During a 6th-grade science presentation, Maya explains the purpose of her talk: to teach classmates how the water cycle moves water through Earth's systems. She uses a slide deck, but most slides are long paragraphs that she reads aloud. She does include one small icon on each slide (a sun, a cloud, or a raindrop). When she describes evaporation, condensation, and precipitation, she does not include a labeled diagram or any video clip. Several students look confused when she talks about how water changes and moves, because the words alone do not stick with them. Maya also lists three numbers for average rainfall in three places (desert: 10 cm/year, grassland: 50 cm/year, rainforest: 200 cm/year), but she only says them out loud and keeps them in a sentence on the slide. She does not use any sound or music. Overall, her visuals mostly repeat her words instead of making the process easier to see.
In the presentation, which visual display would most help clarify the steps of the water cycle for the audience?
- A labeled diagram of evaporation, condensation, and precipitation, with arrows connecting each stage to show the order in which they happen (correct answer)
- A row of sun, cloud, and raindrop icons repeated on every slide, sized larger so the audience can see the pictures more clearly
- A detailed paragraph on each slide describing every stage in full sentences so the audience can follow along by reading each word
- A bar graph comparing the average rainfall of the desert, grassland, and rainforest so the audience can see the three amounts side by side
Explanation: The task asks which visual best clarifies the steps, or order, of the water cycle. A labeled diagram with arrows connecting evaporation, condensation, and precipitation is the best answer because it shows the stages in sequence, letting the audience actually see how one step leads to the next instead of just hearing the words. The row of larger icons is decorative: sun, cloud, and raindrop pictures may look nice, but they do not show the order of the process or how the stages connect. Making them bigger does not explain anything. A detailed paragraph on each slide has the same problem Maya already has—it repeats her spoken words in text, so it does not help students who cannot picture the process from words alone. A bar graph comparing rainfall amounts is a good visual for data, but it clarifies how much rain three places get, not the steps of the water cycle, so it answers a different question than the one asked.
