C977: Science Methods: Secondary Chemistry

A guide to WGU's C977, the methods course on teaching high school chemistry through three-dimensional lessons, with laboratory safety certification.

Updated October 2026 · 5 min read

C977 Science Methods: Secondary Chemistry is a Western Governors University course on planning and teaching high school chemistry.

WGU describes it as focusing on science teaching methods for graduate students seeking an endorsement in secondary chemistry. You design standards-based lessons with the three dimensions of science, integrate technology appropriately, and evaluate, enhance and plan instruction in your content area.

Laboratory safety training and certification is part of the course, and earlier coursework in curriculum, instruction and assessment is a prerequisite. Chemistry teaching is demanding because students must connect what they see, invisible particles and symbolic equations all at once, often while handling hazardous materials.

Teaching Across Three Levels of Representation

Chemistry educators often describe three levels: the macroscopic (what students observe), the particulate (atoms and molecules) and the symbolic (formulas and equations). This idea is often drawn as Johnstone's triangle. Students struggle when lessons jump straight to symbols.

Example lesson, grades 10 to 11: Based on NGSS HS-PS1-7 (using mathematical representations to support the claim that atoms, and therefore mass, are conserved in a chemical reaction).

Macroscopic: students react baking soda and vinegar in a sealed bag on a balance, then repeat in an open cup, and compare masses. Particulate: they draw particle diagrams showing atoms rearranging, with the gas escaping in the open cup. Symbolic: they balance the equation and calculate the expected mass of carbon dioxide from the mass of baking soda used, then compare it with the measured loss.

The sequence moves from observation to explanation to calculation, so the maths has meaning.

Chemical Safety in the Classroom

Safety certification in the course covers safe practices, classroom procedures and personal protective equipment. Chemistry needs the most rigorous planning of the sciences:

Assessing Chemistry Understanding

A student can balance an equation correctly without understanding what is happening to the particles. Strong assessment in a C977 lesson therefore asks for more than numbers.

These tasks show whether students can move between all three levels, which is the core of chemical understanding.

Technology in Chemistry Lessons

Molecular modeling software and simulations make the particulate level visible, while pH, temperature and pressure probes give precise data quickly. A simulation can also replace an experiment that is too hazardous for a school lab. As always, explain why the tool serves the objective.

Where Students Get Stuck

Tips for C977

How We Help with C977

Send the task instructions, rubric, standard and evaluator comments. A science education writer with a chemistry background reviews your lesson, explains three-dimensional design, or prepares a model lesson and risk assessment to study. Our education assignment help guide covers other teaching coursework.

GradeEssays is independent of Western Governors University. Our help is for study and reference: plan and submit your own lessons under WGU's academic integrity policy. We never complete safety certifications or log in to student accounts.

Frequently Asked Questions

What does C977 cover?

Methods for teaching secondary chemistry: three-dimensional, standards-based lessons, appropriate technology and laboratory safety training and certification.

What are the three levels of representation in chemistry?

Macroscopic (observations), particulate (atoms and molecules) and symbolic (formulas and equations).

Why store chemicals by compatibility?

Alphabetical storage can place reactive chemicals side by side; compatibility groups reduce the risk of dangerous reactions.

What is an SDS?

A safety data sheet: the supplier's document listing a chemical's hazards, handling, first aid and disposal.

What is the prerequisite for C977?

WGU lists previous coursework in curriculum, instruction and assessment.

Can you write a model chemistry lesson?

Yes, as a reference to adapt. You plan, teach and submit your own lesson.
