Description
What It Is:
A hands-on science design worksheet where students plan a device that uses an endothermic or exothermic reaction to absorb or release heat. Learners outline the device’s purpose, reaction type, materials, testing method, and improvement ideas, supporting NGSS-aligned engineering skills.
Why Use It:
This worksheet helps students apply chemistry and thermal energy concepts through creative problem-solving. It builds engineering design thinking, reinforces understanding of heat transfer and chemical reactions, and encourages analysis, testing, and iteration just like real scientists and engineers.
How to Use It:
• Identify the goal of the device (heating or cooling).
• Choose an endothermic or exothermic reaction and explain why.
• List the materials needed for the design.
• Describe how the reaction will cause a temperature change.
• Explain how the device will be tested for effectiveness.
• Suggest improvements based on possible outcomes.
Grade Suitability:
Best suited for:
• Grades 7-9: Guided instruction and structured design thinking
• Grades 10-12: Independent NGSS engineering design projects
Target Users:
Science teachers, students, STEM classrooms, engineering design units, homeschool families, and tutors teaching chemical reactions and thermal energy concepts.
