Earth–Sun geometry and seasonal daylight take centre stage in this Grade 6 Science worksheet, where students explore how Earth's axial tilt and changing orbital position influence apparent solar positions, daylight duration, and seasonal sky patterns. Using predictive models, learners practise making scientific predictions and checking them against observations of the real sky.

Set in the context of Alberta's northern latitude, this resource connects abstract Earth–Sun relationships with a familiar seasonal pattern: summer generally brings longer daylight and higher midday solar angles than winter. Students examine how a model represents the arrangement and motion of Earth and the Sun, what information can be changed, and what predictions can be made from those inputs.

Explore Earth–Sun models and seasonal changes

The worksheet develops scientific reasoning around several connected ideas:

• Axial tilt and daylight: explain why Earth's tilted axis matters when predicting seasonal differences in sunlight.
• Solar angle and apparent position: connect Earth's position and orientation with the Sun's apparent position in the sky.
• Model inputs and predictions: distinguish changes made to a model from the results the model predicts.
• Prediction and observation: compare model-based expectations with observations of sunrise, sunset, daylight duration, and seasonal sky patterns.
• Physical and diagram models: consider how a globe, light source, marked orbit, and diagrams can represent relative motion and orbital position.

What students do

Students read a science passage before applying the ideas through multiple-choice questions, true-or-false statements, short-answer explanations, a labeled diagram, a categorization activity, and a short note. The tasks ask learners to identify useful model components, interpret the meaning of solar angle, predict whether daylight will increase or decrease, and explain why observations are needed to evaluate a model.

Rather than treating a model as an exact copy of the sky, students consider how it can simplify a system to support qualitative predictions. This gives them practice separating the information supplied to a model from the conclusion drawn from it, an important part of scientific modelling and evidence-based reasoning.

Included with the worksheet

• ✔️ Printable Grade 6 Science worksheet focused on Earth–Sun geometry and predictive models
• ✔️ Separate answer key PDF for checking student responses
• ✔️ Student Notes lines at the bottom of the worksheet
• ✔️ Teacher Guide within the Answer Key PDF, including Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes

Practical classroom use

Use this seasonal daylight worksheet during a Sky Science lesson, as guided practice after introducing Earth's axial tilt, for independent review, or as a check of students' ability to interpret and evaluate models. The reading passage provides a shared starting point, while the written explanations and diagram-based tasks give students opportunities to demonstrate their reasoning in different ways.

Designed for Grade 6 Science with Alberta identified as the curriculum framework, this resource combines content review with prediction, model interpretation, and observation-based thinking. The separate answer key and included teacher guidance also make it easier to check understanding and address common misconceptions about seasonal daylight and scientific models.
