Earth's Changing Surface | 8 Lessons, Case Cards & a Project | Grade 4

Earth's Changing Surface is an earth science unit for Grade 4 with 32 pages of classroom material and a separate 13-page teacher guide. Students read rock layers as evidence, study weathering, erosion and deposition, use maps to find patterns, and compare design solutions for natural hazards. It is written for fourth grade teachers who want a self-contained NGSS-style unit with explanations, supported practice and reasoning cases.

The unit has eight lessons with the same three pages each: an explanation page, a practice page with explanation, and a case card. The first four lessons cover rock layers as evidence, weathering, erosion and deposition, and fair surface models. Lessons 5 to 7 look at how maps reveal patterns, resources and human use, and natural hazards and exposure. The last lesson compares design solutions. Two vocabulary pages, a learning check and a short project with a reflection page complete the unit.

What's Included

• Classroom Material: 32 pages (PDF, print edition)
• Teacher Guide: 13 pages (PDF) with answers, case guidance and assessment feedback
• Editable DOCX text editions of the classroom material and the teacher guide
• Presentation with 17 slides (PPTX)
• Original illustrations; the PDF is the print reference and DOCX line breaks may differ
• Vocabulary pages, a learning check and a project with a record and reflection page

The 8 Lessons

• Lesson 1: Rock layers as evidence – Reading rock layers as evidence of change.
• Lesson 2: Weathering – Describing how weathering breaks down rock.
• Lesson 3: Erosion and deposition – Describing how material is moved and laid down.
• Lesson 4: Fair surface models – Setting up fair tests with models of Earth's surface.
• Lesson 5: Maps reveal patterns – Using maps to find patterns.
• Lesson 6: Resources and human use – Looking at resources and how people use them.
• Lesson 7: Natural hazards and exposure – Looking at natural hazards and who is exposed.
• Lesson 8: Compare design solutions – Comparing design solutions for a problem.

Students Will Learn To

• Read rock layers as evidence
• Describe weathering, erosion and deposition
• Plan a fair test with a model of Earth's surface
• Use maps to identify patterns
• Compare design solutions for a natural hazard

Perfect For

• Grade 4 science teachers who need a closed unit on Earth's surface
• Teachers who want students to argue from evidence rather than memorize terms
• Classes that need a clear sequence from rocks to erosion to hazards
• Homeschool families looking for printable lessons with a separate answer guide
• UK and Australia: roughly Year 5

Why Teachers Choose This Unit

• Each lesson follows the same explanation, practice and case card pattern, so students know what to expect
• A lesson on fair surface models gives students a structure for testing erosion ideas
• The final lesson on comparing design solutions links the earth science to a practical problem
• The teacher guide has a teaching concept, sequence and preparation notes, answers for all eight lessons, an assessment key with feedback, and a differentiation and observation chapter
• Editable DOCX text editions allow you to adapt wording for your class

Every resource is built around the curriculum you teach – and if something doesn't fit your standards, the TeachLessons Guarantee applies: we adapt it for you.

Created with AI assistance. Texts and illustrations were generated with AI support and edited for classroom use; sources and production notes are at the end of the teacher guide.

Frequently Asked Questions

Which standards does this fit?

The content is closest to NGSS 4-ESS1 (patterns of Earth's changes), 4-ESS2 (Earth's systems) and 4-ESS3 (Earth and human activity). No alignment or endorsement is claimed.

Are answers included?

Yes. The separate 13-page teacher guide has answers and teaching notes for all eight lessons and an assessment key with feedback.

How long does the unit take?

The material does not state a duration. Plan by lesson: each has three pages, and you can use the lessons in order or choose the ones you need.

Does the unit cover natural hazards?

Yes. Lesson 7 covers natural hazards and exposure, and Lesson 8 compares design solutions. Maps are used in Lesson 5 to find patterns.
