohesive forces between water molecules.
• The child observed how the surface tension can be disrupted by adding substances like soap, causing the pin to sink.

For continued development, you can encourage the child to explore other objects that can float on water and investigate the factors that affect surface tension, such as temperature or the presence of impurities.
