Main Idea and Supporting Details

Gravity is the force that makes things fall to Earth. You can't see or touch it, but without gravity, life on Earth would be quite different. Everything would simply float away. If you jumped up, you would fly off into space. If you threw a baseball, it would never come down. Gravity is also the force that keeps the Earth orbiting around the sun. So, without gravity, the Earth might float away too. Main Idea?

• The Earth will float away.

• Baseballs would never come down.

• Life on Earth would be different without gravity

• If you jumped up, you would float away.

It's hard to imagine what things were like before there was money, but such a time did exist. During these times people exchanged goods using the barter system. The word barter means to trade. People using the barter system traded things instead of buying and selling them. So if you were a rice farmer, you would trade your rice with many people to get all the things that you wanted or needed. Unfortunately, the people from whom you needed things might not want your rice. Isn't it nice to just go to the store and buy candy instead of having to trade rice for it?

True or false? The main idea is, "Before money existed, people used a barter system."

• True

• False

Being a clown isn't all fun and games. Rodeo clowns expose themselves to great danger every time they perform. When cowboys dismount or bulls buck them off, rodeo clowns jump in front of the bulls and motion wildly to get their attention. In this way rodeo clowns provide an alternate target, and in doing so protect the rider. Of course, this is a very dangerous thing to do. So you see, sometimes clowning around can be serious business. What is the main idea?

• Rodeo clowns expose themselves to great danger every time they perform.

• When cowboys dismount or bulls buck them off, rodeo clowns jump in front of bulls.

• Rodeo clowns protect the rider.
