    Using Context Clues Lesson 15

    You can use context clues to figure out the meaning of an unfamiliar word. The chart below gives examples of different types of context clues.

    Type of Clue Example

    Definition Superfoods, or natural foods that may prevent disease, have become popular.

    Cause/Effect Some superfoods, such as blueberries and red beans, contain antioxidants. These can help remove harmful substances from the human body.

    Comparison Some experts look dubiously on claims about superfoods, but other experts believe strongly that these foods can improve health.

    Context clues can also help you figure out words with more than one meaning. For example, the table below has two sentences with the word source. What does source mean in each sentence? You can use the underlined context clues to figure out which meaning of source is being used.

    Sentence Context Clues Definition

    Choosing high-sugar drinks can be a source of health problems.

    A problem has a cause. Therefore, the source of a problem is its cause.

    the cause of something

    The website MyPlate.gov is a source for facts about food choices.

    A website can have information such as facts. Therefore, a source is something that gives information.

    something that gives information

    The sentences before and after the sentence with an unfamiliar word can also hold context clues.

    Introduction

    Some fads are fleeting, but more than a few people feel that

    superfoods are here to stay. The idea of superfoods isn’t new, but the

    amount of empirical information we have about them is. Scientific

    observations and tests offer some evidence that certain foods can

    help people stay healthy. Nobody claims that these foods are

    a panacea—nothing can guarantee perfect health or cure every

    disease—but they can be part of a sensible diet.

    Determine the meanings of fleeting, empirical, and panacea. Then underline the words or phrases that helped you determine their meaning.

    Guided Practice

    HINT The phrases as a result of, because of, and thanks to all signal cause-and- effect relationships. Words such as but, too, also, and as well as all indicate comparisons.

    LAFS.5.L.3.4a: Use context (e.g., cause/effect relationships and comparisons in text) as a clue to the meaning of a word or phrase.

    Big Birds, Big City

    World Almanac for Kids

    Some peregrine falcons have moved to New York City.

    Walk around New York City, and you may see some people looking skyward in awe. They might be admiring the city's high-rise buildings, or they might be admiring peregrine falcons instead.

    These majestic birds of prey, which were on the verge of extinction, have made a comeback across the United States. Some have even moved to New York City. The falcons aren't alone in calling the Big Apple home. Bald eagles have also moved into the neighborhood.

    Death by DDT Peregrine falcons are the fastest creatures in the air. They can chase their prey at speeds of up to 200 miles per hour.

    The birds were nearly wiped out in the 1960s from exposure to a pesticide called DDT. A pesticide is a chemical designed to kill insects and other pests that damage plants and crops. Scientists didn't realize in the 1940s, 1950s, and 1960s that DDT also harmed birds and other animals.

    According to biologists, DDT made the eggshells of peregrines and other birds thin and fragile. The shells broke before the baby peregrine falcons were ready to hatch. By 1970, there were only 39 known nesting pairs of peregrine falcons in the lower 48 states.

    Road to Recovery The U.S. government banned DDT in 1972. A year later, Congress passed the federal Endangered Species Act. The law protected many animals that were in danger of dying out, including peregrine falcons.

    Today, more than 2,000 pairs of falcons nest nationwide, including at least 20 couples in New York City. The first two falcon pairs moved to the city in 1983.
