Is it getting hot in here? Observe boiling from inside a beaker in an engaging interactive. Chemistry scholars heat and cool polar and non-polar solids and observe how molecules react to temperature changes. Your class' misconceptions about bonding are sure to evaporate!

Instructional Ideas

• Ask pupils to record their observations of the movement of both types of molecules as temperature increases and decreases
• For advanced classes, charge learners with the task of identifying the intermolecular forces that could be present in both substances, ranked by strength
  

Classroom Considerations

• Students should have prior knowledge of types of bonding and the Kelvin temperature scale before using the resource
  

Pros

• Quickly tracks the temperature changes using a Kelvin thermometer in the sidebar
• The interactive shows intermolecular forces at work throughout a temperature change from ~ 0K and 600K, making the interactive a great starting point for an intermolecular forces lesson
  

Cons

• None
