Use two labeled positions, keep the axis parallel in both, and ask about a specified hemisphere. This original practice design pairs every diagram relationship with a complete text description, so learners do not have to guess from color or screen position alone.
NASA Space Place explains seasons through Earth's tilted axis and the changing directness of sunlight reaching the hemispheres. It describes opposite seasonal timing and the axis maintaining its direction during the orbit. It also notes that Earth is closest to the Sun during Northern Hemisphere winter, contradicting a simple “closer means Northern summer” explanation. NASA Space Place's seasons explanation
Label the two-position model before asking questions
The proposed schematic has a fixed Sun at the center. In panel J, Earth is left of the Sun. Its axis runs from southwest to northeast, with north at the northeast end. The north end tilts toward the central Sun; the south end tilts away. Sunlight arrows run from the Sun toward that Earth, from right to left.
In panel D, Earth is right of the Sun. Keep exactly the same southwest-to-northeast axis orientation, with north still at the northeast end. Here north tilts away from the Sun and south tilts toward it. Sunlight arrows run from the Sun to Earth, from left to right. Do not rotate the axis to make north point toward the Sun in both panels.
Use labels NJ and SJ for panel J's Northern and Southern Hemispheres, and ND and SD for panel D's. J is June-like and D December-like in this simplified model. Neither panel supplies an exact astronomical date, distance scale, or local temperature.
| Model position | Northern Hemisphere | Southern Hemisphere |
|---|---|---|
| J: Earth left; north tilted toward Sun | Summer | Winter |
| D: Earth right; north tilted away from Sun | Winter | Summer |
The companion keeps the full written panel descriptions beside the diagram. Selecting a panel and hemisphere in a proposed review view should reveal the corresponding written tilt relationship. Those views compare a schematic and its written tilt relationships; they are not an astronomical simulation.
Ask four bounded questions
Q1 asks: “In panel J, which season does the Northern Hemisphere represent?” Offer Summer and Winter; the teacher key is Summer.
Q2 asks: “In panel J, which season does the Southern Hemisphere represent?” Offer Summer and Winter; the key is Winter.
Q3 asks: “In panel D, which season does the Northern Hemisphere represent?” Offer Summer and Winter; the key is Winter. These three questions are bounded to the stated two-position model rather than a complete four-season calendar.
Q4 asks: “Which explanation matches this model?” Offer “Axial tilt changes how directly sunlight reaches the hemispheres” and “Northern summer occurs because Earth is closer to the Sun.” The first is the key. Keep the teacher key separate from unanswered learner choices.
If a learner selects Winter for Q1, a useful feedback message is: “In panel J, north tilts toward the Sun. This panel represents Northern summer and Southern winter. Check the hemisphere label as well as the position.” For the wrong explanation in Q4, point back to the unchanged axis and opposite hemispheres rather than merely displaying “incorrect.”
Give attempts a truthful state
The proposed worksheet has four unique item states. Unanswered is not the same as an attempted wrong answer. A check should identify unanswered items without awarding or subtracting points for them. Feedback follows the checked choice; changing that choice clears its old feedback before another check.
The correct-item count can never exceed four. Rechecking the same correct response does not earn another point. Retrying replaces that item's evaluated result rather than adding another scored item. Reset clears choices, feedback, and attempt state and returns to four unanswered questions.
These are expected local behaviors, not tests already performed. The count is practice feedback, not a saved grade or evidence of understanding beyond the selected answers. No scores are sent or collected in this design.
Leave local weather outside the model
End the discussion with “What would we need to know to describe the weather where you live?” The schematic does not provide local temperature or a weather forecast. Keep that question distinct from the hemisphere-season key, and do not invent irradiance measurements or day-length figures from the drawing.

