D857: Secondary Earth Science Curriculum

A study guide to WGU's D857, where undergraduate Earth science teacher candidates turn content knowledge into a teachable curriculum.

Updated October 2026 · 5 min read

D857 is the curriculum course in the undergraduate Earth science route at Western Governors University.

WGU describes it as preparing students to develop and evaluate Earth science curricula for secondary education, drawing on Earth's processes and materials, the hydrosphere, the atmosphere, and the universe.

It sits after the content courses such as astronomy, meteorology and geology, so the task changes from learning the science to organizing it for teaching. The difficulty is integration: connecting Earth-Sun-Moon relationships, internal and external Earth systems and the life cycles of stars and planets into one teachable sequence.

Curriculum designSequencing, activities and engagement for secondary students

WGU's description mentions practical examples and interactive activities as part of building engaging curricula.

Key Concepts Explained

Backward Design

Begin with what students should understand at the end, then decide how you will check it, and only then plan the activities. A unit that starts with a favorite activity often drifts away from its goal.

Example: Goal: students explain why seasons occur. Evidence: a labeled diagram plus a two-sentence explanation. Activities: a lamp-and-globe demonstration, a data task using day length at two latitudes, and a discussion that tackles the "closer to the Sun" misconception.

Integrating Sub-Disciplines

Earth science units are stronger when astronomy, geology and atmospheric science inform one another. Plate motion links to the rock cycle, the rock cycle to climate through volcanic gases, and climate to the hydrosphere.

Example: A unit on volcanoes can connect tectonics (where), rock types (what is produced), atmosphere (ash and gases affecting climate) and hazards (human response) in four linked lessons rather than four separate topics.

Matching Level to Grade

The same topic reads differently for grade 6 and grade 11. State the grade level, the prior knowledge you assume and the vocabulary you will introduce.

Typical Assignments and How to Approach Them

WGU's guidebook does not list task prompts. The table describes kinds of work curriculum courses typically use. Follow your own instructions and rubric.

Work typeWhat it testsHow to approach it
Unit outlineSequencing and coherenceShow goals, evidence and activities in order
Lesson planPractical designInclude timing, materials, checks for understanding
Content rationaleAccuracy and depthExplain why each topic belongs and how it connects
Assessment designMeasuring learningAlign each question to a goal

A Study Approach That Works

  1. Review content gaps first. Teach yourself the weakest sub-discipline before designing around it.
  2. Pick a unifying idea. Energy flow or systems interaction are common threads.
  3. Draft goals, then evidence, then activities.
  4. Check integration. Mark where each lesson touches another part of Earth science.

Study Tips for D857

How We Help with D857

Send the task instructions, your standards, the rubric and any feedback. A tutor can explain backward design with fresh examples, review your unit for integration, edit your plan for clarity, or prepare a model unit on a different theme for you to study. See our education assignment help guide for wider support.

GradeEssays is independent of Western Governors University. Our work is a study and reference aid: use it to understand the method, then complete and submit your own work under WGU's academic integrity policy.

Orders are written from scratch, include free revisions within the scope of your original request, and are refunded in full if late. We cannot promise that any assessment will be passed.

Frequently Asked Questions

What is the difference between D857 and D858?

Both share a WGU description of developing and evaluating Earth science curricula. D857 is in the undergraduate route; D858 is in the Master of Arts route for licensed teachers.

Do I need to design a full year of curriculum?

Not necessarily. Follow your task instructions, which set the scope.

Which grade level should I choose?

Follow your task. If it is open, choose one and apply it consistently.

How do I show integration across Earth science?

Link lessons explicitly, for example tectonics to rock cycle to hazards, and say so in the rationale.

Can GradeEssays write my D857 unit?

No. We provide tutoring, model examples and editing. You complete and submit your own work.

Where do I find assessment details?

On your D857 course page and with your instructor. WGU sets the assessment.
