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: Which property do these three objects have in common?

choice: (A) colorful (B) bouncy (C) slippery

context: Select the best answer.

gold answer: B

wrong prediction:

Rationale:

0: An object has different properties.
1: A property of an object can tell you how it looks, feels, tastes, or smells.
2: Properties can also tell you how an object will behave when something happens to it.
3: Different objects can have properties in common.
4: You can use these properties to put objects into groups.
5: Grouping objects by their properties is called classification.
6: Look at each object.
7: For each object, decide if it has that property.
8: A slippery object is hard to hold onto or stand on.
9: The inflatable castle is not slippery.
10: A colorful object has one or more bright colors.
11: All three objects are colorful.
12: A bouncy object will bounce back from the floor if you drop it.
13: The rainbow sucker and the spring are not bouncy.
14: The property that all three objects have in common is colorful.
15: The answer is A.

question: Compare the average kinetic energies of the particles in each sample. Which sample has the higher temperature?

choice: (A) sample A (B) neither; the samples have the same temperature (C) sample B

context: The diagrams below show two pure samples of gas in identical closed, rigid containers. Each colored ball represents one gas particle. Both samples have the same number of particles.

gold answer: A

wrong prediction:

Rationale:

0: The temperature of a substance depends on the average kinetic energy of the particles in the substance.
1: The higher the average kinetic energy of the particles, the higher the temperature of the substance.
2: The kinetic energy of a particle is determined by its mass and speed.
3: For a pure substance, the greater the mass of each particle in the substance and the higher the average speed of the particles, the higher their average kinetic energy.
4: Each particle in sample B has more mass than each particle in sample A.
5: The particles in sample B also have a higher average speed than the particles in sample A.
6: So, the particles in sample B have a higher average kinetic energy than the particles in sample A.
7: Because the particles in sample B have the higher average kinetic energy, sample B must have the higher temperature.
8: The answer is C.

question: Would you find the word tidy on a dictionary page with the following guide words? thaw - trunk

choice: (A) no (B) yes

gold answer: B

wrong prediction:

Rationale:

0: Guide words appear on each page of a dictionary.
1: They tell you the first word and last word on the page.
2: The other words on the page come between the guide words in alphabetical order.
3: To put words in alphabetical order, put them in order by their first letters.
4: If the first letters are the same, look at the second letters.
5: If the second letters are the same, look at the third letters, and so on.
6: If one word is shorter, and there are no more letters to compare, then the shorter word comes first in alphabetical order.
7: For example, be comes before bed.
8: Put the words in alphabetical order.
9: Since tidy is not between the guide words thaw - trunk, it would not be found on that page.
10: The answer is A.

question: Based on the continuum scale, which of the following blood types is more common that B+?

choice: (A) B- (B) A+

context: This continuum scale shows how common different blood types are.

gold answer: B

wrong prediction:

Rationale:

0: A graphic organizer is a chart or picture that shows how ideas, facts, or topics are related to one another.
1: When you read, look for graphic organizers included in the text.
2: You can use these images to find key information.
3: You can also create your own graphic organizers with information that you've read.
4: Doing this can help you think about the ideas in the text and easily review them.
5: When you write, you can use graphic organizers to organize your thoughts and plan your writing.
6: A continuum scale compares things by ordering them along a line.
7: This continuum scale shows how common different blood types are.
8: Less common blood types are shown to the left.
9: More common blood types are shown to the right.
10: B+ is shown farther right than A+.
11: So, B+ is a more common blood type than A+.
12: The answer is A.

question: Which of the following best describes an ecosystem in the Great Lakes?

choice: (A) the water, the gravel, the snails, and the worms (B) a school of spotted gar (C) the lake sturgeon and the walleye

context: Read the passage. Then answer the question below. At the border between the United States and Canada, a series of lakes known as the Great Lakes forms the largest freshwater system in the world. The Great Lakes are home to several species of large fish, such as the spotted gar, the lake sturgeon, and the walleye. Lake sturgeon have sensory organs called barbels that hang down from their mouths. The sturgeon swim just above the rocks and gravel at the bottom of a lake. They use their barbels to search for prey including snails, mussels, and worms. Figure: a lake sturgeon with barbels under its mouth.

gold answer: A

wrong prediction:

Rationale:

0: In an environment, organisms interact with each other and with their nonliving surroundings.
1: To help describe these interactions, ecologists use specific terms for different types of groups.
2: A single organism is an individual.
3: Individuals of the same species that live in the same place are part of a population.
4: Multiple populations of different species that live in the same place are part of a community.
5: Together, communities of living organisms and the nonliving parts of their environment make up an ecosystem.
6: The answer is C.

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

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

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, but some of them are different shapes.

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 strength of a force is called its magnitude.
5: The greater the magnitude of the magnetic force between two magnets, the more strongly the magnets attract or repel each other.
6: You can change the magnitude of a magnetic force between two magnets by changing the distance between them.
7: The magnitude of the magnetic force is smaller when there is a greater distance between the magnets.
8: The magnets in Pair 2 attract.
9: The magnets in Pair 1 repel.
10: But whether the magnets attract or repel affects only the direction of the magnetic force.
11: It does not affect the magnitude of the magnetic force.
12: Distance affects the magnitude of the magnetic force.
13: When there is a greater distance between magnets, the magnitude of the magnetic force between them is smaller.
14: There is a greater distance between the magnets in Pair 2 than in Pair 1.
15: So, the magnitude of the magnetic force is smaller in Pair 2 than in Pair 1.
16: The answer is C.
