Original Prompt

i need a worksheet to teach this MS–PS1–6: Students who demonstrate understanding can undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes.

This learning resource focuses on understanding chemical reactions in relation to temperature control, specifically through the design and testing of devices that either absorb or release thermal energy. It highlights everyday applications, such as hand warmers and cold packs, and distinguishes between endothermic and exothermic reactions. The document guides students through the engineering design process, including planning, building, testing, and improving their devices. It provides materials and safety guidelines for conducting experiments, as well as prompts for reflection and redesign based on experimental results. Students are encouraged to apply scientific principles to evaluate their devices' effectiveness and consider real-world applications of their learning.
