Question 3: In an elementary classroom, a teacher introduces the water cycle. Which of the following correctly sequences the stages of the water cycle?
- Precipitation → Condensation → Evaporation
- Evaporation → Condensation → Precipitation (Correct answer)
- Condensation → Precipitation → Transpiration
- Runoff → Evaporation → Infiltration
Correct answer: Evaporation → Condensation → Precipitation
Water evaporates, rises and condenses into clouds, then falls as precipitation—the standard sequence of the water cycle.
Question 4: A teacher wants students to practice finding the main idea in informational texts. Which graphic organizer MOST directly supports this skill?
- Story map with characters and plot events

A main idea and supporting details web visually organizes the central topic and the evidence or examples that support it.
Question 5: A Missouri high school chemistry teacher is covering the periodic table. Elements in the same GROUP (column) share which property?
- The same number of protons
- The same atomic mass
- The same number of valence electrons (Correct answer)
- The same physical state at room temperature
Correct answer: The same number of valence electrons
Elements in the same group have the same number of valence electrons, giving them similar chemical properties.
Question 6: When teaching students about supply and demand in an economics unit, a teacher shows that prices rise when demand exceeds supply. This concept MOST directly relates to which economic principle?
- Opportunity cost
- Scarcity and market equilibrium (Correct answer)
- Command economy pricing
- Gross domestic product
Correct answer: Scarcity and market equilibrium
When demand exceeds supply, scarcity drives prices up until the market reaches equilibrium.
Question 7: A student reads the sentence: 'The scientist hypothesized that increased temperature would accelerate the reaction.' Which vocabulary strategy BEST helps a student determine the meaning of 'hypothesized'?
- Rereading the previous paragraph
- Using context clues from surrounding words and phrases
- Consulting a thesaurus
- Identifying the root word and affixes (Correct answer)
Correct answer: Identifying the root word and affixes
Breaking 'hypothesized' into its root 'hypothesis' and suffix '-ized' (to make/perform) reveals its meaning through morphemic analysis.
