Earth materials and Earth's interior science worksheets for Grade 7 help students investigate how scientists identify rocks and minerals and use evidence to explain what lies beneath Earth's surface. This Earth science resource develops careful observation, evidence-based reasoning, and an understanding of why scientific models are essential when direct investigation is limited.

From Mineral Properties to Earth's Deep Interior

Students begin with the differences between rocks and minerals, exploring observable properties such as colour, hardness, lustre, streak, and texture. They consider why colour alone cannot reliably identify a mineral and how consistent testing makes comparisons fairer. The lesson then moves underground, examining what drilling can reveal directly and how seismic wave measurements provide evidence about Earth's inaccessible regions.

Students connect changes in seismic wave speeds and paths to differences in materials and conditions. They investigate why scientists infer that Earth's outer core is liquid, distinguish observations from inferences, and consider how scientific models can change when new evidence becomes available. The reading also reinforces careful methods, open-mindedness, uncertainty, and respectful scientific communication.

What Students Practise

• Multiple-choice questions on rock and mineral definitions, mineral identification, drilling evidence, seismic waves, and Earth's outer core.
• True-or-false statements that address scientific testing, the limits of boreholes, evidence from seismic measurements, and the revisability of models.
• Short-answer responses explaining mineral identification methods, the benefits and limitations of drilling, and the difference between direct observations and scientific inferences.
• A labeled diagram activity and a categorization task that support visual organization and classification of lesson concepts.
• A short-note activity that reinforces the central ideas of the lesson.

Included in the Resource

• Student worksheet covering Earth materials and evidence of Earth's interior.
• Student Notes lines at the bottom of the worksheet for recording key ideas.
• Separate Answer Key PDF for checking student responses.
• Teacher Guide included in the Answer Key PDF, with Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes.

Practical Uses in the Science Classroom

Use this Grade 7 Earth science worksheet during a unit on Planet Earth, as guided practice after introducing rocks and minerals, or as independent review of evidence about Earth's structure. The questions give students opportunities to apply vocabulary, explain scientific reasoning, and distinguish what scientists observe directly from what they infer from measurements.

The answer key supports efficient response checking, while the accompanying teacher guide provides discussion prompts and teaching considerations for addressing misconceptions. Student Notes lines also offer space to record important ideas for later revision.

For Alberta science teaching, this resource provides focused practice connected to the stated Science 7: Planet Earth topic. It emphasizes the evidence and reasoning behind scientific explanations rather than asking students to treat a model of Earth's interior as a direct view of underground conditions.
