This powerpoint is a unit guide that can be used over multiple days to guide students to think about the NGSS 4th grade standard 4. It helps students go through a series of open ended questions about the phenomenon Energy. There are slides that guide the teacher and students through the design process. There are extra slides that show the reading, writing, and math connections that can be used to plan for a Project Based Learning unit or to incorporate in a thematic unit about energy. I have other resources on this same standard to use with ELL's and vocabulary building.
