Curated OER
Earth & Space Science: Holding it Together
Pupils estimate how many drops of water can fit onto the surface of a penny and then test their hypothesis to find out. They also experiment with bubbles.
Curated OER
Take a Dip: Sticky Water
Students complete lab activities to investigate the "sticky" properties of water, such as surface tension and capillary action, due to the polarity of the molecules.
Curated OER
Surface Tension On Coins
Students drop water onto clean coins to determine the tension of each coin and then to graph their findings.
Curated OER
Surface Tension-Driven Flows
Pupils learn how surface tension changes can cause fluids to flow.
