# Energy’s Transforming Power

Driving or Multi-dimensional Question:

How can stored energy be converted into another form for practical use? What energy is undergoing transformations? What energy is being transferred/conserved? What evidence is there that the energy is being conserved in this system?

Unit Summary:

According to the Cross Cutting Concept for Energy and Matter, students will begin to recognize types of energy present in a system and understand how this energy can transfer between objects. Based on several days of lessons and the Science and Engineering Practices, the students will create an evidence-based explanation for the relationships seen in the natural world and be able to identify evidence that supports other explanations. Explanations will be derived from the activities practiced in the course of the lessons as well as the culminating event regarding the student projects and presentations.

Assessment

Comic Strip:
Students will create a comic strip to show their knowledge of how stored energy can be converted into another form for more practical use.

Students should use their experiences learned through the activities to influence their comic strip.*

*See sample rubric.

Technology Integration:

Business Partner Contribution to Learning Experience Contact Information
Local Electrician Speak to students on how we use stored energy on a daily basis
Pizza Restaurant Donate cardboard boxes for the oven
Contractor Speak to students on how people are using different forms of energy to build their homes

Capstone Presentation:

Students will work towards a project that meets the disciplinary core idea for this PBL lesson. Students will work independently to formulate a comic strip with illustrations and words that show their understanding of how stored energy can be converted into another form for a more practical use. Students will be assessed using a rubric.
