Author(s): ​Ashley Colvin, Yunus Kinkhabwala​, ​Prof. Song Lin,​ ​Jonathan Neff, & Greg Sauer Date Created: ​October 2016 Subject:​ Chemistry Grade Level: ​Middle School Standards: Next Generation Science Standards (​www.nextgenscience.org​) MS-PS1-6​ Some chemical reactions release energy, others store energy. MS-PS1-6 ​Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes. MS-PS3-4 ​Plan an investigation to determine the relationships among the energy transferred, the type of matter, the mass, and the change in the average kinetic energy of the particles as measured by the temperature of the sample.
