Read the passage and answer the two questions at the end. Restate each question and use proper punctuation.
Jack and Jill are at the park collecting rocks. Every time they find a rock, they toss it into their red wagon. After some time, they fill their wagon and begin pulling it back to their house. When they get to a curb, they realize they can no longer lift the wagon over because it is too heavy from all the rocks. They look around, trying to figure out what to do. They notice two wooden boards on the side of their neighbors house.
- What simple machine can they make with the two wooden boards?
- How will it make their work easier?
They can make a simple machine called an inclined plane with two wooden boards. The inclined plane will make their work easier because they can push the wagon up a ramp.
