How does light travel?

• in scattered pieces that spread out the light

• in wavy lines that create sound as they move

• in straight lines, unless it bends or bounces off a surface

• in fast or slow movements depending on the temperature

A flat mirror reflects an exact yet reversed image of an object. In contrast, what kind of image does a convex surface like the outside of a spoon reflect?

• a distorted image

• a larger image

• a discolored image

• no image at all

Read the following sentences from the text: "The speed of light isn't always the same. It actually slows down when it moves through some transparent materials, like glass or water. When light slows down, it changes direction. This 'refraction' of light is the reason a straw in water looks bent or broken and why objects viewed through a glass bottle appear distorted. In the same way light reflects differently off different surfaces, it also refracts differently depending on the shape of the material. This can make refraction very useful. For example, the curve of eyeglasses directs light rays into the eyes more effectively. Magnifying lenses also use refraction: the convex lens bends the light rays so the image appears larger." What conclusion can you draw from this evidence?

• A magnifying glass reflects light rays in parallel paths because it has a flat surface.

• A curved glass can cause refraction because of both its shape and transparency

• Eyeglasses work like mirrors because they show an exact image in reverse.

• If a straw in water looks bent or broken, then you should use another straw.

How is reflection related to the colors of everything we see?

• The colors of the things we see depend on the speed at which the light moves off of each surface.

• The colors of the things we see depend on the shapes of the material that the light is reflecting off of.

• The colors of the things we see depend on what materials the objects are made of and whether or not they are transparent.

• The colors of the things we see depend on which wavelengths of light get reflected and which ones get absorbed.

What is the main idea of this text?

• The Moon does not have light of its own but we can see it from Earth because the Sun's light reflects off of its surface.

• Light is a form of energy that affects the way we see the world through reflection and refraction.

• Magnifying lenses use refraction by using a convex lens to bend light and make small things appear larger.

• Different types of electromagnetic radiation have different wavelengths and include radio waves, microwaves, ultraviolet rays, and X-rays.

What are adaptations?

• small rodents that are the size of chipmunks and eat hay

• behavior or physical characteristics that help animals survive

• shoes that you need to wear when you visit a snowy place

• a place with warm and damp weather all year around

Hibernation slows down an animal's body processes. According to the text, how does this affect its survival?

• It helps its survival because they can run faster to find food.

• It hurts its survival because they cannot escape other animals.

• It helps its survival because they need very little food energy.

• It hurts its survival because they stay in one place for months.

Read the following sentences from the text: "Migration is not just for the birds. Some mammals, including caribou and some kinds of bats, also migrate. In summer, these caribou feed and raise their young in northern Alaska and Canada. Then they travel south, as far as 800 miles to forests that are somewhat protected from the arctic winter." What conclusion can you draw from this evidence?

• The caribou hibernate after they migrate 800 miles to the forests because they are

  tired.

• Only young caribou migrate south for the winter because they do not have fur to stay

  warm.

• Winter in northern Alaska and Canada is colder than winter in the forests the caribou

  migrate to.

• Caribou and bats migrate south from northern Alaska and Canada to the same

  forests.

How have the snowshoe hare and ruffed grouse adapted similarly to cold weather?

• They grow hair on their feet that helps them walk on the snow.

• They slow down their heart-beat so they use little food energy.

• Their fur or feathers turn white to help them hide in the snow.

• They migrate to forests that are protected by cold temperatures.

What is the main idea of this text?

• Trees hibernate in their own way during the winter because they appear dead and protect young leaves from drying out.

• Some animals, like chipmunks and woodchucks, hibernate in the winters while other animals, like bears and skunks, are less active.

• The pika is a rodent that makes winter food for itself by cutting stems of grass, drying them out, and storing them in rocks.

• As the climate in North America changed, plants and animals adapted in different ways to survive during cold weather.
