Earth materials and interior evidence come together in this Grade 7 Science learning stations activity for Alberta's Planet Earth topic. Students examine how scientists use observable properties of rocks and minerals, direct evidence, and indirect evidence to build explanations about parts of Earth that cannot be reached directly.

Move from observations to scientific evidence

The station format gives students a structured way to compare different sources of information about Earth. As they work through the station cards, students record evidence on their station recording sheet and then complete a station wrap-up that brings the ideas together.

Students focus on scientifically useful distinctions and comparisons, including:

• Describing and comparing Earth materials using observable rock and mineral properties
• Separating direct observations from scientific inferences
• Considering what surface materials and exposed rocks can reveal about Earth
• Comparing drilling evidence with evidence from seismic waves
• Using multiple evidence sources to build and communicate models of Earth's interior

What you receive

• Station cards for the classroom rotation activity
• Station recording sheet for students to organize information from each station
• Station wrap-up for connecting evidence and ideas after the rotation
• Teacher Guide included in the Answer Key PDF, with learning objectives, teaching tips, discussion questions, and common mistakes

Built for evidence-based Earth science

This activity goes beyond simply naming rocks or recalling layers of Earth. Students work with the reasoning scientists use when direct access is limited: observe what can be examined, compare different kinds of evidence, and make supported inferences about inaccessible regions.

The combination of rock and mineral properties, seismic evidence, drilling evidence, and Earth interior models makes the resource useful when teaching how scientific knowledge about the planet is constructed from multiple sources. It also supports communication of evidence rather than isolated vocabulary recall.

Classroom use

Place the station cards around the room and have small groups rotate between them while completing their own recording sheets. After the rotation, use the station wrap-up to consolidate the lesson and the Teacher Guide discussion questions to support whole-class conversation. The activity can fit within an Alberta Grade 7 Planet Earth lesson sequence, a review of Earth materials and evidence, or practice distinguishing observations from inferences.