Create one complete, self-contained US-English HTML companion for “Seasons lab • follow the tilt”. Return the full HTML document, with inline CSS and any JavaScript needed for the local interactions. Use the original scenario, named records, numbers and expected cases below.
Design the page for this task: use clearly labeled input or source records, a readable result or worked example, and an adjacent explanation of the evidence. Use a restrained visual hierarchy, left-aligned text, readable tables or stacked records, and a responsive layout at 720px and 360px. Provide meaningful labeled controls for J · North / NJ; J · South / SJ; D · North / ND; D · South / SD; Retry Q1; Retry Q2; Retry Q3; Retry Q4; Check my choices; Reset practice. Use keyboard-accessible native controls and visible focus. Keep the complete content readable without an external dependency.
The following brief supplies the substantive content and constraints. Native-format requests describe the material to represent or copy manually; this HTML must not pretend to create DOCX, XLSX, PDF, PPTX, H5P or another native file, run Python/Flask/Django/Snowflake/Power BI, connect a live service, send messages, or perform an authorized real-world action. Where the task requires a native source, actual observation or separate approval, retain that requirement and leave unsupplied evidence blank.
Create a complete US English seasons practice worksheet specification: original two-panel schematic description, full text alternative, four questions, separate teacher key, targeted feedback and local check/retry/reset test matrix. Keep expected checks separate from actual observations. Fixed Sun at center. Panel J: Earth left of Sun, axis southwest-to-northeast with north at northeast end; north toward Sun, south away. Sunlight arrows Sun-to-Earth, right-to-left. Panel D: Earth right of Sun, identical parallel axis orientation; north away, south toward. Arrows left-to-right. Labels NJ/SJ/ND/SD. Do not rotate either axis toward the Sun. J is June-like, D December-like; no exact date, distance or temperature scale. Q1 J north season: Summer. Q2 J south: Winter. Q3 D north: Winter. Options Summer/Winter, bounded to this model. Q4 correct explanation: axial tilt changes how directly sunlight reaches the hemispheres; wrong option: Northern summer because Earth is closer to Sun. D south is Summer in the text model. Explain opposite hemispheres and the distance misconception, with NASA source https://spaceplace.nasa.gov/seasons/en/ . No copied NASA illustration/activity. Include Q1 Winter feedback pointing to J north toward Sun and Southern winter. Four unique item states: unanswered is not attempted wrong; checking unchanged correct answers adds no points; retry updates that item; changing choice clears old feedback. Correct-item count at most4. Reset clears all choices,feedback and attempt state to unanswered. Separate teacher key from blank learner choices. Proposed panel/hemisphere selection shows the corresponding written tilt relationship. Full text and keyboard labels required; actual implementation/testing pending. No live planet positions, measured irradiance/day length, weather prediction, saved/sent scores or learner collection. Include a discussion question about what information local weather would need, without inventing that information.

# A Seasons Interactive Worksheet That Keeps the Tilt Consistent
A learner chooses “summer” because the picture puts Earth near the Sun. Another gets the Northern Hemisphere answer right but gives the Southern Hemisphere the same season. The worksheet needs a clear model and feedback that points to the relationship the learner missed.
Use two labeled positions, keep the axis parallel in both, and ask about a specified hemisphere. This original practice design pairs every diagram relationship with a complete text description, so learners do not have to guess from color or screen position alone.

Implement the local companion rather than returning a text-only plan. Preserve every numerical fixture and the distinction between illustrative expectations and actual evidence. Any native-runtime or classroom tests mentioned above remain tests to perform in the proper environment; do not mark them passed. Keep edits and practice responses in this open page only, without claiming persistent storage. Provide invalid/missing-input feedback and reset behavior that agree with this specific brief. Do not claim accessibility certification, learning gains, real approvals or test results that were not observed.
Review the model and key
Use the HTML companion to check that both axes retain the same orientation and that each answer follows the selected hemisphere in the companion. Keep actual learner work in the normal teaching workflow.
Finish with learners able to name the hemisphere and tilt relationship behind an answer, rather than treating a season label as a guess about Earth's distance from the Sun.
