We are learning about systems What is a system? A system has two or more parts that work together to make a new and different unit. This week we are focusing on the Vine Crop System. Can you put it together like a puzzle?!

We don't plant in soil, but we would like to study it. Please write to a friend or family member to ask for a small sample of soil for us to observe. Here is a sample letter:


 * November 17, 2014**
 * Dear Uncle Joe and Aunt Emma,**
 * Hello to my favorite aunt and uncle! I hope you are doing well. I really miss you and I hope I get to see you soon.**
 * School is going well, and I am studying plants and what they need in science in the greenhouse. Did you know we don't plant in soil?**
 * I am writing for kind of a funny reason: I need you to send me a small sample of soil from your backyard. We want to observe soil from all over the country (and maybe all around the world). Please put it in a small plastic bag or container and put a label to show where it is from.**


 * Thanks for helping me with science,**
 * Love your niece,**
 * Shakira**
