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.
-
-
After VideoHow can you slow down the melting of a popsicle?ANSWER
-
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.
-
