About this activity

A live class lab: phones predict whether each substance dissolves, the big screen tests it in a glass tank and dives into the particles, and the class explains it with the charged ends of water particles, then applies the pattern to new jars and to the universal solvent.

What students learn

  • Predict whether everyday substances dissolve in water, then check with a fair test that changes only the substance
  • Explain dissolving with the particle view: water particles have charged ends that pull on and surround the particles of many substances
  • Explain why oil and sand do not dissolve, and why dissolving is not melting and does not make a substance disappear
  • Explain why water is called the universal solvent: it dissolves more substances than any other common liquid, but not all
