Observe objects in darkness when illuminated - 1st Grade Science

This statement is true. Objects cannot be seen if it is dark. There has to be light from an outside source, or the object has to produce its own light to be seen.

The light must reflect off the surface and enter the eye to be seen. An object will not be seen in darkness because there is no light reflecting off of the object's surface.

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.

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 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.

Lightning bugs use their internal light source to attract other insects. They might eat the other bugs that come to visit them, or if they are from the same species, they may become mates.

These beautiful oriental fish lanterns are visible in the dark because there is a light source inside of them illuminating the darkness. Humans must have light to reflect off of an object's surface for our eyes to process the image.

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.
