Mixing Materials and Evidence of Change

Learners act as materials detectives: they identify substances by measured properties such as density, magnetism and solubility, then mix materials and look for evidence. Some mixtures can be separated again because each substance keeps its properties; other combinations make new substances, shown by gas bubbles, a new solid, a color change or a temperature change. A dissolving simulation and a sink-or-float simulation provide data, and each states what it cannot establish.

What learners will discover

  • Identify materials using measured properties such as density, magnetism, solubility and conductivity.
  • Explain that substances in a mixture keep their properties and can be separated, and investigate a factor that affects how fast a substance dissolves.
  • Use evidence such as gas, a new solid, a color change or a temperature change to decide whether mixing made a new substance.
