question: Will these magnets attract or repel each other?

choice: (A) repel (B) attract

context: Two magnets are placed as shown. Hint: Magnets that attract pull together. Magnets that repel push apart.

gold answer: A

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: Whether a magnet attracts or repels other magnets depends on the positions of its poles, or ends.
4: Every magnet has two poles, called north and south.
5: Here are some examples of magnets.
6: The north pole of each magnet is marked N, and the south pole is marked S. If different poles are closest to each other, the magnets attract.

7: It is missing a subject.
8: Who knows the answer?
9: She knows the answer.
10: The bright red car.
11: This is a sentence fragment.
12: It is missing a verb.
13: What did the bright red car do?
14: The bright red car stopped.
15: A run-on sentence is made up of two sentences that are joined without end punctuation or with just a comma.
16: I knocked on the door it opened.
17: It started raining, we ran inside.
18: To fix a run-on sentence, separate it into two sentences.
19: Add end punctuation after the first sentence, and capitalize the second sentence.
20: I knocked on the door.
21: It opened.
22: It started raining.
23: We ran inside.
24: You can also fix a run-on sentence by rewriting it as a compound sentence.
25: A compound sentence is two sentences joined by a comma and a conjunction such as and, but, or, or so.
26: I knocked on the door, and it opened.
27: It started raining, so we ran inside.

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

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

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: C

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 the two samples has the same mass, but the particles in sample B have a higher average speed than the particles in sample A.
5: So, the particles in sample B have a higher average kinetic energy than the particles in sample A.
6: Because the particles in sample B have the higher average kinetic energy, sample B must have the higher temperature.
7: The answer is B.

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.

question: Would you find the word softly on a dictionary page with the following guide words? seventh - sting

choice: (A) yes (B) no

gold answer: A

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 softly is not between the guide words seventh - sting, it would not be found on that page.
10: The answer is B.

question: Select the chemical formula for this molecule.

choice: (A) HO2 (B) H3O3 (C) H2O2 (D) H2O

gold answer: C

wrong prediction:

Rationale:

0: Every substance around you is made up of atoms.
1: Atoms can link together to form molecules.
2: The links between atoms in a molecule are called chemical bonds.
3: Different molecules are made up of different chemical elements, or types of atoms, bonded together.
4: Scientists use both ball-and-stick models and chemical formulas to represent molecules.
5: A ball-and-stick model of a molecule is shown below.
6: The balls represent atoms.
7: The sticks represent the chemical bonds between the atoms.
8: Balls that are different colors represent atoms of different elements.
9: The element that each color represents is shown in the legend.
10: Every element has its own abbreviation, called its atomic symbol.
11: Every chemical element is represented by its own symbol.
12: For some elements, that symbol is one capital letter.
13: For other elements, it is one capital letter followed by one lowercase letter.
14: For example, the symbol for the element boron is B and the symbol for the element chlorine is Cl.
15: The molecule shown above has one boron atom and three chlorine atoms.
16: A chemical bond links each chlorine atom to the boron atom.
17: The chemical formula for a substance contains the atomic symbol for each element in the substance.
18: Many chemical formulas also contain subscripts.
19: A subscript is small text placed lower than the normal line of text.
20: Each subscript in a chemical formula is placed after the symbol for an element and tells you how many atoms of that element that symbol represents.
21: If there is no subscript after a symbol, that symbol represents one atom.
22: So, the chemical formula for a substance tells you which elements make up that substance.
23: It also tells you the ratio of the atoms of those elements in the substance.
24: For example, the chemical formula below tells you that there are three chlorine atoms for every one boron atom in the substance.
25: This chemical formula represents the same substance as the ball-and-stick model shown above.
26: H is the symbol for hydrogen.
27: According to the legend, hydrogen atoms are shown in light gray.
28: O is the symbol for oxygen.
29: According to the legend, oxygen atoms are shown in red.
30: This ball-and-stick model shows a molecule with two hydrogen atoms and one oxygen atom.
31: The chemical formula will contain the symbols H and O.
32: There are two hydrogen atoms, so H will have a subscript of 2.
33: There is one oxygen atom, so O will not have a subscript.
34: The correct formula is H2 O.
35: The diagram below shows how each part of the chemical formula matches with each part of the model above.
36: The answer is D.

2: When magnets repel, they push apart.
3: Whether a magnet attracts or repels other magnets depends on the positions of its poles, or ends.
4: Every magnet has two poles: north and south.
5: Here are some examples of magnets.
6: The north pole of each magnet is labeled N, and the south pole is labeled S. If opposite poles are closest to each other, the magnets attract.
7: The magnets in the pair below attract.
8: If the same, or like, poles are closest to each other, the magnets repel.
9: The magnets in both pairs below repel.
10: To predict if these magnets will attract or repel, look at which poles are closest to each other.
11: The north pole of one magnet is closest to the south pole of the other magnet.
12: Opposite poles attract.
13: So, these magnets will attract each other.
14: The answer is A.
