In this STEM and STEAM lesson plan, students explore how matter cycles through their ecosystem and how organisms get what they need to live. They follow the never-ending life of Spark, one tiny bit of matter, who leaves their own lungs and enters other life as close as a tree overhead to as far as a shark in the deep sea or the atmosphere of another planet!   With each reading, your students make new choices and have new adventures that inspire kindness for all forms of life.   Best of all, your kids use our imagination-kindling Student Sheets to design their own new adventures for Spark!
