question: Which of the following fossils is younger? Select the more likely answer.

choice: (A) crocodile egg (B) feather

context: This diagram shows fossils in an undisturbed sedimentary rock sequence.

gold answer: A

wrong prediction:

Rationale:

0: A fossil is the preserved evidence of an ancient organism.
1: Some fossils are formed from body parts such as bones or shells.
2: Other fossils, such as footprints or burrows, are formed from traces of an organism's activities.
3: Fossils are typically found in sedimentary rocks.
4: Sedimentary rocks usually form in layers.
5: Over time, new layers are added on top of old layers in a series called a rock sequence.
6: The layers in an undisturbed rock sequence are in the same order as when they formed.
7: So, the deeper layers are older than the shallower layers.
8: The relative ages of fossils can be determined from their positions in an undisturbed rock sequence.
9: Older fossils are usually in deeper layers, and younger fossils are usually in shallower layers.
10: Look again at the fossils in the rock sequence diagram.
11: Compare the positions of these fossils to determine which one is younger: The feather fossil is in a shallower layer in the rock sequence than the crocodile egg fossil.
12: So, the feather fossil is most likely younger than the crocodile egg fossil.
13: The answer is B.

2: The map's legend tells you the temperature that each color represents.
3: Colors on the left in the legend represent lower temperatures than colors on the right.
4: For example, areas on the map that are the darkest shade of blue have a temperature from -25°C up to -20°C.
5: Areas that are the next darkest shade of blue have a temperature from -20°C up to -15°C.
6: Look at the colors shown within the outlined area.
7: Then, use the legend to determine which air temperatures those colors represent.
8: The legend tells you that this air mass contained air with temperatures between 5°C and 20°C.
9: 10°C is within this range.
10: 5°C and 32°C are outside of this range.
11: The answer is B.

question: Will these magnets attract or repel each other?

choice: (A) attract (B) repel

context: Two magnets are placed as shown.

gold answer: B

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 south pole of one magnet is closest to the north pole of the other magnet.
15: Opposite poles attract.
16: So, these magnets will attract each other.
17: The answer is A.

question: Think about the magnetic force between the magnets in each pair. Which of the following statements is true?

choice: (A) The strength of the magnetic force is the same in both pairs. (B) The magnetic force is weaker in Pair 2. (C) The magnetic force is weaker in Pair 1.

context: The images below show two pairs of magnets. The magnets in different pairs do not affect each other. All the magnets shown are made of the same material.

gold answer: B

wrong prediction:

Rationale:

0: Magnets can pull or push on each other without touching.
1: When magnets attract, they pull together.
2: When magnets repel, they push apart.
3: These pulls and pushes between magnets are called magnetic forces.
4: The stronger the magnetic force between two magnets, the more strongly the magnets attract or repel each other.
5: You can change the strength of a magnetic force between two magnets by changing the distance between them.
6: The magnetic force is weaker when the magnets are farther apart.
7: Distance affects the strength of the magnetic force.
8: When magnets are farther apart, the magnetic force between them is weaker.
9: The magnets in Pair 1 are farther apart than the magnets in Pair 2.
10: So, the magnetic force is weaker in Pair 1 than in Pair 2.
