We know about the light spectrum, the age spectrum, and sound spectrum, but do chemical reactions also occur on a spectrum? Young scientists experiment with partial reactions on a spectrum and observe the color changes. Then, they observe the impact of temperature changes to chemical reactions.

Instructional Ideas

• Provide the introduction and theory portions of the teacher resource to scholars before they begin the experiment

Classroom Considerations

• Relies on prior knowledge of chemical formulas, temperature, and chemical reactions
• Pair pupils with color blindness or visual impairments with others to help them distinguish color changes

Pros

• Provides tables for data collection
• Includes easy-to-follow instructions for each part of the experiment

Cons

• None
