Exploring Energy

Driving or Multi-dimensional Question:

How can we use thermochemistry principles to create emergency meals for refugees, soldiers and/or those displaced by natural disasters? Students will conduct investigations and analyze data to discover how energy transfer occurs within closed systems in order to better understand that energy cannot be created or destroyed, it only moves between objects, fields and/or systems.

Unit Summary:

In this PBL, students will explore the science behind thermochemistry and how energy can be harnessed to create emergency meals for refugees, soldiers and/or those displaced by natural disasters (emergency preparedness). Students will discover how “meals ready to eat” (MREs) work, then brainstorm and construct their own MREs using specific chemicals. Students will also explore how ratios can be used to generate specific amounts of heat. Students will share their findings and the importance of using thermochemistry to solve problems with their peers.

Standards

Science Standards:

PSCI.PS3 ENERGY
1. Identify and give examples of the various forms of energy (kinetic, gravitational potential, elastic potential) and solve mathematical problems regarding the work-energy theorem and power.
2. Plan and conduct an investigation to provide evidence that thermal energy will move as heat between objects of two different temperatures, resulting in a more uniform energy distribution (temperature) among the objects.
5. Investigate the relationships among kinetic, potential and total energy within a closed system (the law of conservation of energy).
7. Demonstrate Ohm’s Law through the design and construction of simple series and parallel circuits.
9. Demonstrate the impact of the starting amounts of radioactive substances upon the energy released.

PCSI.PS2 Motion and Stability Forces and Interactions.
7. Plan and conduct an investigation to provide evidence that an electric current can produce a magnetic field.

Disciplinary Core Idea: At the Macroscopic Scale, Energy Manifests Itself in Multiple Ways, Such as in Motion, Sound, Light and Thermal Energy. Energy is a Quantitative Property of a System that Depends on the Motion and Interactions of Matter and Radiation Within that System.
Science and Engineering Practices: Communicate Technical Information or Ideas About Phenomena and/or the Process of Development, Design and Performance of a Proposed Process or System in Multiple Formats.
Cross Cutting Concepts: Energy Cannot be Created or Destroyed—It only Moves Between Between Objects and/or Fields, or Between Systems.

Capstone Presentation:

Students will share their investigation findings and the importance of using thermochemistry principles to solve problems. Student teams will develop a mixed-media presentation explaining how they worked to develop a unique MRE using thermochemistry principles.

If there is an ROTC course provided at your school, students could tailor their presentations specifically to those students and instructors representing branches of the armed forces.
