question: Complete the sentence. Cracks forming in concrete due to changes in temperature is a ().

choice: (A) chemical change (B) physical change

gold answer: B

wrong prediction:

Rationale:

0: Matter is made of very small particles called atoms.
1: Atoms can be linked together by chemical bonds.
2: When two or more atoms link together, they form a molecule.
3: In a chemical change, the chemical bonds in the molecules break.
4: The atoms then link together to form new molecules.
5: The types of molecules in matter before and after a chemical change are always different.
6: Burning a piece of paper is a chemical change.
7: As paper burns, paper molecules react with oxygen molecules in the air.
8: This reaction breaks the chemical bonds in the molecules.
9: The atoms then relink and form different molecules.
10: For example, carbon dioxide molecules are created when paper burns.
11: In a physical change, chemical bonds do not break.
12: The types of molecules in matter before and after a physical change are always the same.
13: A change of state is a type of physical change.
14: For example, water vaporizing is a physical change.
15: Liquid water and water vapor are made of the same type of matter: water.
16: Concrete hardening is a chemical change.
17: The chemicals in the concrete react with each other to form a different type of matter.
18: Over time, concrete can break down.
19: Cracks forming in concrete due to changes in temperature is a chemical change.
20: The temperature changes cause the chemicals in the concrete to react with each other.
21: This reaction forms a different type of matter, which causes the concrete to break down.
22: The answer is A.

question: Which solution has a higher concentration of pink particles?

choice: (A) Solution A (B) neither; their concentrations are the same (C) Solution B

context: The diagram below is a model of two solutions. Each pink ball represents one particle of solute.

gold answer: B

wrong prediction:

Rationale:

0: A solution is made up of two or more substances that are completely mixed.
1: In a solution, solute particles are mixed into a solvent.
2: The solute cannot be separated from the solvent by a filter.
3: For example, if you stir a spoonful of salt into a cup of water, the salt will mix into the water to make a saltwater solution.
4: In this case, the salt is the solute.
5: The water is the solvent.
6: The concentration of a solute in a solution is a measure of the ratio of solute to solvent.
7: Concentration can be described in terms of particles of solute per volume of solvent.
8: concentration = particles of solute / volume of solvent In Solution A and Solution B, the pink particles represent the solute.
9: To figure out which solution has a higher concentration of pink particles, look at both the number of pink particles and the volume of the solvent in each container.
10: Use the concentration formula to find the number of pink particles per milliliter.
11: Solution A has more pink particles per milliliter.
12: So, Solution A has a higher concentration of pink particles.
13: 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 magnetic force is weaker in Pair 2. (B) The strength of the magnetic force is the same in both pairs. (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: 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: 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.
11: The answer is C.
