This learning resource, titled 'Is It Alive? Warm-Up Investigation,' aims to help students distinguish between living and nonliving things by identifying observable characteristics. Through a structured observation routine called See-Think-Wonder, students will examine four examples including a butterfly, a leaf, a growing crystal, a moving car, and a sleeping dog. They are encouraged to make detailed observations about what they see, think critically about whether each example is alive and the reasoning behind it, and pose questions related to their observations. Additionally, students will work collaboratively to define criteria that differentiate living from nonliving entities, fostering discussion and critical thinking.
