A greenhouse is a building that protects plants from the cold but allows them to still get sunshine. Which type of material would be the best choice for building a greenhouse?

• a transparent material because it allows some of the light to shine through

• a translucent material because it allows most of the light to shine through

• a transparent material because it allows most of the light to shine through

• a translucent material because it allows some of the light to shine through

The picture shows Rhonda's science fair poster. Rhonda created her poster based on her knowledge of transparent, translucent, and opaque objects. Rhonda made a mistake on her poster. What was her mistake, and how can it be corrected?

• She described translucent and opaque materials incorrectly. All light can shine through translucent materials, but no light can shine through opaque materials.

• She described opaque and translucent materials incorrectly. Some light can shine through opaque materials, but no light can shine through translucent materials.

• She described transparent and translucent materials incorrectly. All light can shine through transparent materials, but some light can shine through translucent materials.

• She described translucent and transparent materials incorrectly. No light can shine through translucent materials, and some light can shine through transparent materials.

• The mirror is broken.

• The mirror is hung upside down.

• The light hitting the mirror reflects back in the opposite direction.

• The light that hits the mirror in a straight line reflects back in curves.

Josh is investigating what happens in a dark room when he turns on his flashlight and passes the light beam through the room. What will most likely happen if the light beam reaches a mirror?

• The light beam will be reflected by the mirror and bounce back toward him.

• The light beam will be refracted by the mirror and bounce back toward him.

• The light beam will be reflected by the mirror and continue in the same direction.

• The light beam will be refracted by the mirror and continue in the same direction.

A student places a pencil in a glass of water and observes the image through the water. What is happening to light that makes the pencil appear to be bent or broken?

• Light is being reflected.

• Light is being refracted.

• Light is being absorbed.

• Light is being spread out.

When light enters a prism, it

• increases in speed.

• refracts and bends.

• reflects off the surface.

• continues in a straight line.

Stacey is investigating the sound a rubber band makes when you stretch it to different lengths and pluck it. How can Stacey best describe the rubber band when it makes sounds that have a low pitch?

• It vibrates slowly and makes sound waves that are far apart.

• It vibrates quickly and makes sound waves that are far apart.

• It vibrates slowly and makes sound waves that are close together.

• It vibrates quickly and makes sound waves that are close together.
