In the dropping water on a coin experiment, children observed the fascinating behaviour of water droplets as they formed bubbles before bursting to release water. To conduct this experiment, we gathered flat coins, a small cup of water, and a dropper. First, we asked the children to predict how many drops of water could fit on the coin’s surface without spilling over. Using the dropper, they allowed them to carefully add drops of water one at a time onto the coin, counting each drop. Encouraged discussions about why the water stays on the coin and the concept of properties of water. This hands-on activity not only engages their curiosity but also enhances their fine motor skills.
