Compare daylight records

Compare daylight records using supplied evidence and a solved model.

About 12 minutes, plus any extended practice

Supplied materials

For younger learners, an adult may read each direction aloud; pointing, drawing and spoken explanations count as responses.
Paper, drawing space or a browser document.
Reference card A: more daylight hours in the supplied record. Reference card B: fewer daylight hours in the supplied record.
Assessment case 1: Which scientific label fits the specifically described step or feature? Supplied case: Record A twelve hours, B ten: A.
Assessment case 2: Which scientific label fits the specifically described step or feature? Supplied case: A nine hours, B eleven: A.
Assessment case 3: Which scientific label fits the specifically described step or feature? Supplied case: A ten hours, B ten: A.
Assessment case 4: Which scientific label fits the specifically described step or feature? Supplied case: A says warm but gives no times.
Assessment case 5: Which scientific label fits the specifically described step or feature? Supplied case: A thirteen hours, B twelve: A.
Assessment case 6: Which scientific label fits the specifically described step or feature? Supplied case: A eight hours, B nine: A.

Learn the idea

Sunrise and sunset records let us compare daylight. A longer daylight interval is not the same as a hotter daily temperature. Supplied clock durations need no outdoor observing.

Longer means more daylight hours in the supplied record. Shorter means fewer daylight hours in the supplied record. Equal means same daylight hours. Unknown means record does not give daylight duration.

For longer, look for the clue “more daylight hours in the supplied record.” For shorter, look for “fewer daylight hours in the supplied record.” More than one process can happen in a real situation. Answer about the one described in this question.

Read or listen to the four science words and what each means. Say how the first two differ.
Choose two of the short cases. Point to the clue that helps you choose a science word for each one. You may draw or say your answer.
Answer each practice question. Say which clue helped you, then check the explanation.
Use the extra task to make two examples that show different science words. Draw or say what makes each one fit.

Worked example

See the method in action

Worked reference-card problem: a card states “more daylight hours in the supplied record”; a second states “fewer daylight hours in the supplied record.” The first fits longer and the second fits shorter. The reason is the described function or change, not the order of the cards or a favorite name. If their descriptions exchange places, their category labels exchange too. Keep the supplied descriptions attached to the correct case.

Helpful tips

Use the feature “more daylight hours in the supplied record” to justify longer; do not sort by the name alone.
Distinguish shorter (fewer daylight hours in the supplied record) from a different process occurring in the same situation.

See the answer and explanation

longer

The answer is longer. In the notes, it means “more daylight hours in the supplied record.” Sunrise and sunset records let us compare daylight. A longer daylight interval is not the same as a hotter daily temperature. Supplied clock durations need no outdoor observing.

Take it further

Create one new case showing longer and one showing shorter. Expected: the first explicitly shows “more daylight hours in the supplied record”; the second explicitly shows “fewer daylight hours in the supplied record.” Explain the distinction by drawing, speaking or writing. A label without a matching feature is incomplete.

More practice: try new cases

Choose an answer for each problem. Explain your method on paper, then use the feedback to decide what to revisit.

Need a hint?

Look for the described feature: fewer daylight hours in the supplied record.
Compare the clue with each science word. Use only what the case tells you; do not add a new event.

2. Which scientific label fits the specifically described step or feature? Supplied case: A ten hours, B ten: A.unknownlongershorterequal

Need a hint?

Look for the described feature: same daylight hours.
