Refraction is the bending of light rays as they enter a new material.
A spectrum is the series of colored bands that are created when sunlight is separated.
A material that does not allow light to pass through it is opaque.
Light always travels in a straight line.
Material that allows light to pass through, but you cannot see objects on the other side of it is
translucent.
White light is a mixture of colored lights.
An object is black when all of the colors of the spectrum are absorbed by an object.
A blue sky appears blue because the sky is reflecting blue light.
Thomas Edison invented the electric light bulb.
The Eye:
1. The cornea is the transparent layer covering the front of the eyeball.
2. The retina is the light-sensitive lining covering the inside of the eyeball.
3. The lens is the structure behind the pupil that refracts and focuses the light it receives.
4. Tapetum an extra layer of reflecting cells behind the retina that is found in many nocturnal
animals.
5. The muscles that regulate the size of the pupil are found in the iris.
6. The pupil is the opening that allows light to enter the eye.
7. The optic nerve is the large bundle of fibers that carries the message of what the eye has seen to
the brain.
8. Binocular vision is the type of vision in which both eyes work together to produce an image of
the same object.
Concave
1. A mirror which bulges away from the viewer and makes things look bigger.
2. A lens which scatters light rays is concave.
3. Sir Isaac Newton’s reflecting telescope used a concave mirror and a convex lens.
4. Be able to identify a concave lens.
Convex
1. A mirror which bulges toward the viewer and makes things look smaller.
2. A lens which refracts light rays and brings them into focus is a convex lens.
3. Be able to identify a convex lens.
The colors of the spectrum: red, orange, yellow, green, blue, violet
Insects:
1. An example of camouflage is when an insect blends in with its surrounding.
2. A nymph is a young insect that looks exactly like the adult
3. A beetle is an insect with a straight line down its abdomen and has chewing mouth parts
4. When insects move from place to place with the changing seasons, they are migrating
5. A male bee is called a drone.
Mammals:
1. Animals which eat meat are called carnivores
2. Rodents are the largest group of mammals
3. A nocturnal animal is an animal that is active only at night
4. The odor of the skunk is produced by its musk glands
5. An animal is considered extinct when their species no longer exist
6. Animals that chew their cud are considered ruminants
7. Whales and dolphins have a layer of blubber instead of fur
8. The echidna and the platypus are egg-laying mammals
9. Primates include the chimpanzees, gorillas and monkeys
DISCUSSION:
Explain the importance of insectivores as part of God’s plan for maintaining the balance of nature. Be
able to answer this using 3-4 complete sentences.
