Earth’s axial tilt and seasonal changes help Grade 6 students explain why sunlight, daylight hours, temperatures, and seasonal conditions change throughout the year. This Alberta-focused Sky Science worksheet connects Earth’s tilted axis and yearly orbit around the Sun to familiar seasonal patterns, including warmer Alberta summers, reduced snow cover, and changes in plant and animal behaviour.

From Sunlight Angle to Seasonal Temperature

Students explore how Earth’s axis is tilted approximately 23.5 degrees and how this orientation affects incoming sunlight. When a region tilts toward the Sun, sunlight arrives at a higher angle and is concentrated over a smaller area. Longer daylight hours also allow more solar energy to reach the region over the course of a day. During winter, lower-angle sunlight and shorter days reduce incoming solar energy.

Examples from Alberta help students connect these ideas to local conditions. They consider why summer often brings warmer temperatures and less snow cover, while winter typically brings shorter days and lower-angle sunlight. The reading also introduces biological rhythms, showing how seasonal changes in daylight and temperature can influence plant growth, animal activity, feeding, and migration.

Scientific Reading, Reasoning, and Application

The worksheet moves from an informational passage to activities that ask students to retrieve evidence, recognize relationships, and explain seasonal patterns. Students practise the following skills:

• Multiple-choice questions: Identify the cause of seasonal changes, interpret sunlight angles, connect daylight duration with seasonal conditions, and explain the role of Earth’s yearly orbit.
• True-or-false statements: Evaluate claims about axial tilt, sunlight distribution, Alberta’s summer and winter conditions, and biological rhythms.
• Short-answer responses: Explain why Alberta can be warmer in summer, describe changes in received solar energy, and give examples of seasonal effects on living things.
• Labeled diagram: Apply visual reasoning to the relationship between Earth’s tilt and seasonal sunlight.
• Categorization and short-note writing: Organize key ideas and consolidate understanding of the lesson.

What Is Included

• Grade 6 Science worksheet focused on axial tilt and seasonal changes.
• Separate PDF answer key for checking responses.
• Student Notes lines at the bottom of the worksheet for recording key concepts and lesson summaries.
• Teacher Guide included in the Answer Key PDF, with Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes.

Practical Uses in a Sky Science Unit

Use this seasonal changes worksheet for guided reading, independent practice, lesson review, or a check of student understanding during an Alberta Grade 6 Sky Science unit. The local examples give students a concrete way to relate an astronomical concept to weather patterns and living things they may observe throughout the year. The separate answer key supports response checking, while the teacher guidance provides prompts for discussion and helps address common misconceptions about why seasons occur.

Rather than treating summer and winter as temperature differences alone, students investigate how axial tilt changes sunlight angle and daylight duration. This resource helps connect Earth’s movement in space with observable seasonal patterns and the ways organisms respond to changing environmental conditions.
