Investigating Heat and Melting

Observe How Heat Changes Matter

Find different solids (like chocolate, butter, and ice) and see what happens when you warm them gently.

Steps

  1. Place each item on a small plate.
  2. Use a sunny window or a lamp for gentle heat.
  3. Watch and record which items melt, and how fast.

This experiment shows how heat energy can change the state of matter!

Examples

  • Chocolate melts in your hand faster than ice melts on a table.

  • Butter gets soft and runny when left near a warm stove.
