Lesson 18- Finding Information from Multiple Sources

Part A

What conclusion can you base on evidence found in both sources?

• All animals can use ultrasound and infrasound to communicate.

• Some animals use sounds to tell each otters about possible threats.

• Scientists continue to discover new ways that animals communicate.

• Body language is as important to elephant communication as sound is.

Part B

Choose one detail from each source to support the answer is Part A.

• "Their ears open up wide and appear to hear distinct sounds, and yet the humans observing the scene nearby hear nothing." ("Incredible Animal Ears")

• "These scientists concluded that the low sounds were actually warning sounds from another herd." ("Incredible Animal Ears")

• "So far, they have discovered 70 different sounds that they use for different situations." ("Incredible Animal Ears")

• "Sound travels in waves, and its pitch, or frequency, is measured in a unit that scientists call hertz." ("Animal Sounds")

• "Rats giggle at the ultrasound levels, and squirrels warn one another of danger by making high-pitched noises." ("Animal Sounds")

Part A

What main idea do both sources share?

• Humans can hear sounds that are between 20 and 20,000 hertz.

• Animals communicate with each other using sounds, many of which people cannot hear.

• Some animals communicate with high-pitched sounds called ultrasound; other animals use low-pitched sounds.

• Elephants use different sounds for different situations, such as signaling their location or a need for help.

Part B

Choose one detail from each source to support the answer in Part A.

• "Actually, the elephants are hearing a sound, but it has a pitch so low that humans can't detect it." ("Incredible Animal Ears")

• "Scientists continue to study the sounds that elephants make, and it's no easy task." ("Incredible Animal Ears")

• "Bees dance or emit smells to communicate with one another." ("Animal Sounds")

• "Yet, one of the most important ways animals communicate is by sound." ("Animal Sounds")

• "The lowest frequency a person can hear is 20 hertz (20 cycles per second)." ("Animal Sounds")
