3. Take turns in reading to the group the article “Why are bees vanishing?”
4. As you read gather evidence that supports the 3 main causes of colony collapse disorder (CCD) suspected by scientists. Write the various evidence in the corresponding columns below:
PARASITES PESTICIDES INFECTION
5. After reviewing the evidence you have gathered, explain which one of the three is the main cause of CCD.
6. Explain whether your hypothesis (#2) is correct or not and explain why:
7. Write your conclusion about why bees are vanishing.
8. Knowing what you know about CCD, describe the actions people should take to help avoid CCD.
9. Explain why is it important to keep a healthy population of bees. Also, describe or draw a scenario wherein there are no more bees in the United States.

Native (in ecology)
Colony A group of organisms that live close together or share a home (such as a hive or other
Enzyme Molecules made by living things to speed up chemical reactions.
Genus (plural genera) A group of closely related species. For example, the genus Canis —
which is Latin for “dog” — includes all domestic breeds of dog and their closest wild relatives,
including wolves, coyotes, jackals and dingoes.
Herbicide A chemical used to kill weeds.
honeybee A stinging, winged insect that collects nectar and pollen, and produces wax and
honey. Honeybees live in large groups called colonies. Each colony consists of a queen, who
lays all eggs, and her offspring. These consist of male drones, but mostly large cadres of female
“worker” bees that attend to the hive and its inhabitants and forage for food.
Insecticide A chemical used to kill insects.
mite A small, eightlegged
creature related to spiders and ticks. It is not an insect.
Mushroom body The part of a bee’s brain involved in learning, memory and navigation.
Native (in ecology) An organism that evolved in a particular area and continues to live there.
Navigate To find one’s way between two points.
Neonicotinoids A class of insecticides usually applied to target pests such as aphids, whiteflies
and some beetles. These insecticides, called neonics for short, can also poison bees.
Neuroscience Science that deals with the structure or function of the brain and other parts of
the nervous system. Researchers in this field are known as neuroscientists.
Neurotransmitter A chemical substance that is released at the end of a nerve fiber. It transfers
an impulse or signal to another nerve, muscle cell or some other structure.
ornamental plants Shrubs and other plants, including many prized for their blooms or showy
leaves and berries.
Pesticide A chemical or mix of compounds used to kill insects, rodents or other organisms
harmful to cultivated plants, pet or livestock, or that infest homes, offices, farm buildings and
other protected structures.
Pollinate To transport male reproductive cells — pollen — to female parts of a flower. This
allows fertilization, the first step in plant reproduction.
Pollinator An animal that transfers pollen from one flower to another, allowing the plant to grow
fruit and seeds.
Solitary Living alone.
