Question: Don wanted to find out if a battery powered toy truck would always travel the same distance in 10 seconds no matter how heavy a load the truck carried. He placed one or more blocks (the load) in the back of the truck and recorded his results. (Each block had the same mass.) The following graph displays his results. What is the relationship between the number of blocks and the distance traveled by the truck in 10 seconds?
Reference answer: The more blocks the truck carries, the less distance the truck travels in 10 seconds.

Student answer: As the number of blocks increases the distance decreases.

Student answer: As the blocks increase the distance decreases.

Student answer: The more blocks you put on the truck the farther it gets, in meters.

Student answer: As the number of blocks increases, the distance increase.

Student answer: The relationship is as the number of blocks increases the distance decreases.

Student answer: The more blocks the shorter the distance traveled.

Student answer: Once he added one more the mass was slower and that is what he showed on the graph.

Student answer: The distance goes up one every time also the number of blocks.

Student answer: It went farther with less blocks and it went no farther with more blocks.

Student answer: The relationship between the independent and the dependent variable is the more load the slower the truck will go.

Student answer: One shows the number of blocks and one shows the distance of how far they went.

Student answer: The more blocks the harder the truck tries to go faster causing it to go slower.

Student answer: Every time he put a block in it went 5 meters shorter.

Student answer: The more the block, the less it goes, the less the blocks, the farther it goes.

Student answer: The relationship is it goes down one every time you add a block.

Student answer: The relationship between the number of blocks and the distance traveled by the truck in 10 seconds is that they both change how far the truck goes.

Student answer: The relationship is that the less blocks the toy truck has the more it will carry and the more blocks the less it can carry.

Student answer: The relationship between the number of blocks and the distance is that it decreases every time and all of it decreases together.

Student answer: The relationship is that the more blocks that you put in the truck the less distance it will cover.

Student answer: The more blocks he puts in the truck the less the truck will travel.

Student answer: That it is increasing by the matter of seconds.

Student answer: The more number of blocks the less distance it goes or the less block the more distance.

Student answer: The number of blocks is measuring by meters.

Student answer: If the truck has less blocks it goes further.

Student answer: The more blocks you add the less distance it would go. It would have more mass.

Student answer: The more blocks Don added the slower the toy truck will go.

Student answer: That will more number of blocks the slower it goes.

Student answer: The distance of the meter is going lower. The number of blocks is going lower too.

Student answer: The distance of the meter is going lower. Number of blocks is getting lower too.

Student answer: The more blocks added the farther it went.

Student answer: The more blocks the less it goes.

Student answer: It goes up each one.

Student answer: The relationship is that each time he add a block it goes about one meter lower.

Student answer: The more blocks the less it will go.

Student answer: The more blocks it carried the less farther it would go.

Student answer: The more blocks the less meters it goes.
