Malachi uses some glue to fix a broken plate. He puts the glue under a desk lamp but the glue doesn’t dry. Then he puts the glue out in the sun and it dries. Why does light from the sun dry the glue when light from the desk lamp does not?

• Because the glue can take in energy from the light from the sun but not from the light from the lamp.

• Because light from the sun pulls energy out of the glue and light from the desk lamp does not.

• Because the sun gives off a type of light that carries energy, and light from the desk lamp does not.

• Because light from the sun carries heat molecules, and light from the desk lamp does not.
