AI Slide Tools: When Two Answers Are Right

In this evaporation example, two options fit the question: the water level gets lower, and some water becomes vapour. The teacher’s edit needs to make one specific idea the focus. Here is a complete passage, tool request and question revision to work through.

Deck.Toys has Questions Generator and Reading Leveler inside the Slide editor. The April feature article shows the available tools. Start with a passage you are happy to teach, then give the tool one specific job.

Start with the idea you want to check

For ages 9–10, the teaching goal here is: water vapour is still water, in a different state. This passage is ready to use on a Slide:

A shallow, open dish holds water. Water cannot pass through its sides or base. We mark the water level and leave the dish in a warm room. No water is spilled. The next day, the level is lower. Some liquid water has changed into water vapour and moved into the air. This change is called evaporation. Water vapour is water in its gas state; the water has not become a different substance. Evaporation can happen without the water boiling.

The science follows the USGS explanation of evaporation: liquid water changes to gaseous water and moves into the atmosphere.

Choose Questions Generator and try this narrow request:

For ages 9–10, write one multiple-choice question based only on this passage. Check what happens to water during evaporation, rather than how quickly it evaporates. Give three options with exactly one correct answer and explain the key. Keep the terms evaporation and water vapour.

Read every option as if it might be right

Start with this question and check each option against the passage.

What happens to the water in the dish?

• A. The water level gets lower.
• B. Some water becomes water vapour in the air.
• C. The water changes into a different substance.

A and B are both supported by the passage. A describes the observation; B explains the change. Even if you intended B as the key, a pupil choosing A has not said anything false. C is wrong, but one wrong option does not rescue an ambiguous question.

Here is the teacher-edited final question:

What has happened to the water that left the dish by evaporation?

• A. It passed through the base of the dish.
• B. It changed from liquid water to water vapour in the air.
• C. It changed into a new substance that is not water.

Key: B. Its state and location changed, but it is still water. A contradicts the detail about the dish's base. C contradicts the explanation of water vapour.

Follow the choice with: “Which words in the passage rule out A and C?” Expect pupils to identify “Water cannot pass through its sides or base” and “water in its gas state” or “has not become a different substance.” That short explanation helps you distinguish a reasoned choice from a guess.

Simplify the sentences, keep the science

If the passage is too dense for your readers, try Reading Leveler with this instruction:

Use shorter sentences. Keep evaporation and water vapour, and explain both terms. Keep the facts that water cannot pass through the dish and that water vapour is still water. Do not add new facts.

Compare the result with your original. Check that it retains the key terms and facts. Here is a shorter version:

Water is in an open dish. Water cannot pass through the dish. None is spilled. Later, the water level is lower. Some liquid water has changed into water vapour in the air. Water vapour is water as a gas. This change is called evaporation. The water is still water.

Both versions support the same final question and key. “The water went away” would be shorter, but it would remove exactly the idea this question is meant to check.
