Sunlight Warms the Earth

Before Video

• Things feel warmer when they are in the sun; your clothes, your hair, inside a car, etc.

• You might have used shade at a picnic or at a baseball game. There are many occasions where you might have tried to find shade to protect you from the sun.

• You can use trees, canopies, big hats or tents for shade. Many different things can be used for shade.

• The black top, metal surfaces or dark colored things heat up faster than things that are lighter colored or made of plastic or wood.

• You can use a thermometer, which is a tool that measures temperature.

• Popsicles melt, ice cubes melt and chocolate melts, too. When anything changes from a solid to a liquid we say it has melted.

• You can move to a shady area, so that the sunlight can’t heat up the popsicle.

• Sunlight heats up the surface to make it hot enough to cook an egg.

• You can use a thermometer to measure the temperature of different materials over time.

• Thicker things and things that are not see through are better sources of shade. For example, a curtain provides more shade than a window.

• The ice cube in the box has shade. This slows down the melting process.

• The Earth has many surfaces such as water, grass, sand, soil and snow.
