5th Grade Light STAAR Review

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, causing objects to appear shifted from their actual position.

Front

Why do lenses refract light?

Back

Lenses refract light because they are made of transparent materials that change the speed of light as it passes through them.

Front

What is the main function of a microscope?

Back

The main function of a microscope is to magnify small objects so that they can be seen in greater detail.

Front

How does light travel?

Back

Light travels in straight lines until it encounters a medium or an obstacle.

Front

What happens to light when it hits a reflective surface?

Back

When light hits a reflective surface, it bounces back, a process known as reflection.

Front

What is the difference between transparent, translucent, and opaque materials?

Back

Transparent materials allow light to pass through completely, translucent materials allow some light to pass but scatter it, and opaque materials do not allow any light to pass through.

Front

What is the purpose of the objective lens in a telescope?

Back

The objective lens in a telescope refracts light to gather and focus it, allowing distant objects to appear closer.

Front

Why does a fish appear closer to the surface when viewed from above water?

Back

A fish appears closer to the surface due to the refraction of light as it passes from water to air, bending the light rays.

Front

What is reflection?

Back

Reflection is the bouncing back of light when it hits a surface, allowing us to see images.

Front

What is a medium in the context of light?

Back

A medium is any substance through which light travels, such as air, water, or glass.
