  1. Cycles of Matter and Energy Unit 9, Lesson 2

  2. Laws of Conservation • Energy can neither be created nor destroyed, only changed or transferred • Same goes for matter (all the “stuff” we’re made of) • Key Question: If we can’t just make matter and energy, where does it come from when we need it?

  3. Water Cycle • Accumulation • Evaporation • Transpiration • Condensation • Precipitation • Start again!

  4. Carbon Cycle: Photosynthesis

  5. Carbon Cycle: Cellular Respiration

  6. What’s the Key? Opposite Equations!!

  7. Carbon Cycle: Overview

  8. Nitrogen Cycle

  9. Story Time! • http://blogs.agu.org/georneys/2011/05/28/blast-from-the-past-carbon-cycle-story/ • You will be writing and illustrating your own story as if you were a water molecule moving through the water cycle, a carbon atom moving through the carbon cycle, or a nitrogen atom moving through the nitrogen cycle. • Your story needs a beginning, middle, and end (at least 3 paragraphs) and must be written in 1st person (as if the carbon or water is telling the story) • You need 3 neat, colorful illustrations to go with your story. • Friday: Brainstorm • Monday & Tuesday: Write, draw, and practice • Wednesday: Present your story to the class
