You know that friction also causes heat. Think about when you rub your hands together. It is friction that makes them warm. But why does this happen? Friction causes the molecules on rubbing surfaces to move faster. Faster moving particles have more heat energy. Heat from friction can be useful. Can you think of other places where you might find friction? Friction also lets you light a match. Heat from friction can also cause problems. It can cause a car to overheat. To reduce friction, oil is added to the engine. Oil coats the surfaces of moving parts. This coating of oil makes them slippery. When things are slippery there is less friction. Have you ever seen a sign that says, slippery when wet? This too has to do with friction. Water, like oil, can reduce friction. The wet surface may allow your shoes to slide more easily.

Question: "How does oil reduce friction between moving car parts?"

Answer: "It coats the surface of the moving parts, making them slippery, which reduces the friction"

Response: yes

Assisting Zionist causes Einstein was a figurehead leader in helping establish the Hebrew University of Jerusalem, which opened in 1925, and was among its first Board of Governors. Earlier, in 1921, he was asked by the biochemist and president of the World Zionist Organization, Chaim Weizmann, to help raise funds for the planned university. He also submitted various suggestions as to its initial programs. Among those, he advised first creating an Institute of Agriculture in order to settle the undeveloped land. That should be followed, he suggested, by a Chemical Institute and an Institute of Microbiology, to fight the various ongoing epidemics such as malaria, which he called an "evil" that was undermining a third of the country's development. Establishing an Oriental Studies Institute, to include language courses given in both Hebrew and Arabic, for scientific exploration of the country and its historical monuments, was also important. Chaim Weizmann later became Israel's first president. Upon his death while in office in November 1952 and at the urging of Ezriel Carlebach, Prime Minister David Ben-Gurion offered Einstein the position of President of Israel, a mostly ceremonial post. The offer was presented by Israel's ambassador in Washington, Abba Eban, who explained that the offer "embodies the deepest respect which the Jewish people can repose in any of its sons". Einstein declined, and wrote in his response that he was "deeply moved", and "at once saddened and ashamed" that he could not accept it.

Question: "What position did Einstein decline, though he was "saddened and ashamed" not to accept it?"

Answer: "Israel's ambassador in Washington"

Response: no

Is this an insect or an animal? A snail is an animal just like you and me. Thats right, you too are an animal. No, you don't look like a snail. You do have some things in common. Animals can be divided into many groups. These groups are decided based on their characteristics. All animals have some basic features in common. That does not mean they are the same. They also have many differences. For example, snails are mollusks and not insects. Mollusks have a unique set of features. Notice the large foot that allows it to move. Yes, it only has one foot. Did you notice the long antennas on its head? This is where the snail's eyes are. They are on the end of the antenna. They are not on its head like most animals. The foot and eyes are unique features. Scientists use these features to place animals into groups.

Question: "Name one identified difference between snails and insects."

Answer: "Snails have eyes on the antennae whereas insects have them on the head"

Response:
yes
