Autumn Equinox Activities & Fall Science Unit | Seasons & Daylight | Grades 1–3

Teach the Autumn Equinox with a complete Fall Science Unit designed for Grades 1–3. This 63-page printable resource helps students understand the equinox, Earth’s tilt, seasons, daylight patterns, hemispheres, fall weather, and seasonal changes through clear visual lessons, differentiated activities, hands-on investigations, data practice, and assessments.

Students move from simple concepts to deeper science thinking, making this unit easy to use across multiple grade levels.

What’s Included:

• Autumn Equinox vocabulary and visual science pages
• What Is an Autumn Equinox?
• Earth’s axis, rotation, orbit, and hemispheres
• What causes the seasons
• Science misconception: Earth’s tilt vs. distance from the Sun
• Daylight tables, graphs, and data analysis
• Sunrise and sunset observation activities
• Northern vs. Southern Hemisphere activities
• Fall weather observations and graphing
• Living things and seasonal changes
• Hands-on science investigations
• Claim, Evidence, Reasoning writing
• Grade 1 assessment
• Grade 2 assessment
• Grade 3 assessment
• Answer keys
• Teacher guide, pacing suggestions, and standards connections

The resource is intentionally differentiated so each grade level has age-appropriate practice:

Grade 1 focuses on vocabulary, basic equinox concepts, sorting, identifying patterns, and simple assessment questions.

Grade 2 builds understanding through cause and effect, daylight graphing, hemisphere comparisons, weather data, and application questions.

Grade 3 adds deeper analysis with daylight and weather data, hemisphere challenges, evidence-based reasoning, CER writing, and more advanced assessment questions.

This unit works well for fall science lessons, seasonal science units, whole-group instruction, small groups, science centers, homeschool learning, review, and sub plans.
