choice: (A) water flea (B) black crappie (C) water mold
context: Below is a food web from Little Rock Lake, a freshwater lake ecosystem in Wisconsin.
A food web models how the matter eaten by organisms moves through an ecosystem. The arrows in a food web represent how matter moves between organisms in an ecosystem.
gold answer: A
wrong prediction:
Rationale:
- 0: A food web is a model.
- 1: A food web shows where organisms in an ecosystem get their food.
- 2: Models can make things in nature easier to understand because models can represent complex things in a simpler way.
- 3: If a food web showed every organism in an ecosystem, the food web would be hard to understand.
- 4: So, each food web shows how some organisms in an ecosystem can get their food.
- 5: Arrows show how matter moves.
- 6: A food web has arrows that point from one organism to another.
- 7: Each arrow shows the direction that matter moves when one organism eats another organism.
- 8: An arrow starts from the organism that is eaten.
- 9: The arrow points to the organism that is doing the eating.
- 10: An organism in a food web can have more than one arrow pointing from it.
- 11: This shows that the organism is eaten by more than one other organism in the food web.
- 12: An organism in a food web can also have more than one arrow pointing to it.
- 13: This shows that the organism eats more than one other organism in the food web.
- 14: Primary consumers eat producers.
- 15: So, in a food web, primary consumers have arrows pointing to them from producers.
- 16: The water mold has arrows pointing to it from the green algae and the water flea.
- 17: Neither the green algae nor the water flea is a producer, so the water mold is not a primary consumer.
- 18: The black crappie has an arrow pointing to it from the water flea.
- 19: The water flea is a producer, so the black crappie is a primary consumer.
- 20: The water flea has an arrow pointing to it from the green algae.
- 21: The green algae is a producer, so the water flea is a primary consumer.
- 22: The rotifer has an arrow pointing to it from the water flea.
- 23: The water flea is a producer, so the rotifer is a primary consumer.
- 24: The answer is B.

gold answer: A
wrong prediction:
Rationale:
- 0: Magnets can pull or push on other magnets without touching them.
- 1: When magnets attract, they pull together.
- 2: When magnets repel, they push apart.
- 3: These pulls and pushes are called magnetic forces.
- 4: Magnetic forces are strongest at the magnets' poles, or ends.
- 5: Every magnet has two poles: a north pole (N) and a south pole (S).
- 6: Here are some examples of magnets.
- 7: Their poles are shown in different colors and labeled.
- 8: Whether a magnet attracts or repels other magnets depends on the positions of its poles.
- 9: If opposite poles are closest to each other, the magnets attract.
- 10: The magnets in the pair below attract.
- 11: If the same, or like, poles are closest to each other, the magnets repel.
- 12: The magnets in both pairs below repel.
- 13: To predict if these magnets will attract or repel, look at which poles are closest to each other.
- 14: The north pole of one magnet is closest to the south pole of the other magnet.
- 15: Opposite poles attract.
- 16: So, these magnets will attract each other.
- 17: The answer is B.
