Modeling Photosynthesis with Hopscotch in 5th grade

I have talked with some teachers recently about using programming to model systems.  This is great and super duper common core thinking as a way to demonstrate understanding. This is the text I am putting in front of my fifth graders today in STEM class.  I will update with pictures after class.

One of the ways we can demonstrate how well we understand a system is to create a simulation of that system.

Our Guiding Question
What are the significant parts of the system of photosynthesis?  How do they relate?

Getting Started
Begin by sketching the system you want to animate.  Think about which pieces need to move and change and which will stay motionless?

Take it to the Tablet
You will be using Hopscotch to animate a model of photosynthesis.  I suggest you investigate the emoji keyboard for the sun, rain, plants, flowers and arrows.

Your model needs to clearly show how photosynthesis works.  Be sure to get your basic functionality down first, and then make it more complex.

Let's see what they came up with:
