In this project, you will design, build, and test a device that uses chemical reactions to manage thermal energy, such as a hand warmer or a cold pack. Through hands-on experimentation, you'll gather evidence to understand how these reactions work and how they can be harnessed in practical applications. This project will enhance your skills in planning and conducting scientific investigations, allowing you to explore the relationship between chemical processes and thermal energy management in real-world contexts.

By the end of this project, you will be able to design and test a device that uses chemical reactions to control thermal energy. You will gain skills in planning and conducting investigations, collecting evidence to support your design choices, and making modifications based on test results. You will understand how chemical processes can be applied to real-world situations, such as heating or cooling objects. You will also develop collaboration and communication skills by sharing your findings and receiving feedback from peers.

Design and construct a small device that either releases or absorbs thermal energy using a chemical reaction, such as a homemade hand warmer or cooler. Document your design process, including sketches, materials used, and modifications made after testing. Create a presentation or poster that explains how your device works, the science behind the chemical reactions involved, and how it can be applied to real-world situations.

Begin by exploring common devices that manage thermal energy, such as hand warmers or ice packs, and discuss their real-world applications. Conduct a simple demonstration using one of these devices to illustrate how chemical reactions can release or absorb thermal energy. Engage in a brainstorming session to identify everyday problems that could be solved by designing a new thermal energy device. Use this discussion to inspire your own project ideas and set the stage for your investigation.

Organize a science fair-style exhibition where you showcase your thermal energy devices to classmates, teachers, and family members. Prepare a presentation that explains your design process, the chemical reactions involved, and how your device manages thermal energy. Include a demonstration of your device in action, highlighting any modifications you made during testing. Facilitate a gallery walk where you can view and provide feedback on each other's projects, fostering a collaborative learning environment. Conclude with a reflection on what you learned and how you might apply these concepts in real-world situations.
