What Is Sunshine?

  • Sunshine is the bright light and warmth that comes from the sun.
  • It travels from far away in space to reach our planet Earth.
  • Sunshine is a natural source of energy that helps everything on Earth grow.

The Power of Heat

  • Sunshine is not just light; it also carries heat.
  • When the sun shines on an object, it transfers its heat to that object.
  • This heat is what makes the ground feel warm during a sunny afternoon.

What Is Melting?

  • Melting is what happens when a solid thing gets warm enough to turn into a liquid.
  • It occurs when heat is added to something that is frozen or very cold.
  • Melting is a change in the way something looks and feels.

How Sunshine Causes Melting

  • When sunshine hits something cold, like ice, the heat from the sun moves into the ice.
  • As the ice gets warmer, it cannot stay solid anymore and begins to turn into water.
  • The stronger the sunshine, the faster the melting happens.

Sunshine and Melting Examples

  • A snowman getting smaller and turning into a puddle on a sunny winter day.
  • An ice cube taken out of the freezer that turns into water on the counter.
  • Frozen juice popsicles that start to drip when you eat them outside in the sun.
  • Snow on the mountains turning into rushing water in the rivers when spring comes.

Lesson Summary

  • Sunshine provides the heat needed to change objects from cold to warm.
  • Melting is the process of a solid turning into a liquid because of heat.
  • Sunshine is the most powerful natural way to melt ice and snow in our world.
