Order a repeating sky pattern

Order a repeating sky pattern 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: daylight begins in this simplified record. Reference card B: middle part of daylight interval.
Assessment case 1: Which scientific label fits the specifically described step or feature? Supplied case: First daylight event.
Assessment case 2: Which scientific label fits the specifically described step or feature? Supplied case: Middle daylight event.
Assessment case 3: Which scientific label fits the specifically described step or feature? Supplied case: Final daylight event.
Assessment case 4: Which scientific label fits the specifically described step or feature? Supplied case: Dark interval between days.
Assessment case 5: Which scientific label fits the specifically described step or feature? Supplied case: Next event after this model’s night.
Assessment case 6: Which scientific label fits the specifically described step or feature? Supplied case: Next interval after sunset.

Learn the idea

Repeated observations help describe cycles. A pattern may help predict a next observation but does not replace careful observation. Our four-label cycle is a simplified model.

Sunrise means daylight begins in this simplified record. Midday means middle part of daylight interval. Sunset means daylight ends in this simplified record. Night means time after sunset before sunrise.

For sunrise, look for the clue “daylight begins in this simplified record.” For midday, look for “middle part of daylight interval.” 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 “daylight begins in this simplified record”; a second states “middle part of daylight interval.” The first fits sunrise and the second fits midday. 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 “daylight begins in this simplified record” to justify sunrise; do not sort by the name alone.
Distinguish midday (middle part of daylight interval) from a different process occurring in the same situation.

sunrise

The answer is sunrise. In the notes, it means “daylight begins in this simplified record.” Repeated observations help describe cycles. A pattern may help predict a next observation but does not replace careful observation. Our four-label cycle is a simplified model.

Take it further

Create one new case showing sunrise and one showing midday. Expected: the first explicitly shows “daylight begins in this simplified record”; the second explicitly shows “middle part of daylight interval.” Explain the distinction by drawing, speaking or writing. A label without a matching feature is incomplete.

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

1. Which scientific label fits the specifically described step or feature? Supplied case: Middle daylight event.sunrisemiddaysunsetnight

Need a hint?

Look for the described feature: middle part of daylight interval.
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: Final daylight event.sunsetnightsunrisemidday

Need a hint?

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

3. Which scientific label fits the specifically described step or feature? Supplied case: Dark interval between days.middaysunsetnightsunrise

Need a hint?

Look for the described feature: time after sunset before sunrise.
Compare the clue with each science word. Use only what the case tells you; do not add a new event.
