Sustaining Rigorous and Responsive Teaching Based on Carbon: Transformations in Matter and Energy (Carbon TIME)

Carbon TIME was an NSF-funded STEM+C project that included publicly available teaching units, assessments, teacher professional development, and teacher networks based in local education agencies. Still available NGSS-aligned resources focus on processes (e.g., photosynthesis, cellular respiration, combustion) that transform matter and energy at multiple scales.
