Nancy cannot find her favorite shoes in the back of her dark closet. She grabs a flashlight and sees them! Why couldn't she find them before she turned on the flashlight?
Nancy cannot find her favorite shoes in the back of her dark closet. She grabs a flashlight and sees them! Why couldn't she find them before she turned on the flashlight?
Tap to reveal answer
Nancy could not see her shoes in the dark closet because humans cannot see when there is no light. The light must shine on an object and reflect into our eyes for us to see the object clearly, or it must make its own light. Shoes cannot make their own light, and the back of the closet was too dark for her to see.

The word illuminate means to light something up. Humans have good vision, but we do not see well at night because there is limited light. Our eyes rely on light to reflect off the surface of an object so that we can see.

Which choice would be the BEST to illuminate a dark room?
Tap to reveal answer
The best choice to illuminate (or light up) a dark room would be a lantern. A radio would give off little to no light, and a small candle would only produce enough light to see a few inches ahead of you. A lantern would give off much more light and help you to see in the dark.

A glow stick produces its own light. You can use a glow stick to illuminate a small dark area or to make yourself more easily seen at night time. Glow sticks make their own light when two chemicals are mixed after snapping or shaking the stick.

Bobby's teacher placed a secret object in a cardboard box and taped it closed. She poked small holes in the sides with a pen. She asked Bobby to look inside and tell her the secret object.

Tap to reveal answer
Bobby couldn't see in the box because it was too dark! Tiny pinholes are not big enough to let enough light inside the box. If Bobby were to make larger holes or more holes, it would allow more light in to illuminate the object.

The best object to bring into a cave would be the fire torch. This would illuminate or light up the area around you so that hidden objects (or dangers) would be visible. In the dark, without any light source, we would not know what is up ahead.
