You might want to know how cold it is. You may need to know how fast the wind is blowing. Maybe it rained last night? Do you know how much? Does it feel humid to you? You have heard all these questions before. To answer these questions, we need data. That data comes from special tools. These tools collect data about the weather. You can see some of the common tools listed below: A thermometer measures temperature. An anemometer measures wind speed. A rain gauge measures the amount of rain. A hygrometer measures humidity. A wind vane shows wind direction. A snow gauge measures the amount of snow.

Question: "How can you find out how much snow fell in a particular time frame?"

Response: "Rain gauge"

A: no

The properties of matter depend on the types of atoms that matter is made of. Matter can exist in two forms. It can be a pure substance. This means it is not mixed with anything. It can also be a combination of different substances. This means it can be a mix of different types of atoms. You may recall that atoms differ based on the numbers of protons they contain. Some atoms contain only one proton such as Hydrogen. Other atoms contain many protons. There are many types of atoms. For example, Helium has two protons. An Oxygen atom has eight. Water is composed of a two types of atoms. Water is made of two Hydrogen atoms and one Oxygen atoms. There are only so many types of atoms. These atoms can be mixed into an almost limitless amount of substances. So what do we call a substance that has only a single type of atom?

Question: "How many protons do atoms contain?"

Response: "Some atoms contain only one proton such as Hydrogen. Other atoms contain many protons"

A: yes

The side of Malaquez's parcel gave way to reveal a greenmunk caught in a sheen of solid air. Bits of leaf mold flew from under his feet as he ran to greet a friend or a bringer of food. Tasha oohed in awe. I said, "Frodo's been visiting you, eh?" Malaquez said, "Your pet?" "Hardly. He lives around here somewhere. I suppose he was attracted to the commotion up the hill." "Ah," Malaquez said. "Why 'Frodo'?" Tasha said, "A little fellow with big, furry feet. What else could he be called?" She handed the sculpture to me. I almost dropped it; I expected it to weigh no more than a holo. "Heavy," I said, as if he might not have known. He laughed. "My last piece was of four old Undersiders crouched around a trash fire. Be glad someone didn't toss that to you." He spoke of his art with the enthusiasm of a seven-year-old. "Um, I should wait to importune you, but..."

Question: "Is the sculpture heavy?"

Response: "Not at all"

A:
no
