Description
Life has existed on Earth for a very, very long tome, more than 3.5 billion years, in fact. Over the millenia, an amazing variety of life has evolved. From humble single-celled beginnings in water to incredibly complex and large multicellular organisms that exist in the widest range of habitats imaginable, the diversity of life that currently exists boggles the mind. 
 
Our unit, Diversity of Life, is broken up into 8 investigations with multiple parts and focus questions. 
 
This course supports the following principles set forth in A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas.

Diversity of Life 
 
Focus Question: How do you know if something is living? 
 
We are beginning the school year with a refresher on the growth mindset, so we can approach challenges with the right attitude and actions. Our first official unit is entitled, Diversity of Life, and in our first investigation of this unit, we will explore living and nonliving things. This week, students will observe the antics of a mysterious material when it is placed in water and record their observations. They will work in groups to sort pictures of objects into living and nonliving categories, defining the characteristics that qualify objects as living. Students will also set up mini-habitats for future study, using organic materials collected locally.
